It produces a maximum of 10% tool engagement with a maximum Z depth and higher feedrates between the transition moves.īoth toolpaths have an arc-in path followed by a straight line or a line that follows the contour shape followed by an arc-out path. The tool then removes the same amount of stock when finishing surfaces, which ensures more uniform surface quality.Ī peel-type toolpath is similar and generates many of the same benefits. Reduced tool deflection, which provides a closer-to-nominal stock allowance in all areas of the contour.This reduces load on the tool and drastically reduces having to recut chips. Chips are thinner and these types of techniques provide superior chip removal, especially when using flood coolant or air blast.It also keeps the tool sharper longer by uniformly wearing the cutting edges. Using the entire flute length decreases cutting forces, which contributes to process stability by reducing vibration and load on the spindle bearings. Uniform tool engagement both radially and axially.This improves process predictability and extends tool life. Lower temperature at the cutting zone, which puts less thermal load on the tool.
In the decade or so that trochoidal milling has been around, the industries we serve have seen positive impacts on tool longevity and 10% to 15% better metal removal rates (MRR) than conventional machining. Like the pen in a Spirograph, the trochoidal toolpath is circular rather linear. The user pinned to a piece of paper a plastic ring with gear teeth cut into the inner and outer diameters, then placed another smaller geared plastic ring on either side, inserted a ballpoint pen, and moved the smaller ring around the larger one. Think also of the 1960s-era Spirograph toy that produces colorful roulette curves. This is the principle on which trochoidal milling is based. Each revolution produces a trochoidal movement. If we applied enough force to bring it back to earth, the satellite would spiral downward. Imagine a satellite orbiting the earth at a constant height.
