For the needs of the wood industry, it is necessary to produce 3 axis CNC machines. It is intended for the production of wood products and the processing of softer metals. From the requirements of the final customer, we constructed the entire machine. We need to start the machine and test the controller, postprocessor and the use of CAM software. At the end of testing all the functions, we checked the accuracy of the machine. We did this with the Ballbar test. With the gradual measurement and program compensation errors, we tried to maximize the accuracy of the machine. After the calibration was completed, the CNC was tested on the actual application and cut off the simple piece on which we performed the measurements. The measurements were compared between the CAD model and the actual product model.
