Tool Length Setting Method In A CNC Milling Machine And Storage Medium

摘要

The present invention relates to a method for setting a tool length of a CNC milling machine to a minimum, but does not cause a collision, and a recording medium recording a program code thereof. To this end, in the CNC milling machine, a data setting step (S10) of setting data relating to the tool 30, the to-be-deleted model and the machining path; A simulation step (S20) of virtually simulating cutting using the set data; An estimating step (S30) of calculating a collision boundary shape (40) from the geometric data around the tool (30) during the simulation; A display step (S40) of displaying the calculated collision boundary shape (40); And a setting step (S50) of setting a length of an actual tool based on the collision boundary shape 40 displayed. It includes.
