Drilling

Drilling is used to drill holes at set locations on your stock.

The center of the drilling locations are defined with points, you will need to place these points into the following layer in the Rhino document:

KaroroCAM/Drilling

Tool Shape

For the Drilling toolpath only the Drill Bit is available:

Tool Diameter

Sets the diameter of your tool bit in mm.

Tool Number

Select Tool number that matches the tool spec'd in your tool path - mostly important for machines with auto tool change ability.

Spindle Speed

Drilling Depth

Drilling Depth Positions

Selects the reference position for the drilling depth. Can be:

Selected Points - the cutting depth will be referenced to the points in the Drilling layer in the Rhino document. These can all be at different Z heights

Stock Top - Drilling depth is referenced to the top of the current stock - all drilling will be done to the same depth

Stock Bottom - Drilling depth is referenced to the bottom of the current stock - all drilling will be done to the same depth

NOTE: Drilling Depth Offset is a Z offset from this selection

Drilling Depth Offset

Offset in mm in the Z direction from the selected Drilling Depth Position of the final drilling depth. 

Multiple Depths

USE MULTIPLE DEPTHS

Check this box to enable multiple depth engraving paths

NOTE: When Multiple Depths is selected in Drilling the drill bit will be fully withdrawn from stock on after each pass to the multiple depth positions.

Max Step Down

Maximum step down in mm per pass when doing multiple depth drilling. 

NOTE: If the total cutting depth (Stock top - Drilling Depth Position + Drilling Depth Offset) is not an even division by this number the deepest pass will be less than this number.
