Abstract

PURPOSE:To enable automatic exchange of cutters at a proper timing by providing a cutter change means which changes the cutters when the movement of a machine reaches a specified value as determined based on the detection results of a position detector. CONSTITUTION:As the movement of a cutter 23 exceeds a specified value, a command of a controller 1 stops the operation of a profiling computation circuit 11. Detection results (efg) of position detectors 15-17 are memoriezed into a memory 12. The controller 1 determines the movement in the direction of X, Y or Z axis required for arranging the cutter 23 at a specified position within an automatic cutter changing mechanism 18 on a machining table 25. A finishing signal is applied to the controller 1 when it is detected that a cutter head 22 moves by a movement value as designated based on detection results (efg) of the detectors 15-17. The controller 1 applies a cutter change command (d) to an automatic cutter change mechanism 18 through an output unit 4 to change cutters.

に入れることは困難であった。Conventional technology and problems A copying machine processes a workpiece into the same shape as the model by moving a tracer head that traces the model surface and a cutter head that is attached to a cutter that cuts the workpiece in an integrated manner. However, since machining is normally performed continuously over a long period of time, the cutter may wear out during copying and machining accuracy may deteriorate. Conventionally, in order to prevent this kind of thing, the operator constantly monitored the machining process and replaced the cutter with a new one when the cutter became worn and became difficult to cut. However, since this method replaces the cutter based on the operator's judgment, it not only puts a burden on the operator, but also has the drawbacks of making it difficult to replace the cutter at an appropriate time. In addition, in order to eliminate the above-mentioned drawbacks, it may be possible to include a command to replace the cutter in the profiling program so that the cutter is replaced automatically. This is different from a numerically controlled machining program in which commands are lined up, and because a single command causes long machining to be performed, it is difficult to include a cutter replacement command in the program.
