等离子熔积与激光切割复合直接制造CAM软件研究

针对等离子熔积制造易产生侧表面阶梯效应，导致精度和表面质量不高的问题，提出将等离子熔积和激光轮廓切割复合以改善熔积成形件表面质量的方法。开发了等离子熔积激光切割复合直接制造CAM软件，在软件中提出了一种带法向的分层切片方式，对等离子熔积、激光轮廓切割的轨迹分别进行了规划，产生相应的NC代码，并对2个单工序NC代码进行了复合，以达到等离子熔积和激光轮廓切割工艺上复合的目的。

Study on the CAM Software of Plasma Deposition Directly Manufacturing Combined with Laser Cutting

To solve the problem of low accuracy and surface quality ca us ed by the side surface stair case effect during the course of plasma deposition manufacturing,the paper brings forth a new method combining plasma deposition m anufacturing with laser contour cutting so as to improve surface quality of the parts.The CAM software of plasma deposition directly manufacturing combined with laser cutting is developed.In the software,a new model slicing method with norm al is presented,machining path of plasma deposition and laser contour cutting ar e planned and relevant NC codes are automatically generated or recombined so as to combine two processes.
