Presetting
The Preset function has been explained previously in this manual (See
"Presetting" on page 39). The explanation, and examples on those
pages are based on a mill application. The basics of those explanations
are the same for turning applications with two exceptions; Tool
Diameter Offsets (R+/-), and Radius vs. Diameter inputs.
Tool diameter offsets have no applications with turning tools, so this
functionality is not available while doing turning presets.
While doing turning, input values can be either radius, or diameter
values. It is important to be sure the units being entered for the preset
agree with the state that the display is currently using. A diameter
value is shown with a Ø symbol. The state of the display can be
changed using the RX soft key (see below).
RX (Radius/Diameter) Soft Key
Drawings for lathe parts usually give diameter values. ND 522/523 can
display either the radius, or the diameter for you. When the diameter
is being displayed, the diameter symbol (Ø) is shown next to the
position value.
Example: Radius display, position 1 X = 20 mm
Diameter display, position 1 X = Ø 40 mm
Press the RX soft key to switch between radius
display, and diameter display.
