Does anyone know how to calculate ideal tip speed, cutter angle,blade thickness and torque required for a rotary grass cutting blade driven by a battery powered electric motor.

RE: Agricultural Machines
Start off by benchmarking existing or similar units in the market. What are they using for tip speed, blade thickness and cutter angle. Check with OPEI (Outdoor Power Equipment Institute) regarding standards and best practises. ANSI/OPEI B71.4 Safety Specifications for Commercial Turf Care Equipment specifies a maximum tip speed of 19,000 ft/min.
Is your electric motor your limiter? Then work from there as to your maximum torque available and tip speed, etc.

You might also benchmark disc swathers--they seem to have a lot of research behind them, and everyone in the industry seems to have landed in about the same place.
