Presetting. HEIDENHAIN ND 522 - 2-2011, ND 523

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.
