Abstract:
1. A clamp instruction method for an addition axis comprising the steps of, at a stage of working a work piece with a tool: measuring a rotational torque generated by the working with respect to the addition axis coupled to a table which supports one of: generating a clamp instruction to the addition axis when the rotational torque exceeds a predetermined reference value, wherein prior to working with the tool, further comprising the steps of: determining whether the tool is a load tool whose working generates a rotational torque on the addition axis found beforehand to exceed a set reference value, and when the tool is the load tool, generating the clamp instruction before working with the load tool, and wherein at a time of instructing a tool change, further comprising the steps of: determining whether or not a load tool is to be disposed on a spindle axis through a tool change operation, and when the tool is the load tool, generating the clamp instruction during the tool change operation.
