Document Type and Number:
WIPO Patent Application WO/2013/146545
Kind Code:
A1
Abstract:
A method for controlling a machine tool comprises: an attachment which includes a machine tool main body, a ram that is supported in a movable manner with respect to the machine tool main body, a main shaft that is supported in a drivable and rotatable manner by the ram, a driving shaft that can be attached to and detached from a tip end portion of the ram and rotates in response to the rotation of the main shaft, and a tool disposed on the driving shaft; and an NC device performing numerical control based on processing data, wherein the machine tool performs mechanical processing on a processing target. According to the method for controlling the machine tool, either one of the ram overhang amount and the ram feeding amount is decreased in a case where the stress related to the attachment is larger than the allowable stress of the attachment based on processing conditions consisting of the diameter of the tool, the depth of cut, and the feeding amount, and data consisting of the ram overhang amount, the shape of the attachment, and the material of the processing target.
