HAAS Acceleration Calculations

VF3

  • Y AXIS: Mits 900W Servo, 1500 Rated RPM, 3000 Max RPM, 5.39NM
  • Ballscrew: 40MM DIA 8MM Pitch
  • Max load: 3500 lb (1588 kg)
  • Max thrust: 2550 lbf (11343 N)
  • Advertised max feedrate: 1000 ipm
  • Calculated max feedrate (max rpm * pitch): 944 ipm
  • Max cceleration with rated load (+ 800lb saddle/table): 11343 / (1588 + 362) = 5.81 m/s2 (0.59 G)
