Description

Technical Field

[0001] The present invention belongs to the technical field of metal processing, and particularly relates to an intelligent adaptive cutting device for metal processing. Background Art

[0002] Metal processing cutting is a processing method that removes excess metal from a workpiece by using the relative movement between a cutting tool and the workpiece. The cutting process is widely used in the precision processing of various metals and is the basis for manufacturing complex-shaped and high-precision components.

[0003] The Chinese patent with the application number CN201810159197.1 and the publication number CN108538718B discloses a cutting device. During the cutting of a workpiece, an operator can easily determine the part where the load current value of the spindle equipped with the cutting tool becomes high. The cutting device includes: a spindle that is rotationally driven; and a cutting tool that is mounted at the front end of the spindle and cuts the workpiece held by a chuck table. The cutting device performs cutting on the workpiece along a machining predetermined line. Among them, the cutting device includes: a load current value detection unit that detects the load current value of the spindle during cutting; and a display unit that displays the load current value detected by the load current value detection unit. The machining predetermined line and the load current value of the spindle when machining the machining predetermined line are correspondingly displayed on the display unit.

[0004] The Chinese patent with the application number CN201810047363.9 and the publication number CN108335976B discloses a cutting device that can eliminate unnecessary removal during the dressing of a cutting tool. A cutting device, wherein the cutting device includes: a cutting assembly having a cutting tool with a cutting edge for cutting a dressing plate; an elastic wave detection sensor disposed in the cutting assembly for detecting elastic waves generated when the dressing plate is cut by the cutting tool; and a control assembly. The control assembly has a storage unit. When dressing is performed by cutting the dressing plate with the cutting tool, the output signal of the elastic wave detection sensor changes as the cutting tool is sharpened. The storage unit pre-stores the value of the output signal of the elastic wave detection sensor when the dressing is completed after being sharpened as a threshold value. After the output signal from the elastic wave detection sensor reaches this threshold value, the cutting is stopped and the dressing is ended.
