主电动机调频控制。
采用机床主电动机功率法和声发射(AE)法来获取切削过程中发出的刀具磨损和破损信号,建立了刀具状态试验系统。
Experiments were implemented to obtain the motor power and AE signals under different cutting parameter condition(cutting velocity, feed velocity and cutting depth), tool wear and breakage conditions.
镗床主传动系统是用来实现镗床主运动的,它将主电动机的原动力变成可供主轴上刀具切削加工的切削力矩和切削速度。
The system of boring main driving is used to achieve the main movement boring machine, main Motor will become the driving force on the tool spindle machining cutting torque and the cutting speed.
