Spindle Shaft Design, 7th April

  • Developed a model to predict the peak cutting force and shaft torque
  • Wrote a matlab tool to determine peak forces and bending moments in spindle

shaft and bearings

  • Wrote a matlab tool to specify bearing from cutting force, torque, and desired life

and reliability (via the Weibull Equation)

  • Specified a collet from sheets provided in lab
  • Used results from above tools and supplied lathe solid model to specify shaft

dimensions.

    • 30 mm shaft outer diameter, 50mm diameter for centre section
