摘要： Design parameters of a cutting tool (1), which include the feed speed (f), the cutting depth (da) in an axial direction, the cutting depth (dr) in a radial direction, and the cutting speed (v), are used to calculate the deflection amount (±) of the cutting tool (1). It is determined whether chatter vibration of the cutting tool (1) will occur, on the basis of the deflection amount (±) and a prescribed threshold value (²), and the maximum cutting thickness (Ctmax) is calculated on the basis of the determination result. The cutting temperature (t) is calculated from the maximum cutting thickness (Ctmax) and the cutting speed (v), and it is determined whether the tool life will be fulfilled, on the basis of the cutting temperature (t) and a prescribed threshold value (³). The cutting efficiency (e) is calculated on the basis of the determination result, and the calculated cutting efficiency (e) is compared with previously stored cutting-efficiency data, and, in cases when the calculated cutting efficiency (e) is the maximum value in the data, the design parameters are set as cutting conditions.

摘要： Design parameters of a cutting tool (1), which include the feed speed (f), the cutting depth (da) in an axial direction, the cutting depth (dr) in a radial direction, and the cutting speed (v), are used to calculate the deflection amount (α) of the cutting tool (1). It is determined whether chatter vibration of the cutting tool (1) will occur, on the basis of the deflection amount (α) and a prescribed threshold value (β), and the maximum cutting thickness (Ctmax) is calculated on the basis of the determination result. The cutting temperature (t) is calculated from the maximum cutting thickness (Ctmax) and the cutting speed (v), and it is determined whether the tool life will be fulfilled, on the basis of the cutting temperature (t) and a prescribed threshold value (γ). The cutting efficiency (e) is calculated on the basis of the determination result, and the calculated cutting efficiency (e) is compared with previously stored cutting-efficiency data, and, in cases when the calculated cutting efficiency (e) is the maximum value in the data, the design parameters are set as cutting conditions.
