Machining error determination for 3-axis milling of free form surfaces

Abstract

The use of free form surfaces in mechanical engineering is accelerating by functional and esthetics demands. Use of CAD/CAM software is a must because analytical description of a given surface and tool path generation. There are many methods for tool path optimization, one of them is federate scheduling which is described in this paper. The machined part which is manufactured according to optimization algorithm was measured on the optical scanner. Paper presents description of developed CAD/CAM application in Matlabsoftware and performed experiment for determining the cutting forces in freeform surfaces machining. At the end of paper is given map of deviations determined by Matlab software for one of machined surface from point cloud obtained using optical scanner.
