Method of controlling lineup of tools in numerical control machine tool

摘要

The machining to be achieved is classified in accordance with the machining shape into a plurality of machining units. A tool combination memory stores tool combination lines each containing an array of tool information in the sequence of use in each machining unit. As the operator appoints some of the machining units, corresponding tool combination lines are read out from the tool combination memory and are stored in sequence in a machining program memory. The tools presented by the tool combination lines in the machining program memory are then rearranged and lined up on the basis of the tool to form a machining tool combination. The machining is made in accordance with the machining tool combination in such a manner that the machinings of different machining units achievable by a tool common to these machining units are conducted simultaneously without necessitating repeated mounting and demounting of such tool.
