How To Keep Your CNC Machining Project On Budget

In general, CNC machining costs correlate to:

• Machining time and part's geometry

The more complex a part’s geometry, the longer the process will take to machine it and that means higher costs.

• Start-up costs

Related to computer-aided design (CAD) file preparation and process planning, start-up costs are significant for smaller volumes. Fortunately, they are also fixed. If the design and the surface finish are suitable for cost scaling, you can lower the unit price by applying economies of scale principles.

• Material cost

Material costs also affect overall costs. The goal is to select the material with the lowest cost that meets all design requirements.

• Surface finishing cost

Surface finishing is necessary for various products, which raises the price of the final product. A good finish, such as polishing, may be required to improve the aesthetics of the finished product and erase any scratches generated during the machining process.

At Etone Technology, we consider all the above factors while determining the cost of a CNC machined part. Our team works to reduce the cost by, for example, alternate material selection and modifications to the design. Design is the crucial factor from the manufacturer’s end as a simple and efficient design helps to reduce the per-unit cost of the CNC machined part.
