<p>PURPOSE:To program an objective position which once goes back and forward again on the way of processing easily, by providing a machine coordinate counter and a cursor coordinate counter. CONSTITUTION:A pulse outputted from a position detector 1 is inputted to two coordinate counters, a machine coordinate counter 3 and a cursor coordinate counter 4, at the same time and revises the present position. The counter 4 can write arbitrary data by a central processing unit 13. When a cut-feed is interrupted due to external causes, the cursor coordinate is reset at the interruption, the returned coordinate is programmed with the machine coordinate and advanced with the cursor coordinate. Thus, the home position, processing start, intermediate return position and processing end position are included in a machine coordinate program and the steps are taken as the cursor coordinate.</p> |
