fixedtool

Fixedtool refers to a cutting tool that remains stationary during a cutting operation. In various machining contexts, it stands in contrast to tools that rotate, oscillate, or otherwise move as part of the cutting action. Fixed tools are typically mounted in a rigid toolholder or fixture and cut through relative motion between the workpiece and tool.

In traditional metalworking and woodworking equipment such as planers, shapers, and certain specialized milling setups, the tool may be fixed in the cutter head while the workpiece is advanced past it, or the machine axis moves the tool along a fixed path. Operationally, the fixed-tool approach emphasizes rigidity and simple tool geometry, with cutting actions produced by feed or work motion rather than tool rotation.

Variants of fixed tools appear in forming operations, where a stationary blade or punch shapes the workpiece as it is moved against the tool, and in some CNC configurations that use fixed knives or plows for profile finishing. The term is occasionally used in discussions of fixture design and toolholding to describe components kept in a constant orientation to minimize setup changes.

Advantages of fixed tools include high stiffness, predictable edge geometry, and simple maintenance. Limitations include limited ability to produce complex contours, potential for longer cycle times, and reliance on precise workpiece motion to generate the desired profile.
