Sets the screen layout You select the screen layout yourself: In the PROGRAMMING AND EDITING mode of operation, for example, you can have the TNC show program blocks in the left window while the right window displays programming graphics. You could also display the program structure in the right window instead, or display only program blocks in one large window.
Page 83: Operating Panel
The functions of the individual keys are described on the inside front cover. Some machine manufacturers do not use the standard operating panel from HEIDENHAIN. Please refer to your machine manual in these cases. Machine panel buttons, e.g. NC START or NC STOP, are also described in the manual for your machine tool.
Page 84: Operating Modes
2.3 Operating Modes Manual Operation and Electronic Handwheel The Manual Operation mode is required for setting up the machine tool. In this mode of operation, you can position the machine axes manually or by increments, set the datums, and tilt the working plane. The Electronic Handwheel mode of operation allows you to move the machine axes manually with the HR electronic handwheel.

Page 104: Polar Coordinates
Polar coordinates If the production drawing is dimensioned in Cartesian coordinates, you also write the NC program using Cartesian coordinates. For parts containing circular arcs or angles it is often simpler to give the dimensions in polar coordinates. While the Cartesian coordinates X, Y and Z are three-dimensional and can describe points in space, polar coordinates are two-dimensional and describe points in a plane.
Page 105: Absolute And Incremental Workpiece Positions
Y = 10 mm Y = 10 mm Absolute and incremental polar coordinates Absolute polar coordinates always refer to the pole and the reference axis. Incremental coordinates always refer to the last programmed nominal position of the tool. HEIDENHAIN iTNC 530...
Page 106: Setting The Datum
The fastest, easiest and most accurate way of setting the datum is by using a 3-D touch probe from HEIDENHAIN. See “Setting the Datum with a 3-D Touch Probe” in the Touch Probe Cycles User’s Manual.
Page 107: Creating And Writing Programs
3.2 Creating and Writing Programs Organization of an NC program in HEIDENHAIN Conversational A part program consists of a series of program blocks. The figure at right illustrates the elements of a block. The TNC numbers the blocks in ascending sequence.

The tool retains the Z coordinate and moves in the XY plane to the position X=70, Y=50 (see figure). Three-dimensional movement The program block contains three coordinates. The TNC thus moves the tool in space to the programmed position. Example: L X+80 Y+0 Z-10 HEIDENHAIN iTNC 530...
Page 206 Entering more than three coordinates The TNC can control up to 5 axes simultaneously (software option). Machining with 5 axes, for example, moves 3 linear and 2 rotary axes simultaneously. Such programs are too complex to program at the machine, however, and are usually created with a CAM system.

Graphics during FK programming If you wish to use graphic support during FK programming, select the PROGRAM + GRAPHICS screen layout (see “Programming and Editing” on page 85). Incomplete coordinate data often is not sufficient to fully define a workpiece contour. In this case, the TNC indicates the possible solutions in the FK graphic.

Converting FK programs into HEIDENHAIN conversational format The TNC features two possibilities for converting FK programs to plain-language programs: Convert the program so that the program structure is maintained (program-section repeats and subprogram calls).

Page 257 Programming: Data Transfer from DXF Files...
Page 258 7.1 Processing DXF Files (Software Option) Function DXF files created in a CAD system can be opened directly by the TNC, in order to extract contours or machining positions, and save them as conversational programs or as point files. Plain-language programs acquired in this manner can also be run by older TNC controls, since these contour programs contain only L and CC/C blocks.
Page 259: Opening A Dxf File
Select the desired DXF file, and load it with the ENT key. The TNC starts the DXF converter and shows the contents of the DXF file on the screen. The TNC shows the layers in the left window, and the drawing in the right window. HEIDENHAIN iTNC 530...

Page 262: Layer Settings
Layer settings As a rule, DXF files contain multiple layers, with which the designer organizes the drawing. The designer uses the layers to create groups of various types of elements, such as the actual workpiece contour, dimensions, auxiliary and design lines, shadings, and texts. So that as little unnecessary information as possible appears on the screen during selection of the contours, you can hide all excessive layers contained in the DXF file.

Page 296 Programming notes You can mix Q parameters and fixed numerical values within a program. Q parameters can be assigned numerical values between 999 999 999 and +999 999 999, meaning that up to nine digits plus the algebraic sign are permitted. You can set the decimal point at any position. Internally, the TNC can calculate up to a range of 57 bits before and 7 bits after the decimal point (32-bit data width corresponds to a decimal value of 4 294 967 296).

Page 406: Basic Rotation
Basic rotation The basic rotation function enables you to compensate a workpiece misalignment. The effect corresponds to the basic rotation function that you can define in the manual mode with the probing functions. The TNC synchronizes the values entered in the basic rotation menu or the ROT column of the preset table with the fillable form.

Superimposed mirroring With the superimposed mirroring function you can mirror all active axes. The mirrored axes defined in the form work in addition to the values already defined in the program through Cycle 8 (mirroring). Remember that you may have to return to the contour after activation of this function.

Page 410: Handwheel Superimposition
Handwheel superimposition The handwheel superimposition function enables you to use the handwheel to move the axes while the TNC is running a program. In the Max. val. column you define the maximum distance by which you can move the axis by handwheel. As soon as you interrupt the program run (control-in-operation signal is off), the TNC shows the distances actually moved in each axis in the actual value column.

Defining the AFC basic settings You enter the settings for the TNC feed rate control in the table AFC.TAB, which must be saved in the root directory TNC:\.

Through the functions that can be defined by the machine tool builder you can define a percentage value for wear or breakage detection with respect to the rated power.

Page 625: Software For Data Transfer
For transfer of files to and from the TNC, we recommend using the HEIDENHAIN TNCremoNT data transfer software. With TNCremoNT, data transfer is possible with all HEIDENHAIN controls via the serial interface or the Ethernet interface. You can download the current version of TNCremoNT free of charge from the HEIDENHAIN Filebase (www.heidenhain.de, <Services and Documentation>,...
Page 626 Data transfer between the TNC and TNCremoNT Before you transfer a program from the TNC to the PC, you must make absolutely sure that you have already saved the program currently selected on the TNC. The TNC saves changes automatically when you switch the mode of operation on the TNC, or when you select the file manager via the PGM MGT key.
Page 627: Ethernet Interface
The maximum cable length between TNC and a node depends on the quality grade of the cable, the sheathing and the type of network (100BaseTX or 10BaseT). If you connect the TNC directly with a PC, you must use a crossed cable. HEIDENHAIN iTNC 530...
