More than that, we will explore how to effectively control thermal expansion and contraction through various techniques and strategies. Let’s embark on this journey to unlock the secrets of precision machining!
Understanding Thermal Deformation
What is Thermal Deformation?
Thermal deformation refers to the changes in shape or size of a material due to temperature variations. When machining stainless steel, the cutting process generates heat, causing the material and the tool to expand. Once the machining process is complete and temperatures normalize, the material may contract and warp, resulting in dimensional inaccuracies.
Causes of Thermal Deformation
Several factors contribute to thermal deformation in CNC machining:
