Organization and planning of production at JSC "Baranovichi Plant of Machine Tool Accessories". Production process Procurement area in production

Purpose of the lesson: to study the basic operations and equipment of forging production when obtaining packages, disks, shafts, compressors.

Marking of steel blanks

Metal coming from metallurgical plants has its own factory marking. Each rental, bloom, and square has a release on the end side. This stamp indicates the steel grade and heat number. There is also an accompanying document - a certificate.

Marking steel blanks after cutting them

After the steel blanks are cut at the procurement area, all metal (rolled, blooms, square) is marked with paint according to the marking table:

6.5.1 Heating of workpieces before forging

Before forging, the workpieces are heated in a furnace to the following temperature:

Table 2.

6.5.2 Heating ovens, loading and unloading of heated workpieces

Heating gas furnaces are a metal frame lined with a fold of refractory brick that forms the working chamber of the furnace. Serves for supplying gas to smoke exhaust channels and working windows, for loading and unloading metal, covered by lifting doors. The fuel used is gas. An overhead crane and a forging shovel are used to load the workpieces into the furnace. Small workpieces are thrown by hand. The heated workpieces from the furnace are unloaded from the furnace using a forge poker. Temperature control is carried out using a pyrometer or visually - by color. (see table 1)

The production workshop of the Ufa Metal Structures Plant is a workshop with an area of ​​13,000 m2, which houses the equipment necessary for the manufacture of tanks, vessels, apparatus and building metal structures for various purposes. The production workshop's capacity allows us to produce up to 1,200 tons of metal structures monthly.

The beginning of the formation of the concept of a new organization. The merger of two interacting companies (one manufacturing, the other trading) will significantly reduce taxation and streamline the management system. Since the staff of company X will be largely staffed by former employees of company Z, the question arises of maximizing the formalization of relations at the very initial stage of work on creating a new organization. Using the concept of types of organizational paradigms (systems) by L. Konstantin, the desired system was defined by management as closed, based on strong leadership, with formal communications subject to general rules.

At the first stage of work on structuring the organization, a diagram of the technological process of jewelry production was drawn up, which made it possible to identify the main structural divisions with their specialization, a system of direct subordination, and communication links between divisions.

The next step is to develop an optimal management structure based on an analysis of the technological process diagram. The following structural divisions were identified: raw materials warehouse, finished product warehouse, chemical laboratory, procurement area, melting area, volumetric casting area, special casting area in graphite molds, jewelry assembly area, weighing, packaging, engraving areas, accounting, personnel department, secretariat .

Divisions related to the main production are directly subordinate to the production manager, and auxiliary production divisions are directly subordinate to the general director. The engraving department, which is both part of the main production and performs auxiliary functions, reports to the production manager and works at the direction of the marketing department of a related company.

It should be noted that the production structure described above, due to some objective reasons, cannot be completely created immediately. But this is exactly the model of organization that we want to achieve by performing a series of sequential steps.

As already noted, the desired system was defined by management as closed, based on strong leadership, with formal and rules-based communications. The principle underlying the division of labor is functional. Managers, specialists and performers were identified.

Supervisor organization - the general director who manages the organization's resources.

Specialists - chief accountant, production manager, warehouse manager, personnel manager - do not have administrative power, but are experts in a certain field and assist the manager in the decision-making process.

Traceability of material from part to finished product is a task that is especially relevant for mechanical engineering enterprises. It is obvious that without the use of information systems it will be extremely difficult to solve such a problem, therefore the corresponding requirement is one of the first in a series of those that machine builders impose on IT solution providers. Nevertheless, many expect from information systems, if not a miracle, then certainly a magical red button that will solve all problems.

In this article, we made an attempt to understand what an information system is really capable of solving, and what should remain in the sphere of human responsibility: what decisions should he make, what actions should he perform, and what data should he provide to the information system in order to achieve the desired result from it.

Without pretending to comprehensively cover the issue, we will dwell on its most important component - we will consider the first steps, on which, however, the fundamental possibility of solving the entire problem will depend. Moreover, let’s consider these steps using the example of a solution for an enterprise whose industry dictates the most stringent requirements for traceability: for each product, or more precisely, an instance (serial number) of a product, it is necessary to have information about the specific characteristics of the material from which all its components were made.

In such conditions, it is important to properly organize information support for processes at the initial stages of production, that is, at the materials warehouse and further at the procurement site.

This article will focus on the project being implemented at Energotex CJSC (Kurchatov). The TechnologiCS system (www.technologics.ru) is used as a tool for automating production accounting processes.

Note that traditionally such problems are solved by warehouse accounting methods, usually implemented within the functionality of accounting (accounting) systems. Traditionally, solving a problem using such systems looks like this:

  • accounting of primary documents (invoices and invoices) received from material suppliers;
  • distribution of material among receipt batches with individual (primarily price) characteristics;
  • release of material into production (write-off from the warehouse using an invoice);
  • arrival of workpieces from the production (procurement) site to the corresponding warehouse.

However, upon closer examination, it turns out that at each of these steps a much more complex problem must be solved, and the greatest difficulties arise already at the first stage of its solution.

Let's explain what was said:

  1. From the point of view of an accountant, material is what is recorded in the position of an accounting document, and this document was created by a third-party organization (supplier), which does not think too much about the rules for recording the name adopted at the consumer enterprise.
  2. From the designer's point of view, the material is what is written in the title block of the drawing (usually the grade of the material). Additional requirements for the material may be given in the technical specifications, but this is just text.
  3. From the point of view of a technologist, the material is already a workpiece. This means that the record about the brand of material should be supplemented with information about the product range, standard size and other similar data.

The manufacturer is even more demanding when it comes to recording material. In addition to all the information already mentioned, he needs data on the individual characteristics of a specific batch of material, down to the actual geometric dimensions, heat number, chemical composition and physical properties of the material within a given batch.

Then we will try to figure out where this information comes from. Obviously, there are two sources, and at a certain stage, information arising in each of them occurs and must be combined. An explanation is given in Fig. 1.

From the explanation it is clear that the main and inevitable conflict arises already at the first stage of production accounting - this is the problem of identifying the material received from the supplier and the workpiece material specified in the design and technological documentation of the manufacturer.

The solution to this problem is based on the use of special functionality of the TechnologiCS system - settlement and accounting documents, as well as on the mechanism of their interaction.

Unlike the classic warehouse system, which works only with accounting documents, on the basis of which accounting objects move through the warehouse and, as a result, their balances change, TechnologiCS also operates with so-called settlement documents.

A settlement document is a special system object that also has a specification, operates with quantities and other attributes characteristic of a warehouse document, but does not directly affect the movement of accounting objects. It can be, in particular, the basis for a number of accounting documents, and in this case the content of the accounting document (specification) will be generated automatically using the corresponding specification of the basis document.

Now it is time to specify the steps that must be performed in the production system to solve the problem of end-to-end material tracking within the procurement area. Let us recall that the solution to this problem will be the foundation for the implementation of tracking this chain right up to the finished product.

So, we need:

  1. Receive information about the receipt of material at the central warehouse.
  2. Identify the received material and the workpiece material specified in the documentation (contained in the TechnologiCS database).
  3. Clarify and record information on the geometric dimensions of the material, determine a list of additional tests.
  4. Issue the material to the cutting area (transferring the material to the “Blank” state).
  5. Carry out cutting of material in the cutting area.
  6. Form so-called s A dki (with A dka - a group of workpieces simultaneously subjected to heat treatment).
  7. Conduct hardness tests on samples after heat treatment.
  8. Record the test results.
  9. Move the workpieces to the storage area of ​​the procurement area.

Rice. 2 explains the first two steps of the above sequence. The features of the procedures that are performed at these stages imply the adoption of decisions that require appropriate qualifications from the specialists making them. Obviously, the storekeeper cannot be required to solve the problem of identifying material, and the functions performed by the storekeeper should be as mechanical in nature as possible - thereby eliminating inaccuracies and errors in subsequent steps.

RD - TechnologiCS settlement document
UD - TechnologiCS accounting document

It is important to pay attention to a key point here: the supplier’s invoice, before falling into the hands of a warehouse worker (storekeeper), undergoes preliminary processing in the logistics service (OMTS).

The OMTS employee, having information about the chain of documents that generated the invoice (his own application, the supplier’s invoice and the invoice itself), has the opportunity to make a decision on the compliance of the supplied material with the position of the TechnologiCS materials directory. In addition, the application specification, being formed on the basis of production needs calculated in the same system, increases the chances that the supplier’s invoice will contain the same items - this is a significant aid to the OMTS employee in making a decision.

The result of processing the supplier's invoice in OMTS is the settlement document “OMTS Receipt” (Fig. 3).

The positions of the specification of the settlement document are already links to the corresponding TechnologiCS reference book, and this gives the storekeeper the opportunity, when creating an accounting document - the invoice - not to think about the content of the specification, but simply create a document “based on”.

It should be noted that in the process of creating a settlement document, the OMTS employee uses specially designed macros and input forms that help him, already at the initial processing stage, provide specification items with the maximum possible set of information characterizing the incoming material, which significantly facilitates the work of services that use this information on subsequent stages of material movement (Fig. 4).

After the settlement document has been created and the OMTS employee has entered into it all the necessary information about the received material, you can post the material to the warehouse.

The action is carried out by the storekeeper, and he does not create a receipt manually, but uses a special macro function that generates an invoice based on a settlement document. Thus, the possibility of any errors occurring at this stage is practically reduced to zero.

The result of the storekeeper’s work is the completed accounting document (Fig. 5).

Carrying out an accounting document caused the movement of material in the warehouse and a change in its balances (Fig. 6).

Please note: the capitalized material is distributed among accounting cards in such a way that each card corresponds to material with the same properties, for example, certificate and heat number.

Each batch of material received its own serial number, which will subsequently be traced in blanks and further in parts and products.

The next stage is the so-called transition of the material into the workpiece. This action requires a special decision, and therefore has special significance. The representative of the technical control service, having complete information about the remaining material in the warehouse, as well as a comprehensive description of each batch of material, decides which specific blanks can be made from each batch.

Additional laboratory testing of material samples may be required during the decision-making process.

The decision on the need for such tests is recorded in the settlement document “Work Order” (Fig. 7).

Rice. 7. Creation of work orders for additional tests

For each settlement document “Work Order”, a special card is filled out, where specific types of tests that need to be carried out in the laboratory are noted (Fig. 8).

Please note: the full list of tests is predetermined. When making a decision, the employee only notes those that are necessary in this case.

Based on the created calculation document, a test task is automatically generated (Fig. 9).

When a decision is made to produce blanks from specific batches of material, it becomes possible to attach metal cutting cards to each batch, which, in turn, constitute the contents of the corresponding TechnologiCS directory (Fig. 10). Each card in TechnologiCS has a specification containing specific blanks that are obtained during the cutting procedure.

Rice. 10. Linking metal cutting cards to serial numbers of material batches

The result of this action is the automatic generation of a “Requirement” document, which is the official basis for receiving material from the warehouse (Fig. 11).

In order not to overload the article with technical details, we deliberately omitted a number of actions that precede and follow the formation of this document. Let us draw the readers' attention only to the fact that the actions that make up the procedure for transferring material to production are maximally automated and come down to the sequential launch of a number of macro-functions that form a chain of settlement and accounting documents, one based on the other.

In none of the cases does the employee need to manually fill out the content of the document (specification); he must only at certain moments add the necessary additional information to the relevant positions and carry out the accounting document, thereby confirming the fact of the movement of material.

Let us dwell in more detail on one more key point of the process. We already know which batches (serial numbers) of material are in the warehouse, a decision has been made to produce specific blanks from these batches, and cutting cards are attached to the batches. To transfer material to the material cutting section, the procurement section master runs the “Transfer of material to workpiece” macro, having previously selected the necessary lines in the specification of the accounting document “Reception by invoice” corresponding to the materials transferred for cutting (Fig. 12). In this case, an expense accounting document is created, as well as a settlement document “Requirement” (Fig. 13).

The algorithm for drawing up the specification of the settlement document “Requirement” is as follows:

  • the “Cutting map” parameter must be linked to each item in the specification of the accounting document “Reception by invoice”;
  • if this parameter exists, then the “Quantity” value for the same item from the specifications of all cutting cards will be added up and, together with the name of this item, will be recorded in the specification of the settlement document “Requirement”;
  • if the parameter for the specification item is not specified, the system will prompt you to enter the number of blanks for each such item of the accounting document “Reception by invoice”.

Upon delivery of the material to the cutting site, the warehouseman receives an accounting document, thereby removing the material from the remainder of the warehouse and moving it to the financially responsible person of the cutting site (Fig. 14).

We draw the attention of readers to the fact that the settlement document shown in Fig. 13, connects a batch of material with certain individual characteristics and a specific workpiece. This makes it possible to automate the further sequence of actions performed by the macro (Fig. 15):

  • for the cutting area, create an incoming accounting document “To work at the area”;
  • for each item item specified in the specification for the cutting card, create as many blank registration cards as were indicated in the “Quantity” column of the “Requirement” settlement document (see Fig. 13);
  • assign each workpiece a unique serial number corresponding to a specific heat and position from the cutting card specification;
  • capitalize the document.

Having illustrated in detail the main points that make it possible to organize end-to-end information tracking of the movement of material in the process of its transformation into a workpiece, we note that the functions of the procurement section include a number of actions that precede the transfer of workpieces for further processing:

  • heat treatment of workpieces with automated formation of cages;
  • sampling from each cage;
  • conducting hardness tests, entering the results of the tests;
  • moving workpieces to the storage area of ​​the procurement area.

These actions are performed according to algorithms that are fundamentally no different from those given above. They are based on the automated formation of chains of settlement and accounting documents based on each other. The result of these actions is the appearance of additional data that individually characterizes the workpieces from each batch (Fig. 16).

In conclusion, let us once again formulate the basic principles underlying the solution to the problem of tracking material from receipt at the warehouse to specific workpieces:

  • in the process of organizing information support for the movement of material, it is necessary to make a number of fundamental decisions;
  • such decisions can be made by an employee with the appropriate competence;
  • the process information support system must provide this employee with the necessary information to make a decision and record the result;
  • the system should automate routine functions related to warehouse accounting as much as possible, while eliminating manual input of the content of documents;
  • the system must also unambiguously predetermine the sequence of actions performed by employees.

Note that in our case, the information system correctly separates the processes: the decision on the initial identification of the material is made by the OMTS employee, the storekeeper only records this decision with a receipt document; the decision to conduct additional tests is made by the STC employee, the site foreman uses this decision when writing off specific batches of material for production, etc.

CJSC "Energotex"

CJSC Energotex (Kurchatov) is one of the leading CIS enterprises producing high-tech equipment for nuclear power plants. The list of its main products includes equipment for storing spent nuclear fuel, equipment for nuclear and thermal energy.

The production capacity of the enterprise and the qualifications of its engineering and technical personnel allow it to produce almost any mechanical engineering product.

The mechanical assembly production has a fleet of CNC machines that provide high-precision mechanical processing of parts weighing up to 30 tons. Modern equipment is used in the procurement, assembly and welding production.

Over 18 years of development, more than a hundred types of products have been mastered, and the structure of the enterprise is maximally adapted to the characteristics of production.

The system automates routine functions and unambiguously determines the sequence of their implementation: a warehouse employee (storekeeper) runs macros that carry out related chains of necessary actions and generate documents, and the storekeeper only records the fact of the movement of material by posting documents. This eliminates errors that inevitably arise during manual processing of documents.

As a result, each workpiece with a unique serial number that appears in the warehouse carries comprehensive information about the material from which it was made. The workpiece automatically inherits it along the chain of documents accompanying the processing processes.

It is not difficult to understand that, using similar algorithms, it is possible to trace the path of the workpiece to the finished product, and this task is of a purely technical nature. At the same time, the foundation, which is the basis for its solution, is laid precisely in the first steps of recording the material and processing it at the procurement site.
