| Research Abstract |
This report deals with the fundamental study of high-accurate and high-efficient machining method for thin wall parts of honeycomb shape workpiece by twin spindle with parallel tools.
The main results are as follows.
(1) The new cutting method and cutting mechanism of high-accurate and high-effective for thin wall shape workpiece are proposed.
(2) The attachment of twin spindle and one set of parallel milling tools are designed and produced by way of trial. And several cutting tests are performed.
(3) The cutting force acting on the workpiece in the normal direction decreaces drasticaly in case of machining by using the twin spindle attachment. But the cutting foece in feed and axial directions are increased about twice respectively.
(4) The machining error of the thin wall shape workpiece decreases very much by using the twin spindle attachiment, because of avoidance of workpiece deflection by the normal cutting force.
(5) Calculated values of machining error by FEM analysis almost coincide with the experimental values changing by the cutting position and sequence of machining ; thus, the appropriateness of the meshed elements and the calculation method for the nodal load are verified.
