Title:
DETERMINING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/193768
Kind Code:
A1
Abstract:
The present invention quickly determines factors such as shape errors and machined surface defects by comparing the machined surface shape calculated on the basis of the actual motor position, and the machined surface shape obtained by actually measuring the machined surface of a machined workpiece. This determining system is equipped with: a motor position acquisition unit for acquiring the actual position of a motor for driving the drive shaft of a machine tool; a tool information acquisition unit for acquiring tool information which includes the machine tool driveshaft configuration, the instrument shape and the unmachined workpiece shape; a motor position machined surface calculation unit for calculating the shape of the machined surface of the machined workpiece on the basis of the tool information and the actual position of the motor; an actual machined surface acquisition unit for acquiring the shape of the machined surface of an actually machined workpiece; and a machined surface analysis unit for comparing a first correlation, which is the correlation between the shape of the machined surface calculated by the motor position machined surface calculation unit and the shape of the machined surface acquired by the actual machined surface acquisition unit.
