Case study of cost reduction in metal processing through the relaxation of flatness tolerances.

By relaxing flatness tolerances, we reduce machining man-hours and achieve cost reduction!

In the drawing, there are indications for parallelism and flatness with respect to reference surface A. Additionally, the presence of mounting holes suggests that it can be used by tightening with bolts. For such mechanical parts, achieving flatness becomes increasingly difficult as the workpiece size increases. The increase in processes such as rough machining, semi-finishing, and finishing requires more time and contributes to the cost increase of mechanical parts. If there are no design issues, it is possible to relax the precision indication for flatness and only relax the tolerance for parallelism with respect to reference surface A, thereby eliminating the semi-finishing process and completing it with finishing machining. This can reduce the man-hours for cutting processes and achieve cost reduction.
