Abstract:

In a method of tool selection control for a punch press machine equipped with a multi-tool holder, a tool selection instruction (1) consisting of 4-digit T codes such as (T1101) associated with a first punch tool (42a) of the multi-holder (42) is read from a machining program, and a holder designation code (T11XX) for designating the multi-tool holder provided to a magazine (4), which consists of the upper two digits of the T code, is converted to a target rotation position of the magazine by a first angle parameter (2). A tool designation code (TXX01) for designating a first punch tool fitted to the designated multi-tool holder, which consists of the lower two bits of the T code, is converted to a target rotation position of the designated multi-tool holder by a second angle parameter (3). The magazine and each of the designated multi-tool holders are rotated round their axes of rotation (T axis or C axis) and are positioned to their target rotation positions, so that the designated punch tool of the designated multi-tool holder is selected.
