Cutting contour accuracy
Cut contour accuracy is the agreement of the actual cut line with CAD specifications. It depends on machine kinematics and process parameters.
Physical-Chemical Mechanism of Action
The cut contour accuracy is determined by the precise control of the tool movements during cutting. This includes the precision of the machine axes, the speed, and the pressure during cutting.
Metallurgical Relevance & Welding Risks
Poor cut contour accuracy can lead to incomplete or missing cuts. This can result in workpieces with inaccurate shapes and possibly malfunctions of the components. Moreover, an inaccurate contour can lead to increased material waste and longer processing times.
Workshop Practice & Action Instructions
To ensure cut contour accuracy, machines must be calibrated regularly. The cutting speed should be set such that the material is not overstressed. The pressure during cutting must be continuously monitored and adjusted as needed. It is also important that the CAD specifications are correct and that the operator operates the machine properly.
