LATHE FUNCTIONS
Z + Z > Z
The summing function allows the sum of two selected axes to be displayed. The axes are selected in Set-
Up see section 3.2. Summing is available on the 3-Axis version only.
50.000
In the following example it assumes that the bed (Z) and
compound (Z') are the selected axes.

Press the Summing key [ 1+1 ] to select the Summing
function. The selection of the summed axes is made in
Set-Up (Refer to Section 3.2).
The message screen displays Z+Z'>Z, and the Z display
shows the sum of the two axes.

Pressing the [ 1+1 ] key returns to the original (non
summed) axes display.
NOTE: Axis displays may be zeroed or loaded with a
value in the summed mode. The underlying X
or Z values are altered to suit.
When a Lathe is fitted with ascale on the compound, vectoring provides a true reading of the tool path when
it is angled at any position from 0
° - 90° relative to the part. Vectoring is, calculated using the formulas (Z +
Z
l
cosΘ) and (X + Z
l
sinΘ) where Z represents the compund scale reading.
Vectoring has to be initially selected in the Set-Up routine. (Refer to Section 3.2)
