OPERATION LIMITING DEVICE FOR MACHINE TOOL

摘要

An operation limiting device applicable to a wide variety of machine tools and which improves the freedom of setting an operation limiting area. Two or three drive axes (Xa, Za) in different directions are designated from among a plurality of drive axes in the machine tool and the designated drive axes (Xa, Za) form the two or three dimensional coordinate system. An area (Ar) for limiting the operation of the mobile body is set in the two or three dimensional coordinate system. A drive axis (Xa) which is in operation is determined, and in the two or three coordinate system including the drive axis which is in operation the operation of the mobile body is limited when the mobile body enters into the limiting area (Ar).

1. An operation limiting device for a machine tool comprising:
a drive axis designating means for designating two or three drive axes in different directions among a plurality of drive axes of the machine tool; a coordinate system forming means for forming a two-dimensional coordinate system or a three-dimensional coordinate system by the designated two or three drive axes; a limiting area setting means for setting a limiting area to limit an operation of a mobile body in the two-dimensional coordinate system or the three-dimensional coordinate system; a determining means for determining a drive axis by which the mobile body is in operation; and a limiting means for limiting the operation of the mobile body when the mobile body enters into the limiting area in the two-dimensional coordinate system or the three-dimensional coordinate system including the drive axis by which the mobile body is in operation.
