ABSTRACT:
Interference checking device including: a modeling database that stores data for three-dimensional modeling of tools, workpieces, and machine-tool constituting structures; an interference data memory for storing interference data defining inter-component interference relationships among the tool, the workpiece, and the structures; and an interference checking processor that, based on structure movement commands sent from a program analyzer for the machine tool, and on data stored in the modeling database and interference data memory, determines whether the tool, the workpiece, and the structures will interfere with each other. Movement commands in a block at least one block succeeding the block being executed in order to control the drive mechanisms that move the structures are sent from the program analyzer to the interference checking processor.
