60 First Steps with the iTNC 530

1.2 Machine Switch-On

Acknowledge the power interruption and move to the reference points

Switch-on and crossing the reference points can vary depending on the machine tool. Your machine manual provides more detailed information.

U Switch on the power supply for control and machine. The TNC starts

the operating system. This process may take several minutes. Then the TNC will display the message “Power interruption.”

U Press the CE key: The TNC converts the PLC

program

U Switch on the control voltage: The TNC checks

operation of the emergency stop circuit and goes into the reference run mode

U Cross the reference points manually in the displayed

sequence: For each axis press the machine START button. If you have absolute linear and angle encoders on your machine there is no need for a reference run

The TNC is now ready for operation in the Manual Operation mode.

62 First Steps with the iTNC 530

Create a new program/file management

U Press the PGM MGT key: the TNC displays the file

management. The file management of the TNC is arranged much like the file management on a PC with the Windows Explorer. The file management enables you to manipulate data on the TNC hard disk

U Use the arrow keys to select the folder in which you

want to open the new file

U Enter a file name with the extension .H: The TNC then

automatically opens a program and asks for the unit of measure for the new program. Please note the restrictions regarding special characters in the file name (see “File names” on page 122)

U To select the unit of measure, press the MM or INCH

soft key: The TNC automatically starts the workpiece blank definition (see “Define a workpiece blank” on page 64)

The TNC automatically generates the first and last blocks of the program. Afterwards you can no longer change these blocks.

Program layout

NC programs should be arranged consistently in a similar manner. This makes it easier to find your place and reduces errors.

Recommended program layout for simple, conventional contour machining

1 Call tool, define tool axis 2 Retract the tool 3 Pre-position the tool in the working plane near the contour starting

point

4 In the tool axis, position the tool above the workpiece, or pre-

position immediately to workpiece depth. If required, switch on the spindle/coolant

5 Move to the contour 6 Machine the contour 7 Leave the contour 8 Retract the tool, end the program

Introduction

2.1 The iTNC 530

HEIDENHAIN TNC controls are workshop-oriented contouring controls that enable you to program conventional machining operations right at the machine in an easy-to-use conversational programming language. They are designed for milling, drilling and boring machines, as well as for machining centers. The iTNC 530 can control up to 18 axes. You can also change the angular position of up to 2 spindles under program control.

An integrated hard disk provides storage for as many programs as you like, even if they were created off-line. For quick calculations you can

2.1 The iTNC 530

call up the on-screen pocket calculator at any time. Keyboard and screen layout are clearly arranged in such a way that the

functions are fast and easy to use.

Programming: HEIDENHAIN conversational, smarT.NC and ISO formats

The HEIDENHAIN conversational programming format 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 FK free contour programming performs the necessary calculations automatically. Workpiece machining can be graphically simulated either during or before actual machining.

The smarT.NC operating mode offers TNC beginners an especially simple possibility to quickly and without much training create structured conversational dialog programs. Separate user documentation is available for smarT.NC.

It is also possible to program the TNCs in ISO format or DNC mode. You can also enter and test one program while the control is running

another.

Compatibility

The TNC can run all part programs that were written on HEIDENHAIN controls TNC 150 B and later. In as much as old TNC programs contain OEM cycles, the iTNC 530 must be adapted to them with the PC software CycleDesign. For more information, contact your machine tool builder or HEIDENHAIN.

2.5 Window Manager

The machine tool builder determines the scope of function and behavior of the window manager. The machine tool manual provides further information.

The TNC features the Xfce window manager. Xfce is a standard application for UNIX-based operating systems, and is used to manage graphical user interfaces. The following functions are possible with the window manager:

 Display a task bar for switching between various applications (user

interfaces).

 Manage an additional desktop, on which special applications from

your machine tool builder can run.

 Control the focus between NC-software applications and those of

the machine tool builder.

 The size and position of pop-up windows can be changed. It is also

possible to close, minimize and restore the pop-up windows.

The TNC shows a star in the upper left of the screen if an application of the window manager or the window manager itself has caused an error. In this case, switch to the window manager and correct the problem. If required, refer to your machine manual.

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

3-D touch 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  Measure and inspect tools

All of the touch probe functions are described in the User’s Manual for Cycles. Please contact HEIDENHAIN if you require a copy of this User’s Manual. ID: 670 388-xx.

Note that HEIDENHAIN generally does not accept liability for the function of the touch probe cycles unless you use HEIDENHAIN touch probes!

TS 220, TS 640 and TS 440 touch trigger probes

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

The TS 640 (see figure) and the smaller TS 440 feature infrared transmission of the triggering signal to the TNC. This makes them 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 control, which stores the current position of the stylus as the actual value.
