Paragraph 29 DEFINITIONS OF TERMS IN THIS ANNEX

Changes not yet applied. Later legislation changes this provision in ways not yet written into the text below:

“Contouring control” (2) means two or more “numerically controlled” motions operating in accordance with instructions that specify the next required position and the required feed rates to that position. These feed rates are varied in relation to each other so that a desired contour is generated (ref. ISO/DIS 2806—1980).
