Inclined Machining
The EM250 Line-hole calculator operates on the work-to-zero principle for the machining an inclined plane.
To achieve these calculations the DRO needs to be configured with the following parameters:
● Plane to machine
● Angle
● Max Cut step size
Plane options: XY, XZ, YZ
X+
Y+
+
Z+
Angles are positive clockwise
To best demonstrate these methods let us consider the part below as by way of example.
Parameter Value
Plane XZ
Angle of Line 30o
Max. Cut 0.5mm
30o
0.5mm
The finer the step the
smoother the finish
ABS
Move the tool to the start position of the incline to be machined. You may wish to set this as a datum but it could be
any value or even an SDM point. Then enter the function using the key.
INCL XY
Navigate to the required plane.
INCL YZ INCL XZ

Navigation keys
In this example in order to machine a 30o angle
for every 0.5mm in Z we would need to move
0.865mm steps in X.

The parameter values programmed in to the Line-Hole function are saved to the DRO memory so that they
can be recalled even after the DRO power is turned off. Simply reselect the Line-Hole function and you can
then simply check the parameters, or edit them as may be required for a new pattern.
