This paper inculcates a novel method to control the 3-axis machine with Computer Numerical Control (CNC) codes using LabVIEW and Programmable Logic Controllers (PLC). LabVIEW is used for virtual user interface and PLC is used for machine control. Without burdening the CNC programmer, the paper provides an alternate way to control the CNC machine with minimum cost in comparing with the conventional method. The programmer can use any of the CAD/CAM software to generate the CNC codes. The generated CNC codes are browsed to LabVIEW by means of virtual user interface. The inbuilt program in the LabVIEW can sense any of the CNC codes. After sensing, the codes are being processed in the software to find the co-ordinates of the tool path. The extracted tool path co-ordinates are sent to PLC programming software, RS Logix 500 through OPC server. The inbuilt program in the RS Logix 500 can get the co-ordinates and move the tool accordingly. The overall method is programmed for incremental mode of CNC, so that there is no need of getting positional feedback from the machine. Hence, without having knowledge in the field of LabVIEW programming and PLC logics, the CNC operator can treat the machine similar to the conventional machine.
