How to use this manual
This manual describes functions and fezitures aYailr;tble on the
TNC370fromMCso%re number280K?OOf.
This manual describes all available TNC 370 functions.
For information on your machine tool refer to the machine tool manual.
The NC beginner can use the manual as a workbook. The first part of the
manual deals with the basics of NC technology and describes the TNC
370 functions. It then introduces the techniques of conversational pro-
gramming. Each new function is thoroughly described when it is first
introduced, and the numerous examples can be tried out directly on the
control. The NC beginner should work through this manual from beginning
to end to ensure that he is capable of fully exploiting the features of this
powerful tool.
For the NC expert, this manual serves as a comprehensive reference
work. The table of contents and cross references enable him to quickly
find the topics and information he needs. Easy-to-read dialog flowcharts
show him how to enter the data required for each function.
The dialog flow charts consist of sequentially arranged instruction boxes.
Each key is illustrated next to an explanation of its function to aid the
beginner when he is performing the operation for the first time. The
experienced user can use the key sequences illustrated in the left part of
the flowchart as a quick overview. The TNC dialogs are always presented
on a gray background.
