Design method of discrete edge end mill with variable chip dividing groove parameters

The invention discloses a discrete edge end mill design method with variable chip dividing groove parameters. A discrete edge end mill suitable for deep cavity machining is designed based on three-dimensional modeling software. The variable parameters in the design method of the discrete edge end mill with the variable chip dividing groove parameters comprise chip dividing groove distribution position changes and chip dividing groove structure parameter changes. The influence of the chip dividing grooves on the cutter performance is considered, the dispersion concept is introduced, and the influence rule of the number of the chip dividing grooves on the cutting length is quantified. According to the discrete edge end mill with variable chip dividing groove parameters, the spectral characteristic in the milling process can be changed, vibration in the machining process is restrained, the chip dividing grooves in the circumferential edges can reduce the cutting length, and the heat dissipation performance of th
