Device and method for measuring flank wear of ball end milling cutter

Abstract

The invention relates to a device and method for measuring flank wear of a ball end milling cutter. With the progress of the machine manufacturing technology, in the milling process, the requirementsfor the machining precision of workpieces are higher increasingly. At the same time, due to the special double helix structure of the ball end milling cutter, it is necessary to study flank wear of the milling cutter so as to improve the surface machining quality. The device for measuring flank wear of the ball end milling cutter comprises two parts of hardware and software, wherein the hardware comprises a machining device (1), a double-reflection device (2) and a tablet computer (3), wherein the machining device comprises a machine frame (4). The machine frame is connected with a main shaft(5), and the main shaft is connected with a milling cutter (6), and the double-reflection device comprises a three-coordinate measuring instrument (7) and a double-reflection plate (8). The three-coordinate measuring instrument is connected with the tablet computer, and three-coordinate measuring software, tool wear measurement software and a windows system are installed on the tablet computer. The device and method are used for accurate measurement of flank wear when the milling cutter conducts milling.

Description

technical field [0001] The invention relates to a measuring device and a measuring method for the flank wear of a ball-end milling cutter, in particular to a measuring method for the flank wear of a milling cutter in the milling process using a ball-end milling cutter, and belongs to the technical field of mechanical cutting. Background technique [0002] With the continuous development of mechanical manufacturing technology, the complexity of the workpiece is gradually increasing in metal cutting. There are a large number of complex structures such as grooves, rounded corners, and convex-concaves in the mold during processing. At the same time, overall wear and damage will occur during the processing. Severe tool wear will also cause cutting chatter, which will affect milling accuracy and tool life. . At present, the research on tool wear detection technology is mainly concentrated in the field of turning, but there are not many researches in the field of milling. Due to t...

There are a large number of complex structures such as grooves, rounded corners, and convex-concaves in the mold during processing. At the same time, overall wear and damage will occur during the processing. Severe tool wear will also cause cutting chatter, which will affect milling accuracy and tool life.

At present, the research on tool wear detection technology is mainly concentrated in the field of turning, but there are not many researches in the field of milling. Due to the special double helix structure of the ball nose milling cutter, the flank structure is more complicated, so the measurement accuracy cannot be guaranteed. , for further study
