Title:
NUMERICAL CONTROLLER
Document Type and Number:
Japanese Patent JP3563191
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To enable the minute setting of interference object, an exact interference check and an interference evasion by providing an interference object moving location calculation means, at interference decision area calculation means and an interference decision means deciding the presence or absence of an interference based on the interference decision area set by the interference decision area calculation means.
SOLUTION: The stereoscopic definition data 22 stored in a memory 3 is the input data defining the interference object to be used for the calculation for an interference check or an interference evasion. An interference object moving location calculation means 24C calculates the moving location of the interference object after the axial moving amount output accompanying an interpolation processing from the moving amount of the location of the present interference object and the axis moving the interference object. An interference decision area calculation means 24 obtains the interference decision area of the interference object by calculating an interference decision stereo showing the area with which the stereo composing the interference object from the location before the interpolation processing to the location after the interpolation processing is possible to interfer, in the stereo composing the interference object. An interference decision means 25 decides the presence or absence of the interference of the interference decision stereo.
