Thermal growth affects part accuracy and repeatability way more than we realized. If you have tooling, workholding, and toolpaths dialed in but still have trouble with accuracy and repeatability, it may be related to thermal growth. Let’s talk about the importance of thermal stability, how slight, sudden changes in machine shop environment can blow tolerances, and how to use NC programs and variables to keep the lathe at the right temperature before parts are made!
