摘要：外形和内腔均为偏心且内腔极其复杂的异形结构壳体零件，其铸件毛坯余量大且不均匀，材料去除量大，内腔干涉现象严重，给零件的加工定位装夹、编程和加工效率的提升带来挑战。基于UGCAM模块对内腔进行编程，采用加长杆直角铣头加工内腔，同时利用VERICUT模拟加工过程解决干涉问题，提高加工效率。

Abstract:For specialshaped shell parts with eccentric shape and inner cavity，extremely complex inner cavity，large and uneven blank allowance，large amount of material removal and serious interference of inner cavity bring great challenges to the part′s processing，positioning，clamping，programming and processing efficiency.The inner cavity is programmed based on UGCAM module，and the inner cavity is processed by rightangle milling head with elongated rod.At the same time，VERICUT is used to simulate the processing process to solve the interference problem，and the processing efficiency is improved.
