Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the examples, but the present examples are not intended to limit the present invention, and all similar methods and similar changes of the present invention should be included in the protection scope of the present invention.

[0031] In the process of establishing the cutting force model, the non-equal shear zone model is used to calculate the cutting force under the action of the sharp diamond tool generated by the formation of chips, and then the plowing force caused by the blunt cutting edge is calculated. The comprehensive superposition of the two can get the cutting force when considering the blunt cutting edge.

[0032] In the process of chip formation, the force required for shear slip is transmitted by the rake face of the diamond tool and through the chips. Since the chips flow out along the rake face at a certain speed, the cutting force should satisfy The friction condition o...

Abstract

The invention discloses a diamond cutter abrasion monitoring method based on a cutting force model. The diamond cutter abrasion monitoring method is used for conducting real-time online monitoring on the abrasion loss of a cutting tool. The diamond cutter abrasion monitoring method is characterized by comprising the steps that 1, cutting force caused by chip forming under the action of a sharp diamond cutter in the cutting process is calculated by means of a non-equant shearing region model; 2, plowing force caused by cutting edge roundness in the cutting process is calculated; 3, diamond cutter cutting force is obtained according to the determined cutting force under the action of the sharp diamond cutter and the determined plowing force caused by cutting edge roundness; 4, a diamond cutter abrasion monitoring model is established according to the obtained diamond cutter cutting force, and therefore real-time monitoring on diamond cutter abrasion is achieved. By means of the diamond cutter abrasion monitoring method based on the cutting force model, the diamond cutter abrasion state can be accurately represented, monitoring on the diamond cutter abrasion can be achieved by monitoring the cutting force, and therefore real-time online and accurate monitoring of the diamond cutter abrasion is achieved.

Description

technical field [0001] The invention belongs to the field of tool wear monitoring and relates to a diamond tool wear monitoring method based on a cutting force model. Background technique [0002] During the cutting process of the workpiece, the tool will be worn, and the wear of the tool will cause the geometric shape of the tool to change, so that the workpiece will have a dimensional deviation and affect the processing quality of the workpiece. In order to avoid excessive deviation of the workpiece and improve the processing quality, it is necessary to monitor the wear of the tool, and determine whether to change the tool according to the monitoring results. [0003] Diamond cutting tools are widely used in actual production. The commonly used method of monitoring diamond tool wear is the direct monitoring method, which mainly detects by directly measuring the average wear amount of the middle part of the flank wear zone. Since the direct monitoring method needs to cont...
