The main stages of designing machines.The state standard specifies 5 stages of development of construction documents for products of all branches of industry: technical assignment, technical proposal, sketch project, technical project and development of working documents.
In the process of preparation of construction documents, the project is gradually defined and closer to the development of working documents. According to these working documents, the product is produced.
The multi-stage design process shows the complexity of the task and the high demand for the quality of the received solutions. Because errors have to be corrected during the production process. This leads to unnecessary additional spending of time and resources. The technical assignment includes the technical characteristics of what the machine is intended to do, quality indicators, as well as the technical and economic requirements for the machine being developed, the number of stages of work on the construction documents, and special requirements. It is better to specify the development base, the amount of the consumed and planned product, the duration of its preparation, and the possible ways of modernization in the technical assignment as much as possible.
The technical proposal has a technical and economic basis for creating a machine according to the technical assignment. The technical proposal includes possible options for the implementation of technical tasks, comparing the construction being developed with similar constructions, patentability of the machine, and so on. After the technical proposal has passed agreement and approval, it can be the basis for carrying out the next stages of the work.
The sketch project includes the principle solutions of the structure and principle of operation of the machine, as well as information defining its service function, main parameters and general appearance. After agreement and approval, the sketch project can be the basis for moving to the next stages of the project.
The technical project determines the complete technical solution, which provides a complete idea of ​​the machine structure, as well as initial data necessary for the preparation of the working document. After the approval of the technical project, it can become the basis for the development of working documents.

Working papers are used for batching, serialization and mass machine development. In the process of working on working documents, technological and organizational factors of production are fully taken into account.This stage is quite continue is enough and the most a lot time and tools at the expense of have.
