Eleven operations on a set of two-dimensional domains are defined to grasp and handle clearly the varied types of collision problems in process planning of NC-lathe operations. One of the most essential concepts for the solution of dynamic collision problems is "Interference Domain" determined by a wonk-contour and a tool-contour. When the tip of the tool is located in the interference domain, the tool must collide against the workpiece. Using inversion and envelope operations, an algorithm named "Inversed Template Method" is presented to compute an interference contour easily from complicated contours of work and tool. A computer program is coded as a set of subroutines executing the operations by which several typical collision problems in lathe operations are solved to show the effectiveness of the domain operations.
