Max Feed Rate Optimization

Theoretical Background & Mathematical Equations

Traditional CAM programming uses a constant feed rate. However, when a tool enters a corner or a slot, the wrap angle increases dramatically. This causes a spike in cutting forces, tool deflection, and temperature. hyperMILL's optimization engine adjusts the feed rate dynamically based on several mathematical models.

Volumetric Material Removal Rate (MRR)

The Material Removal Rate (MRR) represents the volume of material removed per unit of time. It is defined as:

Physics of High-Performance Cutting (HPC) & Machine Dynamics

Optimizing feed rates requires balancing several physical phenomena:

Specific Cutting Force ($k_c$) and Mechanical Torque

The cutting force ($F_c$) required to shear metal is expressed by the Kienzle equation:
