About This Manual
If you're new to TNC, you can use the operating instructions as a
step-by-step workbook. This part begins with a short introduction to
the basics of coordinate systems and position feedback, and pro-
vides an overview of the available features. Each feature is explained
in detail, using an example — so you won't get “lost” too deeply in
the theory. As a beginner you should work through all the examples
presented.
The examples are intentionally brief; it generally won't take you
longer than 10 minutes to enter the example data.
If you're already proficient with TNC, you can use the operating
instructions as a comprehensive review and reference guide. The
clear layout and the subject index make it easy to find the desired
topics.

Prompt

continues on the next page.
A prompt appears with some actions (not always) at the top of the
screen.
If two flowcharts are divided by a broken line, and words by “or,”

press the correct keys.
