Simulation Of Multi-axis Machining Research Based On VERICUT

It’s relatively complex for calculating the location of tool center coordinates and prone toproduce over-cutting, under-cutting or collisions for the reason that multi-axis machiningincreased rotational movement. Multi-axis machining is usually applied to typical andcomplex parts such as single-blade impeller parts, integral impeller parts or spatial cam.Generally, three-axis machining and toolpath simulation could be verified directly throughCAM software simulation function. However, it will bring about great collision risks WhenNC program of multi-axis machining can not be validated effectively by CAM software.There are many advantages when using VERICUT software such as saving verification time,simulating machining process as real, avoiding over-cutting, under-cutting or collisions,protecting machines and cutting tools, eliminating potential risks, replacing trial-cutting,extending tool life at the greatest degree by optimizing NC programs, improving processingefficiency and quality, so we can guide production practice in this way.This thesis is mainly aiming at multi-axis machining typical parts such as integralimpeller and cylindrical cam simulation study. Taking cylindrical cam as example, we can getsimulation and optimization of the whole process through analyzing technical requirementscomprehensively, planning a rational machining technology program and design, creatingmodels of machines, tools and workpiece, importing post-processed program to VERICUT.
