A NC geometric cutting simulator is widely used software that is able to verify a tool pathwithout real machining process by executing the machined shape check and the interferencecheck between a tool and a work piece during machining. However, current NC machiningsimulator is only considered for the geometric information of an objective shape and a tool. Forthis reason, it is difficult to represent cutting load, tool deflection and wear caused by a physicalphenomenon in machining process. The purpose of this research is to develop high accuracy NCgeometric cutting simulator named "advanced NC geometric cutting simulator" that is able toestimate the machining errors and represent them to the simulated shape. This paper describeseasy calculation algorithm about cutting force based on removal volume. Moreover the result ofmachining test about cutting force and its estimation is indicated.
