Abstract： In order to solve the problems of the slow speed of cutting and low utilization  rate of current domestic leather cutting machine，the NC cutting technology was investigated，and the control system design program of computer leather cutting machine was proposed of which the core is the industrial PC with a motion control card. Meanwhile，Visual C++ tool was used to develop the control software based on Windows XP. In the software，the functions of path optimization and pattern typesetting were realized with the use of a variety of computer graphics algorithms and combining with the features of pattern data in PC. The results show that using the cutting machine， the quality and efficiency of cutting have been improved.
