Making Accurate Parts on a CNC Lathe: Dealing with Thermal Growth!

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! 00:00 Intro 00:30 The Importance of Thermal Stability for Accuracy & Repeatability 01:40 KERN & High End Machine Builds to Control Thermal Growth 02:13 Controlling Machine Shop Environment & Other Considerations 03:32 CNC Machine Warm Up Routines 04:39 Parts Application, Fusion 360 NC Program, SMW Diamond Pins 05:15 Tool Probing, Updating Wear Offset, Coolant Temperature 07:19 Spindle Liners, & Sandvik Finishing Insert 08:44 Incorporating Code Into Machining Process to Control Temperature 09:54 Outro ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Links for this video Code Snippet on NYCCNC: https://bit.ly/2S5rnNZ Nicholas Hacko Watchmaker: http://bit.ly/2zU3Cgk KERN Tour: https://bit.ly/3ev6OBW ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Reach us / CNC Info: Speeds & Feeds: https://provencut.com Download Fusion 360: https://www.dpbolvw.net/click-9255839...
