摘要 A maximum undeformed chip thickness, a cutting arc length or an engage angle, and an active angle for each tooth of the end mill are calculated when a ball end mill is used in machining, or the maximum undeformed chip thickness, the cutting arc length or the engage angle, and an axial depth of cut for each tooth of the end mill are calculated when a straight end mill is used in machining. Then, the estimated value of the cutting force Fxy or Fxyz in each portion of the tool path is calculated on the basis of a response surface whose explanation variables are composed of the above-mentioned calculated values, whereby the feed rate contained in an equation for the maximum undeformed chip thickness tm is determined to maintain the obtained estimated value of the cutting force Fxy or Fxyz at an appropriate value. This permits automatic generation of an NC program for setting an appropriate feed rate along the entire tool path of the end mill in advance as a combination with the tool path and thereby achieving a machining situation in which the cutting force is maintained at constant.
