CNC machining is a programmable flexible processing methods, its popularity greatly improve the processing efficiency. But in the processing technology, in addition to requirements of CNC machine tools has a strong ability to control movement and, more importantly, how to efficiently obtain high-quality CNC machining process, and from the process as a whole to improve production efficiency. As part of the increased complexity and limited skills of workers, manual programming more difficult.
CNC machining applications can greatly improve productivity, stability, processing quality, shorten the processing cycle, increasing the production of flexible, to achieve a variety of complex precision components for the automation of processing, and improving the ability of the market to adapt and improve their overall economic efficiency.
In this paper, CATIAV5R20 as a tool,complete the adjust frame three-dimensional modeling and simulation process. Include: First, based on the adjusted frame structural features and technical requirements, in its process analysis, to determine the part of the processing methods. By checking in a timely manner toolpath tool found between the parts with undercuts and under cut. And through the virtual machining process simulation tools found in advance of the moving parts, jig and tool interference and collision between the determined interference collision occurred and the corresponding position of the NC block, and previous design and NC program to be modified.
