We require a more modern way of thread making, utilizing a tool known as a thread mill to interpolate the thread profile. This creates a precise thread, as well as a single milling tool could be used to chop any thread size that shares that pitch, saving production and setup time. Because of this, UNC and UNF threads from #2 approximately 1/2 in., and metric threads from M2 to M12 are possible, all inside a single toolset Rapid Manufacturing.

Want to experience a part number, description, or logo milled with your parts? The toolsets at Protolabs can handle machining the majority of text required, provided the spacing between individual characters and also the stroke utilized to “write” them measures no less than 0.020 in. (0.5mm). Also, text needs to be recessed instead of raised, and it's suggested 20-point or larger fonts for example Arial, Verdana, or similar Sans-Serif fonts provide.

By standardizing the raw material, multiple product series can be done from precisely the same format material. Simply put: mill more off. Changing products happens faster for the reason that operator can make use of the same fixture. Resulting in less downtime.

With a zero point clamping system for the machining table, the operator can rapidly change fixtures. Moreover, the extra edge is that new fixtures is usually prepared even though the CNC machine is machining. With a zero point clamping system around the machining table you're also prepared for automated fixture changes.

Sticking to standard sizes is usually important when designing threads. The larger the thread, the better it is to machine. Length really should be kept to your maximum of 3 x the nominal diameter of an hole. Avoid extra costs by adhering to off-the-shelf thread sizes with your parts. Tip: A list of standard thread sizes based on Xometry can be obtained here.

To keep an eye on the recommended rules for CNC machining, here’s a simple reference checklist to provide you started. Of course, there's always exceptions for the rules as they’re below.
