The invention discloses a contact feedback automatic measuring method and system of a numerical control machine tool and a storage medium. The contact feedback automatic measuring method of the numerical control machine tool comprises the following steps: a feeding path of a measuring mechanism is obtained; a measuring contact of the measuring mechanism is controlled to contact with multiple acquiring points of workpieces according to the feeding path for conduction with a contact feedback circuit by multiple times; multiple electric signals generated by the contact feedback circuit are received, and multiple position coordinate information corresponding to the measuring contact is recorded; and measuring information for cutter alignment is determined according to the multiple position coordinate information. Through measurement of the contact between the measuring contact and the workpieces, the contact feedback circuit can be conducted to automatically obtain the corresponding electric signals and the position coordinate information; and the measuring information for cutter alignment can be automatically calculated according to the multiple position coordinate information withoutneeding manual complicated calculation, so that the method has the advantages of convenience to operate and low cost.
Description
technical field [0001] The invention relates to the technical field of mechanical processing, numerical control machine tools and measuring instruments, in particular to a contact feedback automatic measuring method, system and storage medium of a numerical control machine tool. Background technique [0002] Generally, CNC machine tools need to perform tool setting and edge finding measurement processes to determine the workpiece coordinate system before machining. There are many measurement methods used in actual processing, such as trial cutting tool setting and edge finder edge finding. The method is simple It is convenient, but it needs to be done manually, and it is easy to leave contact marks on the surface of the workpiece, and the accuracy of tool setting is low; or for tool setting outside the machine, it is necessary to use products such as tool setting instruments for off-machine measurement, and re-measurement during processing requires Stopping and clamping, the...
