What is precision machining?

For prototype and end-use parts, precision is a very important aspect of metalworking. Accuracy means you get a part that looks and feels exactly as you designed it, with no errors that could affect mechanical function.

Thanks to the rise of CNC machines, metalworking is now more precise than ever. Machinists can use a computer to program the trajectory of a cutting tool to a micrometer, virtually eliminating inaccuracies caused by human error. As long as the CNC machine is set up correctly, it should cut metal parts with high precision.

But there are many factors that affect the accuracy of metal processing. Machine quality, material selection, and even room temperature can all play a role, and some customers may have very different precision requirements than others.

This article discusses the ins and outs of precision metalworking, explaining concepts such as precision, precision, and tolerance.
