Milling cutter in cut with chip flutes

The chip chamber (or clamping area ) is a recess between the cutting edges of cutting tools for receiving the separated chips during the cutting procedure . If the cutting edge leaves the workpiece, the chamber behind it is exposed; the chips can fall out or be blown out or rinsed out by the cooling lubricant .

The size of the chip chambers depends on the volume of the chips , which is dependent on the cutting width and cutting depth . If the chip chambers are too small, there is a risk of breaking the cutting edge or the entire tool, as chips that move up increase the pressure on the tool and, above all, on the machined surface, which creates increased friction. As the chip formation progresses , the required torque increases with rotating tools (drills, milling cutters ...) , otherwise the force until the tool no longer cuts or breaks. Cutting edge geometry and cutting material resilience place tight limits on the chip chamber design, so that it cannot always be optimally adapted to the chip volume.

In a saw, for example, the recesses between the teeth, the tooth gaps, form the chip chambers.
