Case study of cost reduction in metal processing due to changes in the C chamfering specification of peripheral R.

Case study of cost reduction in metal processing due to changes in the C chamfering specification of peripheral R.

Programming made easy! It leads to cost reduction through labor savings!

In the design instructions for square mechanical parts such as plate blocks, it is often seen that the outer corners are indicated with a radius, such as 5R. In the machining of such mechanical parts, programming the R shape takes time, and it also becomes difficult to align dimensions and joints, which increases the man-hours required to stabilize quality, leading to higher costs. In the drawings of parts like plate blocks, if there are no mechanical issues, changing the outer corners to a chamfer indication such as C5 can help reduce costs. This not only simplifies programming but also allows for chamfering with a grinder, contributing to cost reduction through decreased man-hours. 【Example】 ■Content: Cost reduction in metal processing by changing the outer R to a C chamfer indication ■Issue: Increased man-hours to stabilize quality leading to higher costs ■Proposal: Change the outer corners to a chamfer indication such as C5 ■Applications: Cost reduction, cutting processing, machining, lathe work, precision processing *For more details, please refer to the PDF document or feel free to contact us.
