Geometric Conditions That Constitute the Contour of Brass Precision Turned Components Products
When the program is edited manually in the turning process, the coordinates of each node need to be calculated; when the program is edited by itself, all the geometric elements of the contour need to be edited. Therefore, when analyzing graphs, we must pay attention to the following aspects:
A. whether some dimensions are missed on the observation drawing, which makes its geometric conditions insufficient and interferes with the composition of the contour;
B. observe whether the drawing line part on the diagram is fuzzy or the dimension mark is not clear, so that the editing program can not be started;
C. check whether the geometric conditions given in the drawing are improper, which leads to the mathematical problems;
D. the dimensioning method on the drawing shall be suitable for the characteristics of CNC lathe processing, and the same datum dimensioning or direct coordinate dimensioning shall be used.
