Graph method of main thread cutting sees cutting of 1 columnar whorl the graph is shown 1 times. In type of G32 X(U)~ Z(W)~ F~ of process designing format: The terminal coordinate of cutting of whorl of X(U) , Z(W) - is worth; Columnar whorl cutting is when X omits, cutting of end panel whorl is when Z omits; Awl whorl cutting is when X, Z all does not omit; (X coordinate is worth a basis " mechanical design manual " check a watch to decide) lead of F - whorl. Whorl cutting should notice to install litre of enough fast feed in two end paragraph δ 1 and fall fast retreat a knife paragraph δ 2. Exemple: Try write the machine program that the graph shows thread 1 times. (whorl lead 4mm, rise fast feed paragraph δ 1=3mm, fall fast retreat a knife paragraph δ 2=1.
