Algorithm (Workflow)

This function calculates the module of a gear given the number of teeth and the diameter. It is part of the SolidGeometry library.

Input Parameters

Output Results

Algorithm Explanation

  1. Calculate the effective module me using the formula: me = d / (z + 2).
  2. Round the effective module me to the nearest 0.1 using the function rounddiv(me, 0.1) to get the final module m.
  3. If no output is requested (nargout == 0), perform the following actions:
    • Call SGfigure to possibly create a new figure for visualization.
    • Call PLgearDIN(m, z) to plot or process the gear with the calculated module and number of teeth.
    • Call sprintftext(me) to display or log the effective module.

Example

To calculate the module for a gear with 17 teeth and a diameter of 9 mm, use the function call: mofzd(17, 9).
