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, easy to implement in a factory or workshop computer management, reducing the total number of workshop equipment, saving manpower, improve labor conditions, help speed up product development and upgrading, and improving the ability of the market to adapt and improve their overall economic efficiency.
In this paper, UG NX 5 as a tool,complete the punch three-dimensional modeling and simulation process. Include: First, based on the punch structural features and technical requirements, in its process analysis, to determine the part of the processing methods. Then, using UG / CAD module to complete the part geometry parametric modeling. On this basis, the use of UG / CAM module for NC programming, design the machining line, the tool path, cutting mode and other parameters, to generate a part of the NC program.
