TNC Models, Software and

Features

This manual describes functions and features provided by the TNCs with the following NC software number.

TNC Model	NC Software No.
TNC 410	286 060-xx
TNC 410	286 080-xx

The machine tool builder adapts the useable features of the TNC to his machine by setting machine parameters. Therefore, some of the functions described in this manual may not be among the features provided by your machine tool.

TNC functions that may not be available on your machine include:

■Probing function for the 3-D touch probe

■Digitizing option

■Tool measurement with the TT 120

■Rigid tapping

Please contact your machine tool builder to become familiar with the individual implementation of the control on your machine.

Many machine manufacturers, as well as HEIDENHAIN, offer programming courses for the TNCs. We recommend these courses as an effective way of improving your programming skill and sharing information and ideas with other TNC users.

Location of use

The TNC complies with the limits for a Class A device in accordance with the specifications in EN 55022, and is intended for use primarily in industrially-zoned areas.

Introduction

1.1 The TNC 410

1.1 The TNC 410

HEIDENHAIN TNC controls are shop-floor programmable contouring controls for milling, drilling and boring machines, as well as machining centers with up to four axes. You can program conventional milling, drilling and boring operations right at the machine with the easily understandable interactive conversational guidance. You can also change the angular position of the spindle under program control.

Keyboard and screen layout are clearly arranged in a such way that the functions are fast and easy to use.

Programming: HEIDENHAIN conversational and ISO formats

HEIDENHAIN conversational programming is an especially easy method of writing programs. Interactive graphics illustrate the individual machining steps for programming the contour. If a production drawing is not dimensioned for NC, the HEIDENHAIN FK free contour programming carries out the necessary calculations automatically. Workpiece machining can be graphically simulated during test run. It is also possible to program in ISO format or DNC mode.

You can enter a program while the TNC is running another.

Compatibility

The TNC can execute all part programs that were written on HEIDENHAIN controls TNC 150 B and later.

2	1 Introduction

1.2 Visual Display Unit and Keyboard

Visual display unit

The TNC is available with either a color CRT screen (BC 120) or a TFT flat panel display (BF 120. The figures at right show the keys and controls on the BC 120 (upper right) and the BF 120 (middle right).

Header

When the TNC is on, the selected operating modes are shown in the screen header.

Soft keys

In the footer the TNC indicates additional functions in a soft-key row. You can select these functions by pressing the keys immediately below them . The lines immediately above the soft-key row indicate the number of soft-key rows that can be called with the black arrow keys to the right and left. The line representing the active soft-key row is highlighted.

The BC 120 is sensitive to magnetic and electromagnetic noise, which can distort the position and geometry of the picture. Alternating fields can cause the picture to shift periodically or to become distorted.

Screen layout

You select the screen layout yourself: In the PROGRAMMING AND EDITING mode of operation, for example, you can have theTNC show program blocks in the left window while the right window displays programming graphics.You could also display help graphics for cycle definition in the right window instead, or display only program blocks in one large window.The available screen windows depend on the selected operating mode.

To change the screen layout:

Press the SPLIT SCREEN key: The soft-key row shows the available layout options.

<

Select the desired screen layout.

1.3 Modes of Operation

TheTNC offers the following modes of operation for the various functions and working steps that you need to machine a workpiece:

Manual Operation and Electronic

The Manual Operation mode is required for setting up the machine tool. In this operating mode, you can position the machine axes manually or by increments and set the datums.

The Electronic Handwheel mode of operation allows you to move the machine axes manually with the HR electronic handwheel.

Soft keys for selecting the screen layout

The same selection is available as in the Positioning with MDI mode. TheTNC always shows the positions at left in the divided screen.

1.5Accessories: HEIDENHAIN 3-D Touch Probes and Electronic Handwheels

3-DTouch Probes

With the various HEIDENHAIN 3-D touch probe systems you can:

■Automatically align workpieces

■Quickly and precisely set datums

■Measure the workpiece during program run

■Digitize 3-D surfaces (option), and

■Measure and inspect tools

TS 220 and TS 630 touch trigger probes

These touch probes are particularly effective for automatic workpiece alignment, datum setting, workpiece measurement and for digitizing. The TS 220 transmits the triggering signals to the TNC via cable and is a cost-effective alternative for applications where digitizing is not frequently required.

The TS 630 features infrared transmission of the triggering signal to the TNC. This makes it highly convenient for use on machines with automatic tool changers.

Principle of operation: HEIDENHAIN triggering touch probes feature a wear resisting optical switch that generates an electrical signal as soon as the stylus is deflected. This signal is transmitted to the TNC, which stores the current position of the stylus as an actual value.

During digitizing the TNC generates a program containing straight line blocks in HEIDENHAIN format from a series of measured position data. You can then output the program to a PC for further processing with the SUSA evaluation software. This evaluation software enables you to calculate male/female transformations or correct the program to account for special tool shapes and radii that differ from the shape of the stylus tip. If the tool has the same radius as the stylus tip you can run these programs immediately.

TT 120 tool touch probe for tool measurement

The TT 120 is a triggering 3-D touch probe for tool measurement and inspection. Your TNC provides three cycles for this touch probe with which you can measure the tool length and radius automatically— either with the spindle rotating or stopped.

The TT 120 features a particularly rugged design and a high degree of protection, which make it insensitive to coolants and swarf. The triggering signal is generated by a wear-resistant and highly reliable optical switch.

HR electronic handwheels

Electronic handwheels facilitate moving the axis slides precisely by hand. A wide range of traverses per handwheel revolution is available. Apart from the HR 130 and HR 150 integral handwheels, HEIDENHAIN also offers the HR 410 portable handwheel.

Manual Operation and Setup

2.1 Switch-On

2.1 Switch-On

Switch-on and traversing the reference points can vary depending on the individual machine tool. Refer to your machine manual.

Switch on the power supply for control and machine.

The TNC automatically initiates the following dialog

<

The TNC memory is automatically checked.

<

TNC message that the power was interrupted

— clear the message.

<

The PLC program of the TNC is automatically compiled.

<

Switch on the control voltage.

The TNC checks the functioning of the

EMERGENCY STOP circuit.

!

<

Cross the reference points in any sequence: Press and hold the machine axis direction button for each axis until the reference point has been traversed, or

Cross the reference points with several axes at the same time: Use soft keys to select the axes (axes are then shown highlighted on the screen), and then press the machine START button.

The TNC is now ready for operation in the

Manual Operation mode.

14	2 Manual Operation and Setup

2.2 Moving the Machine Axes

Traversing with the machine axis direction buttons is a machine-dependent function. Your machine manual provides more detailed information.

To traverse with the machine axis direction buttons:

Select the Manual Operation mode.
