Title:
THREE-DIMENSIONAL OFFSET TYPE CNC LASER MACHINING APPARATUS
Document Type and Number:
WIPO Patent Application WO/1994/023885
Kind Code:
A1
Abstract:
This invention provides a three-dimensional offset type CNC laser machining apparatus which can effect an operation for fixing the distal end without changing parameters and without returning to zero by a manual intervention when a head is changed at an intermediate stage of machining. This apparatus comprises a three-dimensional tool length correction instruction portion (11) for instructing tool length correction at the time of the change of a nozzle head, first correction means (13) for effecting correction to move the distal end position of the nozzle head as a machining program point to a program point before the change in response to the tool length correction instruction and second correction means (14) for correcting change components of three orthogonal axes that change with the change of a rotating angle when the distal end position is moved.
