MC cutting process → Cost reduction through sheet metal unit + bending process + rib addition.

This is a case study of a cost reduction method for a rigid MC cutting processing unit, which is improved in shape by VA and VE, using a sheet metal processing unit with a bending structure and additional ribs.

This is a method to reduce costs by introducing units made of MC plate material. The theme involves significantly reducing processing man-hours while considering rigidity through cutting processes, starting from shape construction through machining. ■ This method is not suitable if precision in plate thickness is required through MC cutting. ■ Original part information: 2 pieces of SS material, reference dimensions: 10T×100×200, 2 units 6F processing + milling processing, holes, and screw processing ■ VA, VE content: Improvement of 2 pieces of plate material into sheet metal shapes. The reduction in thickness is addressed by incorporating bending processes to construct rigidity. If rigidity is insufficient, adding ribs can be effective. ■ Shape construction through cutting processes literally involves shaping by removing material, and the more material that is removed, the more processing man-hours are required. However, sheet metal processing constructs shapes through cutting, resulting in overwhelmingly fewer processing man-hours and significant cost reductions. ■ The issue is that the dimensional tolerances achievable through cutting processes differ from those in sheet metal processing, so specifications must be considered accordingly.
