How to use this manual

This manual describes functions and fezitures

TNC 370 from MC so%re

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 programming. 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.

Introduction

1.1 TNC 370

Control The TNC 370 is a shop-floor programmable contouring control for milling

machines with up to four axes. The spindle can be rotated to a given

angular stop position (oriented spindle stop).

Visual Display Unit and Operating Panel

The flat luminescent monochrome screen clearly displays all information

necessary for operating the TNC 370. The keys on the operating panel are grouped according to their functions. This simplifies operating and programming the control. The following keyboard units are available:

TE 370 with machine operating keys

(such as NC start, NC stop, coolant on/off)

TE 371 without machine operating keys

Programming

The TNC 370 is programmed directly at the machine with the easy-to-

use HEIDENHAIN plain language dialog format. Programming in IS0 format is also possible, and is described in the TNC 370 User’s Manual for IS0 Programming.

Graphics The graphic simulation feature enables you to test programs before

actual machining. Several types of graphic representation can be selected.

Compatibility The TNC 370 can execute any part program that was created on a TNC

150B or subsequent HEIDENHAIN control.

1.1 TNC 370

Soft key structure

Most of the TNC 370 functions are activated and programmed by soft keys. A soft key is a key whose function is controlled by software. The individual soft key functions are arranged in a “menu tree” structure. This makes it possible for a single hardware key to perform a multitude of different functions. The following section shows the menu tree of the TNC 370 and will help you-particularly in the beginning-to select a specific function.
