5 Design Tips To Cut The Cost When Manufacturing Your Parts

The smallest design decisions can greatly impact the cost of CNC machined parts. Do you know how a few adjustments to your part design can reduce costs? Take a look at these five design tips covering processing holes, manufacturing surfaces, and part depth.

1.  Adding a processing hole

Adding a processing hole helps to uniformize wall thickness and prevent deformation during heat treatment. 

2.  The structure of the part

In the original design, the thin wall thickness is easily deformed by clamping or cutting forces. In the optimal design, adding bosses increases the part's rigidity. 

3.  The outside surface

In the original design, processing an interior annular groove is challenging. In the optimal design, the groove is moved to the exterior surface of the part, making it easier to manufacture without affecting functionality.

4.  The machining area of milling

The machining area for milling should not be too deep, with a depth-to-width ratio not exceeding 3:1. Otherwise, the milling cutter is prone to breaking.

5.  Long milling cutter

If a long milling cutter is unavoidable, the design can be optimized to extend the cutter's life, as shown in the following pictures.
