Drilling Type

Cycle: Drilling

Definition

This function allows to carry out three types of drilling:

	Simple: it is a one pass drilling cycle. The ISO code generates a simple hole cycle (usually a G81).
	Deburring: it is a several passes drilling cycle with tool back off. The ISO code generates a cycle corresponding to a drilling with deburring.
	Chip break.: it is a several passes drilling cycle with a slight draw-back of the tool. The ISO code generates a cycle corresponding to a drilling with chip breaking.

For Simple type, the Leadin Depth can be defined for which the Leadin for the drilling cycle is carried out at a different feedrate. The Leadin Feedrate is defined in the Technology page.

The Leadin Rotation speed can also be defined in the Technology page. In the Strategy page, the Leadin Depth must have a value, else Leadin Feedrate and Leadin rotation are grayed out.

If Deburring or Chip break. is selected, more parameters appear, listed below.

Depending on the option selected, the availability of certain parameters varies, verify accordingly.

• Deburring Distance: to retract further and facilitate the retract chip and the coolant fluid.

• Z Step: this is the Z increment between each pass. It corresponds to the cutting of the total depth. If the incremental depth is greater than the maximum depth of pass of the tool, there is a warning message

• Dwell: the value corresponds to the dwell in second on each increment.

• Depth of Last Pass.: it is the value of the last pass. If the first increment value is different from the last increment, the cycle is done in decreasing passes.

• Incr. retract.: it is the retraction distance between each incremental plunging.
