Even though there are many number of post processors available, default post processors of Computer-Aided Design and Computer-Aided Manufacturing (CAD/CAM) software are not compatible with controllers of different manufacturers, and Numerical Control (NC) Codes generated by these software can’t be run on various Computer Numerical Control (CNC) machine controllers. Thus, interfacing CAD/CAM software to CNC machine is an involved problem in many industries. Also, postprocessors for certain controllers are not available. However, CLSF file (Cutter Location Source File) is same for all controllers. Once the CLSF file is prepared, these codes are then converted to opcode with the help of ‘C’ program and are send to micro controller which drives the motor as per the tool path requirement. Thus, in this study CAD/CAM software is interfaced directly to conventional machine by eliminating G and M codes. This interfacing has been experimented at smaller level for running Stepper motors with 8051 microcontroller. A small prototype machine was fabricated to demonstrate 2D cutting
