10: Configuring a Workpiece Offset

The workpiece offset file contains three values, used to describe the

location of your workpiece datum. They determine how much you

want to shift the zero reference position of the CNC machine along

the X, Y and Z axes.

However, if your CNC file uses two or more tool profiles, the

workpiece offset file will not account for the difference in length

between the tools. To achieve this, you must also configure a tool

offset value for each tool profile you intend to use (see the next

page).

Before you can begin entering the workpiece offset values, you must

position the tool over your workpiece datum. Move the tool so its

cutting tip just touches your chosen workpiece datum position, as

shown in the diagram below. Take care not to damage the cutting

tip, when manoeuvring the tool.

A clearer view of the

cutting tool tip can be

obtained by raising the

front brush guard.

Tip

In this example, the workpiece datum is set at the front left

upper corner of the billet, held in place using the vacuum table.

Alternatively, if the billet was a large, thin, flat piece of material,

a small mark could be made on the surface to identify the

proposed location of the workpiece datum.
