Thread Cycle Method

The penetration of the threading tool can be completed using two separate modes: along the thread flank or perpendicularly along the main threading direction. The pass depth can be variable, so as to follow a constant or fixed chip section, and in this case, it is the chip section that varies.

1 flank constant volume

The depth of each pass is calculated such that the tool always removes the same volume of material. The tool is plunged along the flank of the thread, by taking into account the angle of the thread such that only the opposite edge is working.

1 flank constant depth

The depth of each pass is equal to the total depth of the thread divided by the number of passes to carry out. The tool is plunged along the flank of the thread, by taking into account the angle of the thread such that only the opposite edge is working.

2 flanks constant volume

The depth of each pass is calculated such that the tool always removes the same volume of material. The tool is plunged perpendicularly to the thread such that the two edges are working simultaneously.

2 flanks constant depth

The depth of each pass is equal to the total depth of the thread divided by the number of passes to carry out. The tool is plunged perpendicularly to the thread such that the two edges are working simultaneously.

Alternating flanks with constant volume

The depth of each pass is calculated such that the tool always removes the same volume of material. The descent is made approximately towards the centre of the thread, but is then oriented on one side only, with each new pass alternating flanks..
