Title:
NUMERICAL VALUE CONTROL DEVICE, NUMERICAL VALUE CONTROL SYSTEM, CONTROL METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2024/070400
Kind Code:
A1
Abstract:
Provided are a numerical value control device, a numerical value control system, a control method, and a program, with which a primary shaft can be retracted to an appropriate position when executing magazine rotation correction. In a state in which a primary shaft is stopped at a point M4 on a tool exchange path 52, a CPU determines whether there is a rotation deviation in the magazine in order to restore the position of the primary shaft in a machining region. If it is determined that there is a rotation deviation, the CPU detects a Z axis of the primary shaft, and determines whether the detected position of the Z axis is at a Z axis ATC origin point. If the detected position is not at the Z axis ATC origin point, there is a possibility that the primary shaft is positioned within a magazine rotation region. In this case, the CPU retracts the primary shaft to the Z axis ATC origin point, and requests an operation or task for executing rotation correction to return the magazine to a reference position. Once the rotation correction has been performed, the CPU moves the primary shaft toward the machining region along a tool exchange path 52, 51.
