| Outline of Final Research Achievements |
Estimation of instantaneous cutting force in machining process requires several kinds of geometric information. These consist mainly of cutter locations in tool path and initial shape of stock workpiece. Conventionally, the initial shape of workpiece for cutting force simulation has been generated as CAD model from computer simulation.
In this research, we propose a new method to measure the initial shape of the workpiece with non-contact measuring process by light cutting method. In the proposed method, for each cutter location, removal area by cutting edge is estimated from the measured point cloud data. By applying the proposed method, it is possible to estimate the cutting force on machine tool in the finishing process for stock shape of workpiece formed by casting and additive manufacturing.
