Relationship between motor amps and force through the cutting blade 2

[Vipul19]

I have a cutting operation where I had a 14" blade with 80 teeth, spinning a 1800 rpm with 10HP motor. The material being cut was pushed through at 8.3ft/min. We measured the amp load on the motor.
The force required to push the material through was approx 800lbs.

Then we changed the blade to 36 teeth and pushed the material through at 20 ft/min and measured the amp load it was approx 50% of before. I can't measure the force anymore, but would like to know if there is a way to calculate?

No. The units of MRR are volume/time, for which you have to measure and include the cut width, the cut depth, and the axial feedrate.
