DFM Analysis For CNC Machining Aluminum Complex Cavity Part

In the manufacturing industry, Design for Manufacturing (DFM) plays an important role in optimizing production processes and minimizing costs. It serves as a pivotal bridge between design and production, ensuring a seamless transition from prototyping to mass production.

Taking a typical aluminum cavity part as an example, this article analyzes its DFM from a machining perspective and discusses how to optimize production efficiency and achieve quality control.

Project Overview

The product is a large cavity part with dimensions of 328×272×87.5mm. Made of AL6061 material, this component features fins on its A-surface for heat dissipation. There are two deep holes (orange hole surfaces) on the front and back as coolant circulation channels, forming a loop through small cavities on the B-surface(orange surface). The internal cavity is hollowed out mainly to provide assembly space for other components. And the threaded holes and pillars distributed on the external and within the cavity serve as fasteners for the assembly of other parts.
