摘要
采用基于应变片式测力仪、PCI9118数据采集卡及Visual Basic编程语言的车削力测量系统,实现了对采集来的切削数据的向间标定系数的基于一元线性回归方程的计算,并分析了数据的相关性;通过实际加工测量,利用标定系数得到了实际切削力的大小,求出了3个方向的关于进给量和背吃刀量的切削力经验公式,为车削加工提供了参考数据。
By using the cutting force measuring system based on strain gage type cutting dynamometer, PCI 9118 data acquisition card and Visual Basic programming language, this paper realizes the monadic linear regression equation based calculation of the interphase calibration coefficient of the collected cutting data, and analyzes the correlation of the data,and th ough the actual processing measurement, obtains the size of the actual cutting force by using the calibration coefficient, establishes the cutting force experience formulas of the cutting feed and back cutting depth on the three directions,providing the reference data for the lathe work.
