The final project item was produced according to the drawing shown in the attachment. In order to obtain the necessary dimensions and measurements required for the fabrication of the item, a 3D model of the workpiece was created. Based on the model, technological documentation was prepared. The CNC code was generated using the WinNC program and is valid for the Sinumerik 840D MILL control unit. Prior to the actual fabrication of the item on the machine, dimensional control of the raw material and a simulation of the machining process are performed. Since the machining is done on both sides, dimensional control is carried out before and after clamping the workpiece in the vice. The control is conducted to achieve the desired accuracy of the workpiece dimensions and ensure the safety of the milling process. Through the simulation of the machining process, possible errors that may occur during program execution are detected and rectified. After the workpiece fabrication process, final dimensional and visual inspections are performed.
