一、陶瓷精密切削法分析陶瓷的精密切削法是通过刀具的尖端将陶瓷有规则,一点一点地不断产生崩裂的切削方法,具体如下: 1.利用脉冲切削波形精密切削陶瓷利用作用时间短的脉冲状切削力波形,使陶瓷在刀具的刀尖附近产生崩裂。其金刚石车刀以频率f、振幅a在切削方向进行超声波振动,通过振动切削来作用于陶瓷。由于脉冲切削力波形的作用,使得在车床主轴卡盘上所夹持的陶瓷工件吃刀分力方向的弹簧常数K提高T/tc倍,从而可取得刚性化效果。 2.用间断脉冲波形切削力精密切削陶瓷根据振动切削,使间断脉冲切削力波形产生作用进行重叠振动切削。这种间断的脉
First, the ceramic precision cutting analysis of precision ceramic cutting method is by cutting the tip of the ceramic will have a regular, one by one continue to produce crack cutting method, as follows: 1. The use of pulse cutting waveform precision cutting short use of ceramic time Of the pulse-like cutting force waveform, so that ceramic cutting edge near the knife cracks. The diamond turning tool vibrates with ultrasonic waves in the cutting direction at the frequency f and the amplitude a, and acts on the ceramic through vibration cutting. Due to the waveform of the pulse force, the spring constant K in the direction of component force of the ceramic workpiece held on the lathe spindle chuck is increased by T / tc, so that the rigidity effect can be obtained. 2. Intermittent pulse waveform cutting force Precision cutting ceramic according to vibration cutting, so that the intermittent pulse force cutting waveform effect of overlapping vibration cutting. This intermittent pulse
