CNC Machining Parts Features And Features
CNC machining process analysis of parts is the preparation of numerical control program in the most important and extremely complex links, but also CNC machining process design core work, CNC Machining Parts must be completed before the NC processing program. A qualified programmer has a clear and comprehensive understanding of the functions and characteristics of CNC machine tools and their control systems, CNC Machining Parts as well as every aspect that affects CNC machining, so as to avoid product quality that may occur due to ill-treatment of process options Problems, resulting in unnecessary human, material and other resources of the waste. The views of the parts should conform to the requirements of the national standard, the location is accurate and the expression is clear; the relationship between the geometric elements (points, lines, faces) (such as tangency, CNC Machining Parts intersecting, parallel) should be accurate; dimension should be complete and clear.
Comprehensive and reasonable numerical control processing technology analysis is to improve the quality of NC programming an important guarantee.
In the numerical control processing, from the parts design drawings to the finished product qualified delivery, not only to take into account the NC program preparation, CNC Machining Parts but also taking into account such as parts processing route arrangement, the choice of processing machine tools, cutting tool selection, parts processing The positioning of the fixture and a series of factors, before the start of programming, CNC Machining Parts must be part of the design drawings and technical requirements for detailed CNC machining process analysis to determine which parts are the key technology, which is the difficulty of CNC machining, As well as the difficulty of NC programming.
Part of the process analysis is also the first step in numerical control planning, on this basis, to determine the parts needed for CNC machining CNC machine tools, CNC Machining Parts processing tools, process equipment, cutting the amount of CNC machining process line, in order to obtain the best processing technology Program, and ultimately meet the parts engineering drawings and related technical documents.
Most parts design drawings define only the shape and size of the parts, and do not specify the raw blank material, including the type of wool, specifications, shape, heat treatment status and hardness. Programming, the in-depth understanding of wool is an important start, the use of these original information, is conducive to numerical control program planning.
For the assembly diagram of the analysis and research, CNC Machining Parts is mainly familiar with the product performance, use and working conditions, a clear parts in the product of the assembly position and role, understand the parts on the basis of the technical conditions to find out the main technical key Problem, lay the foundation for the development of the correct processing plan. Of course, CNC Machining Parts ordinary parts for process analysis, you can not carry out the analysis of assembly drawings.
The analysis and research of the parts is mainly about the parts of the process review, such as checking the design drawings of the view, size, CNC Machining Parts technical requirements are wrong, missing, especially for the poor structure of the parts, if possible and design Personnel to communicate or make changes, by the designer to decide whether to make the necessary changes and improvements.
