Algorithm (Workflow)

This function, SGbitISO1173, is designed to create a solid geometry model of a bit according to the DIN 3126 ISO 1173 standard. The function takes several input parameters and returns a solid geometry object.

Input Parameters

• s1: Not explicitly used in the code.
• s2: Not explicitly used in the code.
• l: Length of the bit. Default value is 15 mm.
• d1: Not explicitly used in the code.
• d2: Not explicitly used in the code.

Algorithm Steps

1. The function begins by retrieving the input parameters using the getfuncparams function. It sets default values if parameters are not provided:
   • d is set to 6.3 mm, which is equivalent to 1/4 inch.
   • l is set to 15 mm.
   • n is set to 6.
2. The radius r1 is calculated using the formula r1 = dofn(n) * d / 2. The function dofn is assumed to determine a factor based on n.
3. A solid geometry SG is created using the function SGofCPLzchamfer with the following parameters:
   • PLcircle(r1, n): Creates a circular profile with radius r1 and n segments.
   • l: The length of the bit.
   • 1: Chamfer parameter.
   • false: A boolean parameter, possibly for chamfer direction or type.
4. The function SGTset is used to set transformation properties of the solid geometry:
   • 'B' with vector [0 0 -1]: Sets a base transformation.
   • 'F' with vector [0 0 +1]: Sets a forward transformation.
5. If no output is requested (nargout == 0), the function visualizes the solid geometry:
   • SGfigure: Initializes a figure for plotting.
   • view(-30, 30): Sets the view angle for the plot.
   • SGplotalpha(SG, 'g', 0.9): Plots the solid geometry with green color and 90% transparency.
   • SGTframeplot(SG): Plots the transformation frame of the solid geometry.
