Utilizing CAEDOS to Program 2-Axis Contouring on Numerically Controlled Point to Point Milling Machines
Abstract
This Memorandum describes the manner in which a procedure (and software) for utilizing a numerically controlled point to point milling machine as a 2-axis contour milling machine was developed, demonstrated and implemented on CAEDOS. A point to point milling and drilling machine will move its table from one point to precisely another point, however, unless this is a straight X or Y axis move, it will not travel a straight line to get there. By contrast, a contour milling machine will move its table (and tool chuck, for 3-5 axis contouring) from one point to precisely another point, while moving in exactly a straight line. This requires more complicated algorithms in the machine controller's software, as well as precise coordination between the machine axis' movements, both of which are lacking in a point to point machine. The only numerically controlled machines Code 422 has are Pratt & Whitney point to point milling/drilling machines, built in 1968. In order to accommodate jobs that encompass milling anything other than either straight X or Y axis moves (i.e., angled or curved contours), the following effort was undertaken.
