PRESS WORKING CONTROL SYSTEM

摘要

PROBLEM TO BE SOLVED: To control bending press working without repeating the detection of temperature by a temperature detector and the correction of working data by a working data correction part until a target time. SOLUTION: When the variation of a temperature distribution pattern at an intermediate time T2 from the pattern at a predetermined reference time T1 exceeds a given variation, a temperature distribution pattern at the target time T3 is calculated. A temperature distribution pattern identical or similar to the temperature distribution pattern at the target time T3 is selected from the patterns in a correction table 45, and the working data are corrected based on a correction index corresponding to the selected temperature distribution pattern.
