» What is Tool Deflection in CNC Machining

Notice how there is always a hole that is smaller at the bottom than the top once you have milled a hole into it, using high-speed machinery? The reason for this is that the tool deflects. Tool deflection occurs once the tool is forced to bend. Unfortunately, there is no way to reduce the bending, it can only be controlled and reduced.

Tool deflection in feed and cross-feed directions affects the feed per tooth and the radial immersion in the machining process, respectively, which cannot be neglected in precision micro-milling. These factors were taken into account for the cutting force calculation and were used to update the cutting parameters so that an accurate surface topography generation can be predicted.

How To Reduce Tool Deflection In CNC Machining

Tool deflection is one of the common challenges in CNC machining. It will cause machine chatter, destroy the surface finish of processed parts, and destroy dimensional accuracy. Generally, the tool is firmly placed in the chuck, but during operation, the reaction force of the material often exceeds the operating force of the tool, which may push or deflect the tool in an unexpected direction.
