Returns two bodies with DIN912/DIN985 locking method
Use carefully: The 'SGlockingDIN912DIN985' function has not yet been extensively tested
Description
This function takes two solids {SGA, SGB} and designs a screw connection between the two bodies using a DIN912 cylinder head screw and a DIN985 self-locking nut. The screw head is always in SGA and the nut in SGB. The screw is specified as an array with {diameter and length according to DIN 912}. To position the screw connection in the solids SGA and SGB, either two frames {'FA', 'FB'} or a relation such as 'ontop', 'behind' are required. The frames are used to arrange the screw and the nut. If the string parameter "align" is used, the position of the body SGB is also adjusted. Without this parameter, the bodies remain in their positions, which makes sense in most cases of a design process. The string parameter "supp" is used to check whether there is enough material in SGA and SGB to accommodate the screw with the defined size. If necessary, supplementary material is added to the solids SGA and SGB so that the screw connection is technically possible.[spchk]

Syntax
SGs=SGlockingDIN912DIN985([M,SGs,FNs,"supp","align"])
Input Parameter
M: | | [M Diameter Length and distance] of DIN 981 Screw |
SGs: | | cell with Solids {SGA, SGB} |
FNs: | | cell with Frame Names {'F','B'} or simple relation such as behind |
"supp": | | if used, material is supplemented to hold the screw, nut and head |
"align": | | if used, the position of SGB is aligned with A, otherwise remains unchanged. |
Output Parameter
SGs: | | cell list {SGA,SGB} mit new frames 'C' if spatial relations were used |
Examples
A=SGbar([10 5 10]); A=SGTset(A,'F',TofFS(A,[0 1 0]));
B=SGbar([20 5 10]); B=SGTset(B,'B',TofFS(B,[0 -1 0]));
SGlockingDIN912DIN985([2.5 8],{A,B},{'F','B'}) % Using frame names
SGlockingDIN912DIN985('',{A, B}, 'ontop') % using ONE spatial relation
SGlockingDIN912DIN985('',{A, SGsphere(4)}, 'ontop')
SGlockingDIN912DIN985([3 20],{A, B}, 'behind') % Long screws without required material
SGlockingDIN912DIN985([3 20],{A, B}, 'behind','supp') % Long screws with supplemented material
