Abstract
In this paper, rotating shaft parts for CNC machining technology of the bank analysis, it profound meaning, this article will be about it. Part of the process design the content of main machining process planning, machining process design, process design, and machine tools, tools, fixtures, etc. choices. Analyzed Machining of parts and used over and the program structure, such as the reasonable use of G71, G73, G70, G92 and other commonly used parts combined-cycle instructions roughing, finishing the program design. In addition, the design process has started processing the corresponding discussion, and come back transformation of such parts of the general processing steps.
Topics learned throughout the discussion of this professional knowledge and practical operating techniques, from analysis and design to the calculation, the operation that finished at the same time this provides a self-learning topics, self-selection, self-completion opportunities. Graduation design practical, comprehensive, exploration, and applicability, this topics purpose constitute the teaching system of numerical control CNC technical expertise and professional skills important part is to use the actual operation of a CNC machine tool Exercises.
Key words: dimensional accuracy of process design programming
