| Summary: | Most manufacturing industries use Computer Aided Design (CAD) and Computer
Aided Manufacturing (CAM) transforms manufacturing system by improving
productivity of production. The main purpose of Computer Numeric Control (CNC)
Simulator is to create a faster production process and components and tooling with
more precise amount of raw material thus minimizing waste, while simultaneously
reduce energy consumption. This paper describes effective approaches of CNC
simulators for CNC milling machine. Before real machining, several simulations are
generated to identify excellent machining method. CAD/CAM software is most often
used for machining of prototypes and finished parts. Machining parameters can affect
the surface quality of product in CNC machining. The combination of synchronized
movements on three axes restrict user machining a part with complex shape. The
purpose of this research is to identify machining parameters for CNC Simulator and
real machining. To compare machining simulations approached by using different
CNC Simulators. Another purpose is to identify the accuracy of simulation and actual
machining. CNC Keller, Mastercam X2 and CATIA V5 are used to identify the
effective method to machining complex geometric shape in CNC machine; CNC 3-
axis machine and CNC 5-axis machine. With different combinations of orientations
sets, the total machining times were considered as the crucial of roughing and
finishing. In the simulations studies, comparisons are made between those three CNC
Simulators and real machining.
