Algorithm (Workflow)
This function, SGmotorshaft, generates a solid geometry for a motor shaft with an undercut. It is part of the SG-Library and was created by Tim Lueth.
Input Parameters
- D: Diameter of the shaft. Default value is 0.25.
- L: Length of the shaft. Default value is equal to D.
- r: Undercut radius. Default value is 0.25.
- ol: Step offset. Default value is equal to r.
Output Results
- SG: Solid Geometry including frames.
- PL: Point List.
Algorithm Steps
- Retrieve input parameters using
getfuncparams function. If not provided, use default values:
D is set to 2.5 if not specified.L is set to D if not specified.r is set to 0.25 if not specified.ol is set to r if not specified.
- Calculate the radius
R as half of D.
- If
ol is a scalar, convert it to a two-element vector [0, ol].
- Assign
ox to the second element of ol and ol to the first element.
- Define the point list
PL for the motor shaft geometry.
- Mirror the point list
PL to create PLU and append it to PL.
- Apply radial edges to
PL using PLradialEdges function.
- Remove successive identical points from
PL using VLremsuccident function.
- Generate the solid geometry
SG by rotating the point list PL using SGofCPLrot.
- Set the transformation of
SG using SGTset with a rotation matrix.
- If no output is requested, plot the geometry using
SGfigure, SGplotalpha, and SGTframeplot.
