CNC Machining Effects on Stress and Dimensional Stability

Leave a Comment / CNC machining parameters, CNC Machining Processes /

Understanding how CNC machining processes affect internal stress and dimensional stability is essential for producing reliable and accurate parts. Each stage of machining — from rough cutting to finishing — can influence not only the tensile stress within the material but also cause stress release that results in part deformation and unstable dimensions. This section […]

When Should Threaded Holes Be Milled Instead of Tapped?

Leave a Comment / CNC machining parameters, CNC Machining Processes /

In CNC machining, both tapping and thread milling are common methods to create internal threads. However, under certain high-precision conditions, tapping may no longer be suitable. One key situation is when a threaded hole must meet both tight diameter tolerance (below ±0.005 mm) and geometric tolerances such as true position or coaxiality.  Why Is Tapping

Dimensional Changes from Stress Release in CNC Machining

Leave a Comment / CNC machining parameters, CNC Machining Processes, CNC milling machines, CNC Precision Machines /

In CNC machining, we often encounter dimensional changes caused by stress release in materials. When a material undergoes milling, drilling, or cutting, internal stress redistributes, potentially leading to shrinkage or expansion of the workpiece, resulting in dimensional instability. This not only affects machining precision but also impacts assembly compatibility. To ensure product quality, we implement
