How to Reduce CNC Machining Costs

When it comes to CNC machining, planning is critical. Often, CNC machining designs and projects can become unnecessarily complex - and as with almost everything in life, time is money. At Liangyin, we understand that some designs require precise details that can't be simplified, but if you want to reduce costs and have the design flexibility to change design features, this blog post is for you.

By understanding the CNC machining process and the factors that affect price, you can reduce the cost of your machining project while maintaining or improving functionality. Manufacturability is the level of complexity of the manufacturing process required to make a given part. In essence, the higher the manufacturability, the lower the cost.

This blog post will review some of the key ways you can reduce the cost of CNC machined parts and enclosures.

Material Costs

In machining, the harder the material, the more difficult it is to machine. This is because we must use less time efficient processes and cutting parameters.

We recommend using 6061 aluminum for CNC jobs where you are tolerant of the material. This type of aluminum is typically used for CNC machining. 6061 aluminum is ideal for CNC projects because it offers a balance of toughness, strength, corrosion resistance, and most importantly, excellent manufacturability.

 

Design

The more you can simplify your design, the lower your project costs will be. The details, dimensions and geometry of your project can have a significant impact on cost. Complex, highly detailed parts may require multiple setups, resulting in higher costs. Some complex projects with multiple faces may be cheaper with appropriate modifications.

The following are some design tips to help you reduce costs.

◭ If your part has holes or slots on all faces, consider moving these details to the same face whenever possible. This will reduce setup costs and save you some money.

◭ Small features such as holes and slots can lead to complex and expensive designs.
