Dwell

Definition

Ability to program dwell during the toolpath, according to several parameters:

• Dwell Depth

• Dwell Unit

• Dwell

• Final Dwell

Settings

• Choose first the unit of the dwell: it can be expressed either in seconds or in revolution.

• Then you can define the Dwell Depth, which is the distance between two dwells.

• Dwell is the value in seconds or revolution, the code is often G04 with a letter (X or U for Fanuc, F for Num for example).

• Final Dwell enables to define a different value at the end, to make a better finish at last pass.

The dwell defined are displayed on the screen with the hourglass symbol as shown on the picture below.

In this example: Dwell Depth = 5mm (at diameter, x = 126.6, x = 116.6, x = 96.6) Dwell Unit is seconds Dwell = 0.2s Final Dwell = 0.5s

Special case for Direct, Z Level and Wtype Grooving operations.

The dwell defined in strategy is not applied on all the toolpath for those three operations. In a way, we can consider that the roughing passes are decomposed in two paths:

• ‘roughing' passes: vertical plunges are done by the tool and there the dwell can be applied.

• ‘pre-finishing' pass: the tool realizes one path on the profile after each roughing plunge. This pass is triggered by the parameter ‘Profile Machining’.
