METHOD AND DEVICE FOR AUTOMATICALLY CONVERTING CORRECTION QUANTITY FOR EACH TOOL TYPE AT TOOL CHANGE

摘要

PURPOSE: To facilitate the programming and improve the productivity by providing a tool correction quantity setting means for replacing a tool correction quantity by use of the correction value when the insert position is differed. ;CONSTITUTION: When the automatic tool change command of an NC program is started, a tool type judging means judges the number and type such as a rotating tool 2 or a fixed tool of a command tool to be inserted to a tool reset. An inserting position judging means judges whether the insert position of the command tool is a first insert position or a second insert position. Then, a tool correction quantity setting means determines a tool correction quantity (X=A, Z=β), (X=α, Z=B) from the tool data on the basis of the judgments of the number and type of the command tool and the tool correction quantity, and converts the tool correction quantity by use of a correction value when the insert position is differed.;COPYRIGHT: (C)1994,JPO
