Numerical control technology is the base on machining automation technology. And it is the core technology of Numerical control machine, the level of its strategic position in relation to the level of the country's comprehensive national strength and reflect the housekeeper. Numerical control technology is the core technology of the advanced manufacturing technology and equipment, machinery manufacturing competition, and its essence is the competition of numerical control technology. Numerical control technique has already become the central technique of the manufacture. Meanwhile, it is faced with revolutionary changes while the computer technique is developing swiftly and violently. Computer emulation and simulation technique is now the pre-requisite for practical processing. It reduces much of the workload and improves the work efficiency as well. The most important thing is the technique has already cut down the waste of the raw materials in the production procedure and even saved a lot of costs.
Numerical control technology requirements programmers to master UG, Pro-E, Master CAM software for application, and this paper is the use of CATIA software for CNC machining, using VERICUT software for machine simulation.At present, CATIA is now in the CAD / CAE / CAM and PDM in the field of leadership has been recognized worldwide, are widely used in the aerospace, automobile manufacturing, shipbuilding, machinery manufacturing, electrical / electronic consumer goods industry, its integrated solution the programs cover all product design and manufacturing, its unique DMU electronic prototype module function and hybrid modeling technology is to promote the competitiveness of enterprises and increased productivity.VERICUT is also widely used in aerospace, automotive, mold manufacturing and other industries, its most important feature is the simulation of
various CNC systems, both simulation cutter location file, but also the NC program simulation CAD/CAM post-processing, the entire simulation verification process includes procedures, analysis, machine simulation, optimization and model output.
Punch with the complex cavity and runner as a processing object in this paper, it related to the roughing, sweeping and pocketing in CATIA , and generate NC-code ultimately. Then simulation on the machine in VERICUT.
