In the processing process, the process parameters are set as: N=1000×V/(3.14×D).

Spindle speed (RPM /min)V: cutting speed (m/min)

Setting of feed speed when cutting tool diameter (mm) :

F=N×M×FnF: feed speed (mm/min)M: number of tool edges Fn: cutting amount of tool (mm/ revolution)

The cutting amount of each blade is set: Fn=Z× Fzz: the number of blades Fz: the cutting amount of each blade of CNC machine tool brand blade (mm/ turn)

6. Boot processing.

At the beginning of each procedure, it must be carefully checked that the tools used are the same as those specified in the instructions. When cutting feed speed should be transferred to the minimum, single section, rapid positioning, the cutting, feed must concentrate on hand should immediately stop the knife, pay attention to the CNC machine tool is introduced when the knife is going to watch the moving direction of cutting tool, to ensure safety of feed, and then slowly increase to feed speed is appropriate, cutting tool and workpiece at the same time to add the cooling fluid or air cooling. When starting rough machining, it should not be too far away from the control panel. If there is any abnormal phenomenon, it should be stopped and checked in time.
