Abstract:
A table (27) holding a work (28) is controlled through servomotors (22, 23) by position control means (10a) in a CNC device (10). A predetermined time before the positioning of the table (27) is completed, press action control means (10d) in the CNC device (10) operates a servomotor (21) to allow a press tool (26) to start approaching the work (28). Thereafter, the press tool (26) is controlled on the basis of action data stored in press action storing means (10c) in the CNC device (10).
