Taper of 3 (turning) when turning did not retreat the whorl of knife chamfer, appropriate uses statement of loop of G92 whorl cutting, this instruction is had return knife function automatically, so won't cut whorl surface. Vitta threading machine is shown 2 times like the graph, here introduces this directive simply: Statement form: G92 X(U) _Z(W) _R _ F _ among them: P1 is initial drop, x(U) _Z(W)_ is the coordinate of whorl terminus P3. P3P4 is the distance that retreat a knife. R is cutting terminus P3 is measured to the X axial of start P2 (the half amount that has a sign, if the X coordinate of cone start P2 is more than the X of terminal P3,be when coordinate be worth) . R is the parameter that controls taper. It is like taper 1: 16, criterion the absolute value of R is: L/(16 × 2) , as above exemple, point of a knife is 10mm to end panel, the P3P4 that retreat a knife measures for 1mm(unilateral) criterion: Awl whorl length: 52.

34) presses taper requirement process designing: What measuring instrument of vitta whorl individual event measures is 25.
The change of the diameter on 4mm length is measured, if make the same score type vitta whorl every 25.
4mm10 tooth, measure the metabolic volume of the diameter on 10 pitch. Taper is a ratio, the circumstance with consistent unit leaves pass the time in a leisurely way of two balance each other, the number that turns a boundless into key link. Be like taper 1: The standard reading of 16 should be: 1/16=0.
0625, number showing disrespect or contempt should be taper dial gauge 62.
5. Some produce the treatment quality with better to assure manufacturer, to the control of taper limits made strict provision, its are optimal the value is not certainly 62.
5, must meet when process designing be worth process designing according to first-rate taper. Be like set optimal taper to be worth for 0.

84 when asking without special taper, can press process designing of the first kind of method. When having a demand to taper, should press process designing of the 2nd kind of method. When undertaking adjustment to taper, can consult to ask to make up decided program to undertake adjustment by taper. CNC Milling CNC Machining
