| Abstract: | In this paper, in order to deal with the calculations of spatial angles of slant holes, inclined planes, and obligue slots on the machine elements, the mathematical expressions are presented according to the theory of projection. The calculation of spatial angles are converted into that plane angles, the drawing processes are simple and convenient, and the results of the calculations are accurate. This paper can be taken as a basis for the jig design and the computer programming. |
