Design Guidelines
There are a few easy steps you can take to optimize your designs for computer numerical control (CNC) machining. By following design-for-manufacturing (DFM) rules, you can get more out of CNC machining's broad capabilities. This can be challenging though, as industry-wide specific standards do not exist. If you are optimizing for costs, check out this guide to designing cost-effective parts for CNC.
Tolerances
We guarantee that our manufacturing partners follow ISO 2768 standards for all CNC machined parts. Parts machined with metal will follow ISO 2768-m (medium) or ISO 2768-f (fine). Parts machined with plastics will follow 2768-m (medium). Geometric tolerances down to ± 0004 in. (0.010 mm) are possible but must be clearly indicated in technical drawings. We can achieve tighter tolerances on shafts with up to H7 fits with manual quoting and on occasion tighter.
CNC FAQs (Frequently Asked Questions)
What is CNC?
Computer numerical control (CNC) is the automation of machine tools by means of computers executing pre-programmed sequences of machine control commands. This is in contrast to machines that are manually controlled by hand wheels or levers, or mechanically automated by cams alone. In modern CNC systems, the design of a mechanical part and its manufacturing program is highly automated. The part’s mechanical dimensions are defined using computer-aided design (CAD) software and then translated into manufacturing directives by computer-aided manufacturing (CAM) software. The resulting directives are transformed (by “post processor” software) into the specific commands necessary for a particular machine to produce the component and then are loaded into the CNC machine.
What is CNC Machining?
CNC machining is a manufacturing process in which pre-programmed computer software dictates the movement of factory tools and machinery. The process can be used to control a range of complex machinery, from grinders and lathes to mills and routers. With CNC machining, three-dimensional cutting tasks can be accomplished in a single set of prompts. When a CNC system is activated, the desired cuts are programmed into the software and dictated to corresponding tools and machinery, which carry out the dimensional tasks as specified, much like a robot.
