Algorithm (Workflow)
This function, SGDIN912, generates a solid geometry model of a screw according to the DIN 912 standard. The function takes two input parameters, M and L, which represent the diameter and length of the screw, respectively.
Input Parameters
- M: Diameter metric, default is 2.5 mm if not provided.
- L: Length metric in mm, default is 3 times the diameter
M if not provided.
Output
- SG: Solid Geometry including frames.
Algorithm Steps
- Retrieve the diameter
M and length L from the input arguments, using default values if not specified.
- Load the DIN 912 standard data using the
DIN912 function.
- Adjust the radius for the hexagon using the
dofn function.
- Find the relevant table line
TL for the given diameter M using the DINfindinTab function.
- Set an overlap
ol of 0.1 mm.
- Create the initial screw geometry using the
SGDIN13 function with the adjusted length L + ol.
- Translate the geometry along the z-axis by
-L using the SGtransP function.
- Create additional geometry components
SGA and SGB using the SGofCPLz function with circular profiles.
- Combine the geometries using
SGunion and SGsubtract functions to form the final screw model.
- Set transformation properties for the geometry using the
SGTset function.
- Assign a stamp name to the geometry based on the diameter
M.
- If no output is requested, plot the geometry using
SGfigure, SGplotalpha, and SGTframeplot functions.
