PROCESSING FINISH TIME PREDICTING NUMERICAL CONTROL APPARATUS. |
摘要 |
<p>A reference processing speed (Vi) and an offset amount for each processing operation are determined on the basis of a set material and thickness of a work, a set diameter of a wire electrode and a set number of processing operations and with reference to a processing condition table for a nonvolatile memory (2). A total length (Di) of a processing path for each processing operation is determined on the basis of a processing movement command given by a processing program, the above-mentioned diameter of a wire electrode and offset amount. The time (T0) required to carry out the whole of a process is determined by integrating all of the time (Ti) required for a process with respect to each processing operation which is obtained by dividing the total length (Di) of a processing path for each processing operation by the reference processing speed (Vi) for each processing operation. The time (T0) required for a process is added to the present time (Tn) read from a timepiece (3), and the result is displayed on a CRT of a CRT/MDI (10), whereby an operator is informed on the estimated processing finish time (these operations are carried out in S1-S12). <IMAGE></p> |
