#Lathe Drill Cycle Parameters

Use this tab to create a lathe drill toolpath along the part’s centerline. You do not need to create or chain any geometry to create the toolpath. First, define the dimensions of the hole, using the picture as a guide. Then, select a drill cycle and enter the drilling parameters.

#Depth

Determines the location of the bottom of the drill hole. This can be measured using Absolute or Incremental values and is calculated differently for each. Click Depth and select a point on the geometry or enter a value.

#Absolute

Measures the position relative to the origin.

#Incremental

Measures the position relative to the drill point.

#Depth calculator button

Click to open the Depth Calculator so that you can calculate the proper drilling depth based on a finished diameter and drill size, for example, when countersinking a hole.

#Drill point

Enter the coordinates of the drill point in the X and Z fields or click to select a point from the graphics window.

#Clearance

A safe point along the drilling axis to which the tool rapids before approaching the part. This can be measured using Absolute or Incremental values and is calculated differently for each. If drilling towards the left, this value must be greater or equal to the retract value. If drilling to the right, the value must be less than or equal to the retract value. Click to select a point on the geometry or enter a value.

#From stock

Measures an incremental position relative to the current stock plane. Enabled only if a stock boundary is defined in the machine group properties. If the stock definition changes, this point is recomputed when you regenerate the drilling operation.

#Retract

When choosing incremental, the value you enter determines how far above the top of the hole the tool stops rapidly and begins traveling at the programmed feed rate towards the stock. This can be measured using Absolute or Incremental values and is calculated differently for each.

When choosing Absolute, the value you enter determines how far from the origin the tool stops rapidly and begins traveling at the given feed rate towards the stock. The tool travels at the feed rate directly above the drill point until it reaches the bottom of the hole.

If you have defined a stock boundary in the Machine Group Properties and choose Incremental, the From stock option is enabled. See the previous From stock definition.

#Cycle

Select a drill cycle from the drop-down list. Only cycles which have been defined in the active control definition appear on this list.

#First peck

Sets the depth for the first-peck move, which plunges in and out of the material to clear and break chips.

#Subsequent peck

Sets the depth for all peck moves after the first peck. Peck moves plunge in and out of the material to clear and break chips.

#Peck clearance

Sets the depth that the tool rapids to between peck moves. The value is added to the previously drilled peck depth. This option is enabled or disabled depending on the selected drill cycle and whether the post supports peck clearance for that drill cycle.

#Retract amount

Determines the distance the tool moves away from the face of the part before it moves to the start of the next cut.

#Dwell

Sets the amount of time in seconds that the tool remains at the bottom of a drilled hole. If using a peck drill cycle, the dwelling value only applies to the final depth.

#Shift

Sets the distance that a boring bar tool moves away from the wall of the toolpath before retracting. This helps prevent gouging. This option only applies to bore bar drill cycles.

#Drill tip compensation

Select to adjust the drilling depth so that the drill fully breaks through the material by the Breakthrough amount.

#Breakthrough amount

Determines how far the tool goes past the final depth. Ensures that the full diameter of the tool breaks through the bottom of the stock.
