Machining simulation system

A machining simulation system comprising:

• a numerical control apparatus capable of performing a machining simulation with a tool shape model and a material shape model;
• and
• a machining simulation apparatus capable of performing a machining simulation with the tool shape model and the material shape model and communicating with the numerical control apparatus via a communication unit or a storage medium so as to mutually transmit and receive data,
• wherein the machining simulation apparatus comprises:
• a shape model output unit configured to output a tool shape model and a material shape model that can be used in the numerical control apparatus, and
• a setup position output unit configured to output a tool setup position and a material setup position on a machine tool,
• wherein the numerical control apparatus comprises:
• a shape model reading unit configured to read the shape model output from the shape model output unit, and
• a setup position reading unit configured to read the setup position output from the setup position output unit.
