Problems solved by technology

[0004] In the prior art, when the tool touches the workpiece on the CNC lathe for processing such as threading, the spindle speed will drop due to the cutting force, which will cause the workpiece rotation speed to drop
However, the kinematic relationship between the tool and the workpiece is predetermined, and the drop in the rotational speed of the workpiece will affect the machining accuracy of the workpiece

Abstract

The embodiment of the invention discloses a method, device, system and storage medium for compensating the rotation speed of a lathe workpiece. The method includes: reading the machining position of the tool and the actual rotational speed of the workpiece; determining the first drop compensation amount related to the predetermined rotational speed setting value of the workpiece based on the machining position of the tool; A second drop compensation amount of the actual rotation speed; feedforward compensation of the rotation speed of the workpiece based on the second drop compensation amount. The embodiment of the present invention compensates the drop of the workpiece rotation speed in advance, thereby improving the machining accuracy.

Description

technical field [0001] The invention relates to the technical field of lathe control, in particular to a method, device, system and storage medium for compensating the rotation speed of a lathe workpiece. Background technique [0002] Numerical control technology is also called computer numerical control (CNC, Computerized Numerical Control) technology, which is a technology that uses a computer to realize digital program control. In numerical control technology, the pre-stored control program is used to implement the sequential logic control function of the motion trajectory of the equipment and the operation of peripherals. Since the computer is used to replace the original numerical control device composed of hardware logic circuits, the realization of various control functions such as storage, processing, calculation, and logical judgment of input operation instructions can be completed through computer software, and the microscopic instructions generated by processing a...
