Problems solved by technology

In the existing technology, the CNC machine tool will start to move the tool to the processing position only after the tool accelerates to the target speed (the process of the tool moving to the processing position is called the lower tool), that is, during the process of tool acceleration , that is, before the tool accelerates to the target speed, the CNC machine tool does not move and is in a waiting state. This waiting time is wasted, thereby prolonging the processing time of the CNC machine tool and reducing the processing efficiency

Embodiment Construction

[0010] The invention will be described in detail below in conjunction with specific embodiments.

[0011] Since the cutting tool of the CNC machine tool is driven by the rotating shaft of the machine tool to rotate, the rotating speed of the cutting tool is the same as the rotating speed of the rotating speed, and the rotating speed here refers to the angular velocity. The angular velocity of the CNC lathe is controlled to lower the tool if the following conditions are met during the acceleration of the machine tool's rotating shaft:

[0012] The angular velocity of the rotating shaft reaches a preset rotational speed.

[0013] The rotating shaft continues to accelerate during the cutting process. As long as the preset rotational speed is appropriate, when the tool moves to the processing position, the rotational speed of the tool just reaches the target rotational speed, so the workpiece can be processed immediately. Of course, in order to prevent the tool from accelerating ...

Abstract

The invention provides a cutting control method for a CNC (Computer Numerical Control) machine tool and relates to the technical field of control on the CNC machine tool. Specifically, during the accelerating process of the cutter of the machine tool, when the accelerating time of the cutter reaches the preset time or the speed is accelerated to a preset rotating speed less than a target rotating speed, the machine tool acts and causes the cutter to start to move towards a processing position; when the cutter moves to the processing position, the rotating speed of the cutter reaches the target rotating speed; during the accelerating process of the cutter, when the cutter is accelerated to the preset rotating speed less than the target rotating speed, the CNC machine tool starts to cut; since the moving process of the cutter from an initial position to the processing device also costs time and the cutter is continuously accelerated during a cutting process, so that the cutting and the cutter acceleration are simultaneously performed, the time for waiting for the cutter acceleration is shortened, the processing time of the CNC machine tool is shortened then and the processing efficiency is increased.

Description

technical field [0001] The present invention relates to the technical field of control of CNC machine tools, in particular to a method for controlling the cutting of CNC machine tools. The method is completed by establishing a functional module framework and controlling a computer system by computer program instructions. These computer program instructions are stored in a computer-readable in the storage medium. Background technique [0002] The tool of a CNC machine tool (Computer numerical control, CNC machine tool) needs to be accelerated to a target speed before processing the workpiece. The tool of the CNC machine tool is fixed to the rotating shaft of the machine tool, and the rotating shaft drives the tool to rotate. In the existing technology, the CNC machine tool will start to move the tool to the processing position only after the tool accelerates to the target speed (the process of the tool moving to the processing position is called the lower tool), that is, duri...
