Abstract : The APT (Automatically Programmed Tooling) system provides for the software description of geometric forms, the delineation of a tool path, and, for output, discrete positioning information on punched paper tape for use by a numerically controlled machine. The CROSEC (Mod 1) program, described in the report, provides a means of extending the use of the canonical forms of the plane surfaces defined by the programmer in the part program by providing a plotting capability in which the lines in intersection, within specified limits, between a cross-sectional plane and all other defined planes are shown. A visualization of the initial plane framework on which the cutting is to be performed is thereby provided. The cross sectional plane and its dimensional limits are controlled by one plane definition and two point definitions. The plot is supplemented by printer output that aids in the interpretation of the plot. The program is written in the framework of the CDC 3800 APT 2.1 configuration. No additional program overlays or segments are necessary. The report contains a discussion of the method used, subroutine descriptions, listings and flow-charts, implementation aids, and a sample run. (Author)
