| Research Abstract |
Complicated shape molds are generally processed by die-sinking EDM and then finished by hand lapping. In order to enhance the efficiency and accuracy in manufacturing metal molds, a lapping machine, which can apply three-dimensional tool motions to a lapping tool, was developed and its fundamental lapping performance was investigated. As a result, the following things became clear. (1) Larger form collapse arises in a lapped surface by three-dimensional figure-8 tool motion while good surface roughness is obtained. (2) Form collapse of a lapped surface becomes small when circular tool motion with a central axis parallel to the work feed direction is used.
