What is a technological project? Development of a technological project. Example of a technological project

What is called a technological project (TP)? How is it developed? What structure does it have? Within the framework of the article, not only general information will be given, but together we will consider the compilation of technological projects by example. Each step will be described in detail.

What is a technological project?

The term is understood to mean one consolidated or a whole set of documents. Similarly, the result of the design process is usually called. The latter is in one way or another present in all serious strategies.

The design process is a reflection of the worldly principle: before you do something, you need to think it over. A technological project is necessary in order to fix the results of consideration.

Why is TP necessary?

TP is necessary for executors to create a product that has been ordered. Thus, it is difficult to overestimate the importance of the technological design of production during the negotiation and discussion of key design decisions. After all, in order to ultimately realize its products, it is necessary that it meets certain parameters and requirements.

And why would you need another technology project? A sample of this document can provide invaluable assistance to other specialists in the solution of various tasks.

Building

The development of a technological project is a time-consuming task. The main requirement for the result is to clearly and clearly reflect how it is necessary to realize what was conceived. And the understanding of this, in the end, should be for all:

• From the manager;
• analytics;
• Development;
• Engineer;
• Handyman;
• Customer.

Based on this aspect, the structure of the technological project is described from the top down. Initially, it is necessary to focus on the highest level of abstraction and finish on the details of the implementation of individual elements.

In the work on different parts, specialists of various orientations can take part: a leading developer, an analyst, an architect, an administrator and any other personnel whose knowledge may be important.

And now let's look at an example of a technology project. We will develop the process of manufacturing parts for the machine.

Technological analysis

First, you need to conduct a technology analysis. By this we mean the establishment of a set of indicators and properties that will make it possible to manufacture a part with minimal costs. At the same time, the required accuracy will be maintained as shown in the drawing.

Technologicality is preliminary estimated when compared with available analogs. The estimation is exposed depending on qualitative and quantitative indices. The latter include:

• Material consumption;
• Labor intensity;
• Unification of elements;
• Requirements for the quality and accuracy of surfaces.

Quality indicators are not so universal and vary depending on the details of the part.

Workpiece selection

The next stage has a significant impact on the technology project. After all, from the correctly selected workpiece can change the process, economy and laboriousness of processing to obtain the desired detail.

It is necessary to take into account a number of factors: production volumes, possible materials, designs, dimensions and accuracy of work performance. Depending on the required, in our case, they will do:

• Investment casting;
• stamping;
• injection molding;
• Profile rolling;
• Casting into shell molds;
• Periodic rental.

When the method by which the workpiece is obtained is selected, its contour must be filled with thin thin lines into the drawing of the part.

Choice of technological base

The next question is solved simultaneously with the previous one. To choose the scheme of basing it is necessary being guided by the design and technological requirements. It largely determines the sequence in which the processing will take place, the design of the devices, the productivity and the achievement of the specified accuracy.

When a technological project is being developed, then each operation must have its original bases and dimensions. It is necessary to adhere to the principle of unity in the work. In other words, the technological and design bases should be combined. If a decision is made to depart from this, then be prepared for such consequences:

1. It will be necessary to toughen the tolerances to the original dimensions;
2. The position of the workpiece during the processing must be constant and not change.

We are developing a routing technological process

This stage depends on the design features of the part and the required accuracy. The sequence of processing actions should be as follows:

1. Base surfaces change.
2. A roughing is performed, during which the most allowance is removed.
3. We are working with surfaces that will not affect the rigidity of the workpiece.
4. Processing of parts where high accuracy is not necessary is carried out.
5. Closer to the end of the technological process, finishing operations are carried out.
6. Bringing the details to the necessary parameters so that it can be used in the future.

Developing operating technology

The development of opractive technology consists of several processes. It is desirable to coordinate them already with those who will work with the details in practice. The design of this stage depends on the structure of the operation, the equipment chosen, various devices, certain time norms and processing modes.

The content must necessarily indicate the transitions, in the sequence of their execution. They should be aligned in such a way as to provide the highest rates of economy and productivity in performing the operation.

Also, within the limits of the technological project it is necessary to define admissible allowances. They can be assigned as general or intermediate.

Then it is necessary to devote time to equipment and technological equipment. So, for small-scale or single production it is necessary to use universal devices. And in order to avoid wasting time, roughing and finishing is done in a single operation. True, this is only suitable in cases where there is no need to achieve significant accuracy.

Calculation of modes

At the stage of calculating modes, in our situation we pay attention to the one that is responsible for the processing and the time norm. The sequence of mechanical actions for the machine in this mode is determined in the following sequence:

1. The cutting depth is set.
2. The tool feed is selected.
3. The cutting speed is calculated.
4. Check the operating mode and power of the machine (is it possible to do so)?
5. The main time required for the technological transition is also determined.

Now you need to calculate the machine (or the main) time. For example, for turning or drilling operations, the following formula is used: RDOP / (PW · POOSH) · PE, where:

• RDPO is the estimated length of the surface that is being processed;
• CHO - the number of revolutions that the spindle makes per minute;
• POsH - feed per revolution;
• PE - the number of passes.

Although, it is worth noting that the author slightly skidded. In general, you have an idea about the technical side of the case - everything that relates to the object for which the technical design is drawn up should be indicated here . For completeness of understanding, it remains only to consider what needs to be added to the graphical part.

We design the graphic part

It should be possible to make a copy of any document. It is also desirable to automate the accounting of all information that is recorded to them.

Within the framework of many professions, various forms were provided, with the help of which it is possible to provide necessary information quickly and without loss of detail.

Conclusion

When drafting a technological project, consider that the information provided in the article is just a certain compilation of what should be. And so that you can understand how difficult everything is, let's take a quick example of the site on which the text is located.

To describe all of its possible functions and interaction features, you will need documents that will take from a hundred pages (and not the fact that there is not more). It would seem that there is something complicated here? But in fact, it is necessary to provide a number of details, which account for the bulk of all the aspects of performance introduced.
