5 Common Rapid CNC Machining Questions

TIPS WITH TONY

Most are familiar with machining, but what makes it unique at Proto Labs? These are a few of the most common questions we receive about our rapid CNC machining service. These answers will help you optimize your design for CNC machining and determine how it can improve your product development efforts.

CNC machining is a subtractive manufacturing process that mills away at a block of solid plastic or metal.

1. What is unique about Proto Labs’ CNC machining process?
In order to efficiently machine low quantities as fast as possible, we do things a bit differently compared to a traditional machine shop. When you upload a 3D CAD file to protolabs.com, our proprietary software analyses the design, creates a quote, and generates the CNC toolpaths. By automating the front-end of the manufacturing process, we can machine a part in as fast as one day.

2. How does the quoting process work?
Once you upload your 3D CAD model to our website, the software calculates the price—not a budgetary estimate—to machine your design. Within a few hours, you’ll receive an email with an interactive quote. Here, you can select different materials and quantities and receive real-time price updates. The quote even contains a 3D-view of your machined part, which will highlight any differences between the machined part and the original 3D CAD model. See a ProtoQuote preview here. Continue reading
