Abstract

A machining simulation apparatus includes a memory and a processor. The memory is configured to store a plurality of constituent models, a plurality of holding unit models, a workpiece model, and a machining program. The processor is configured to set a specific tool model, select a specific holding unit model among the plurality of holding unit models, calculate a recommendation value of a protrusion length of the specific tool model with respect to the specific holding unit model, create an assembly model in which the specific tool model and the specific holding unit model are combined such that the protrusion length is either the recommendation value or a corrected value that is calculated by correcting the recommendation value, and virtually execute the machining program in order to determine whether the assembly model abnormally interferes with the workpiece model or any of the plurality of constituent models.
