THE PATH LAYOUT METHOD OF DRILLING HOLESBASED ON UNIFORM DISTRIBUTION AND ITSAPPLICATION

摘要

In order to resolve the problem of ceramic honeycombrnextrusion die in use process, especially the problem ofrndifferent extrusion speed even curving due to the change ofrnhole's diameter, a new kind of method for generating NCrndrilling path has been proposed based on uniform distribution.rnIn drilling hole process, the drilled holes keep to uniformrndistribution always in the whole area of holes. With the helprnof manufacturing system engineering, in the use point of view,rnthe die extrusion's problem caused by drill bit wearing inrndiameter's direction has been compensated. The uniformity ofrnthe drilled holes as the method is tested with the χ2 testrnmethod. The test result indicates that the uniformity level isrnprominence. From the simulation result and actual usage, thernproblem of extrusion die caused by drill bit wearing can bernresolved effectively. The method is an effective method forrngenerating NC drilling path. The performance of ceramicrnhoneycomb extrusion die can be improved.
