METHOD OF TRIAL CUTTING

Title:

METHOD OF TRIAL CUTTING

Document Type and Number:

WIPO Patent Application WO/1993/009912

Kind Code:

A1

Abstract:

A method of trial cutting, wherein stopping and restarting of trial cutting work, repeated operations of trial cutting work on a desirable portion and correcting work for a processing program can be easily performed. By providing speed increasing and decreasing keys K3, K4 for continuously changing a main shaft rotation speed R1 and speed increasing and decreasing keys K1, K2 for continuously changing a tool feed speed R2 on CRT, MDI (4) of a numerically controlled machine, whereby a main shaft rotation speed R1 and a tool feed speed R2 can be freely changed regardless of whether or not a main shaft rotation speed R1 and a tool feed speed R2 are specified by a processing program in a RAM 3, and optimal main shaft rotation speed R1 and tool feed speed R2 are determined while the cutting work is performed on the basis of a processing profile given by the processing program in the RAM 3. Since there is no need for determining optimal cutting conditions by changing a main shaft rotation speed and a tool feed speed by correcting the processing program for each processing unlike the prior art, optimal cutting conditions can be easily obtained within a short period of time.
