Cutting gap tolerance
Tolerance for the width of cut gaps and contour accuracy relative to CAD specifications, influenced by machine precision and thermal distortion. It ensures accurate dimensional accuracy in assembly production.
Physical-Chemical Mechanism of Action
The kerf tolerance refers to the permissible deviations in cut gap widths and contour shapes compared to the CAD specifications. These tolerances take into account the accuracy of the machines used as well as thermal distortions that can occur during the manufacturing process.
Metallurgical Relevance & Risks in Welding
A tolerance that is too small can lead to narrow cut gaps, which can make welding more difficult and impair the strength of the joint. A tolerance that is too large, on the other hand, can lead to inaccurate contours and possibly to malfunctions of the assembly.
Workshop Practice & Action Guidelines
To ensure an optimal tolerance, the machines should be calibrated regularly. Thermal distortion can be minimized by controlled cooling and the selection of suitable materials. It is important to follow the CAD specifications exactly and to check the actual dimensions regularly.
