Abstract：

In order to solve the problem of low efficiency on creating trimmed inserts shape-fitting surface of cutting surface and clearance surface, a partial-profile splitting method was presented to trim insert by the partial profile at the insert location, and the data searching process for the whole profile was omitted. Therefore, the time-consume problem of whole surface trimming method was solved, and the design efficiency of single insert was improved by 100%. At the same time, a segmented-sweeping method was put forward to improve the shape-fitting surface quality of non-shape-fitting trimming insert. Furthermore, the curvature upheaval area was recognized by the tag method, and the curves were divided into several segments to sew the corresponding sweeping surfaces. Thus, the local distortions of surface produced by the integral sweep method were solved, and the effectiveness of two methods was analyzed by examples to make comparisons of their efficiency and quality.
