Although toolpaths with constant angular engagements result in smoother machining operations, this approach has some limitations when it comes to critical machining cases. One of the fundamental presumptions of this geometric approach is to directly relate the physical outputs (cutting force, chip load, spindle load) to the removed/machined geometry, however, the science behind machining says otherwise.

DELPro - DELMIA  Dynamic Tool Path optimization is a user-friendly machining process diagnosis and optimization plug-in for 3DExperience. DELPro considers the geometry of the chip being removed, workpiece material properties, tool geometry, and tool motion. This deep understanding of metal cutting physics is applied to the machining process to adjust feed rates and produce smoother machined surfaces at higher material removal rates. 

DELPro emulates the actual metal cutting process in DELMIA based on the underlying physics and detects process mishaps along the tool path whether the engagement is kept constant or varying. Critical problems such as
    • spindle overload – torque/power violations
    • excessive cutting forces… hence tool deflection/breakage, part distortion, fixture instability
    • unbalanced chip load… hence premature tool wear, tool chipping

are avoided by the automatic adjustment of feed rates calculated by the same physics-based engine and the original tool path geometry and strategy are left untouched.
