CNC machining program customization steps are:
1, analyze the parts of the working drawing and product assembly diagram
Understanding the use of the product, performance and working conditions, for the position of the parts in the product, the function and technical requirements for clarity, which is the basis of CNC machining.
2, process review
The process review is related to the accuracy and quality of the product after processing, you need to review the size of the drawings, views and technical integrity, analyze whether the technical requirements of scientific, reasonable and appropriate.
3, to determine the types of blanks and manufacturing methods
To determine the basis of blanks is mainly the role of parts in the product, the structural characteristics and dimensions of the parts themselves, the parts of the material and process characteristics, as well as the parts of the production batch and so on. Often used types of blanks are castings, forgings, weldments, stampings and profiles and so on.
4, the development of CNC machining process route
Mainly contains: selecting the positioning reference, determine the processing method, arrange the machining sequence and arrangement of heat treatment, inspection, and other processes and so on.
5, to determine the process required for the machine tool and process equipment
Process equipment includes fixtures, tools, gauges, auxiliary tools. Under the premise of ensuring the quality of parts processing, and production batch and production beat to adapt to each other. It is recommended that priority be given to the use of standardized process equipment and make full use of existing conditions, in order to reduce production costs. For the special machine tools or groups of equipment must be modified or redesigned, should be based on the economic analysis of the design task proposal.
6, to determine the machining allowance for each process, calculate the process dimensions and tolerances
7, to determine the amount of cutting
Principle: to ensure that the parts machining accuracy and surface roughness, to give full play to the cutting performance of the tool to ensure that a reasonable degree of durability of the tool; and to give full play to the performance of the machine tool to maximize productivity and reduce costs.
8, to determine the working hours of each process quota
According to the production conditions of the enterprise, the development of the majority of workers can achieve and approach a reasonable level of effort.
