PURPOSE:To improve the processing efficiency by detecting the cutting load applied to a main or drive shaft to obtain the cutting start position and then correcting and editing automatically the rapid traverse of a program and the length of a cutting feed block. CONSTITUTION:When a tool has contact with an object to be processed, the starting point of the present block is shortened to the present position with the preceding block extended by an amount equal to the shortened value of the present block as long as the preceding block is rapidly traversed at a contact point. Otherwise a rapid traverse block equivalent to said shortened value is added between the preceding block and the present block if the preceding block is equal to a cutting block. When a block is added, a processing program memory area is extended and the address data on an address data memory area is replaced. When the tool is detached from the object to be processed, a rapid traverse block is put between the present block and the next block or the present cutting feed block is shortened with the starting point to the next rapid traverse block extended up to the present position. Thus a processing program is automatically corrected and edited to reduce an air cutting part. |
