New Functions with NC Software 340 49x-07 

—The iTNC 530 Makes Working with the Machine Even Easier 

The iTNC 530 from HEIDENHAIN has 

proven itself for years as a versatile 

contouring control for milling, drilling and 

boring machines as well as machining 

centers. Along with HEIDENHAIN’s plainlanguage 

conversational programming for 

the shop floor, the iTNC 530 is 

characterized by many useful functions 

and innovative features. To name just a 

few: 

• Exact tool guidance for five-axis 

machining 

• Simple tilting of the working plane 

• Practice-oriented setup functions 

• Very high contour accuracy for HSC 

milling 

• Extensive fixed cycles 

• Helpful programming support through 

unambiguous function keys, free contour 

programming and help graphics 

• Upwardly compatible part programs 

• External programming and fast data 

transfer 

The success story of the iTNC 530 also 

includes smarT.NC—the new operating 

mode from HEIDENHAIN. It represents 

another successful step toward more userfriendliness 

in a shop-floor programming 

interface. Well-structured input forms, 

straightforward graphic support, and 

comprehensive help texts combine with 

the easy-to-use pattern generator to form 

a compelling programming environment.

New functions for the iTNC 530 

Of course there is always potential for 

new development, improvement and 

simplification. The NC software 340 49x-07 

for the iTNC 530 includes a series of new 

functions for machine tool builders and 

users. These functions make it even easier 

to work with the control, and they also 

make operation of the machine more safe. 

The most important new functions are: 

• smarT.NC wizard for inserting smarT.NC 

units in conversational programs 

• Cycle for interpolation turning (option) 

• Cycle for machining 3-D contour trains 

• Engraving cycle 

Error fixes, new and improved functions 

and options 

As of NC software 340 49x-02, error fixes 

have been separated from software 

improvements. Updates of NC software 

usually contain only error fixes. 

New functions certainly offer added value 

regarding user-friendliness and operational 

reliability. Naturally you also have the 

opportunity to purchase these new 

functions after a software update: These 

new and improved functions are offered 

as “feature upgrades,” and are enabled via 

the Feature Content Level option. 

If, for example, a control is to be upgraded 

from NC software 340 49x-02 to 340 49x-07, 

the functions identified with “FCL xx” in 

the following tables are only available if the 

feature content level is set from 02 to 04. 

Of course the current feature content level 

also includes the upgrade functions of the 

previous NC software versions. 

All of the options included in the 

respective NC software can be purchased, 

no matter which feature content level you 

have.

smarT.NC Goes Conversational 

—Inserting smarT.NC Units in Conversational Programs 

The new smarT.NC wizard completely 

unifies the worlds of smarT.NC and 

conversational programming. The 

strengths of both worlds are now available 

in a single user interface. The full flexibility 

of conversational programming, based on 

NC blocks, can now be combined at any 

location with the fast, form-based 

workstep programming method of 

smarT.NC. Programming goes much 

quicker particularly in combination with the 

DXF converter or the graphically supported 

definition of any machining patterns. All 

other machining units available in smarT.NC 

also simplify the creation of conversational 

programs. 

When inserting a smarT.NC unit, the TNC 

displays the conversational program in the 

familiar manner on the left side of the 

screen. On the right side the TNC shows 

the smarT.NC form with the corresponding 

input fields specific to the respective unit. 

The help graphic belonging to each input 

field is shown in the bottom part of the 

screen. When the form is saved, the TNC 

inserts all conversational blocks necessary 

for the defined machining operation. 

Changes can later be made either in the 

form or directly in the appropriate NC block. 

The operator can decide himself which 

method he prefers. 

3

The Future is Now 

—Graphic Selection of Contours and Contour Sections (Option) 

For several years now the iTNC 530 has 

been able to select contours from DXF 

files. Now the DXF converter can also open 

conversational programs that were created 

externally in CAM systems. 

The DXF converter graphically displays the 

tool paths generated in the CAM system. 

You can select parts of the contour and 

save them as separate NC programs. This 

is especially helpful, for example, when 

you need to rework parts of contours with 

a smaller tool, or even if you just want to 

rework some parts of a 3-D shape. This 

function saves you a trip to the CAM office, 

and can be performed at any time directly 

on the iTNC. 

You can then machine this newly created 

NC program directly or in combination with 

the TNC’s contour train cycles.

Safe Machining 

— Option for Integrated Dynamic Collision Monitoring (DCM): 

Improvements 

Dynamic collision monitoring (DCM) 

has now proven itself on approximately 

4 500 machines throughout the world. 

Since being introduced in 2005, this 

function has become an increasingly 

important instrument in reducing costly 

machine downtimes and relieving the 

machine operator, especially when 

manually moving the machine axes. During 

manual operation, the iTNC automatically 

reduces the speed if two collision objects 

come too close to each other, and issues 

an error message if a collision is imminent. 

The iTNC not only monitors the permanent 

machine components defined by the 

machine tool builder, but also fixtures, 

tools and tool carriers. 

Automatic activation/deactivation of 

fixture situations 

With the new NC functions SEL FIXTURE 

and FIXTURE SELECTION RESET you can 

activate or deactivate previously saved 

fixture situations in automatic operation. 

Specific fixtures can also be activated for 

each NC program from pallet tables. This 

increases safety and reliability in 

automated production. 

Tool carrier management 

In order to take tool holders into account 

for collision monitoring, you can assign the 

corresponding collision body to each tool in 

the tool table. There is now graphic support 

for selection of the collision body: the TNC 

shows a preview of the collision body to be 

selected. 

Collision monitoring for multiple task 

tools 

If you use indexed multiple task tools, 

the TNC now also monitors these tasks 

automatically and correctly, and adapts the 

kinematics view correspondingly. 

5

Machining Flexibly 

—Interpolation Turning (Option) 

In interpolation turning the cutting edge of 

the tool moves on a circle, with the cutting 

edge always oriented to the center of the 

circle. By varying the circle radius and the 

axial position, any rotationally symmetric 

objects can be produced in any working 

plane. 

With the new Cycle 290 INTERPOLATION 

TURNING, the iTNC 530 can create a 

rotationally symmetric step in the active 

working plane, which is defi ned by the 

starting and end point. The center of 

rotation is the tool location in the working 

plane at the time the cycle is called. The 

rotational surfaces can be inclined or 

rounded relative to each other. 

This cycle can only be used for fi nishing. 

Roughing operations with multiple steps 

are not possible. The machining strategy 

can be chosen fl exibly: from the outside in 

or vice versa, and also from top to bottom 

or vice versa. This results in four different 

machining strategies, which are distributed 

over the four quadrants. 

6

—Peripheral Milling with the New Contour Train Cycle 

Special demands are in force during 

peripheral milling of cutting and bending 

tools, particularly for large-scale mold 

making for the automobile industry. The 

contour edges are generated by CAM 

systems, and as a rule do not just contain 

coordinates for the machining plane, but 

also for the tool-axis direction. Of 

importance here is that the cutting or 

bending edge does not have a constant 

Z height, but can vary greatly on a 

workpiece. 

The new Cycle 276 CONTOUR TRAIN 3D 

can machine such 3-D contours very easily. 

Similar to Cycle 25 CONTOUR TRAIN, 

which is two-dimensional, the contour to 

be machined must be defined in a 

subprogram. You specify the approach 

behavior, machining mode and radius 

compensation with Cycle 270 CONTOUR 

TRAIN DATA, and then call Cycle 276. The 

3-D contour train can be machined with or 

without an infeed, depending on whether 

one has been defined. 

The 3-D contours to be machined can be 

created very easily if they can be loaded 

from existing NC programs that were 

generated by a postprocessor. This applies 

in particular if a smaller tool must be used 

to rework specific areas. An enhancement 

was implemented for this in the DXF 

converter, making it possible to load 

contours or parts of contours from 

conversational programs (see page 4). 

7

New Programming Functions 

—Miscellaneous 

New engraving cycle 225 

The new engraving cycle 225 is a 

convenient method for producing texts or 

serial numbers. In the cycle you enter the 

text via a text parameter, and of course you 

can choose whether the text should be in a 

straight line or along an arc. 

Thread milling cycles 262, 263, 264 and 

267 

In these thread milling cycles a separate 

feed rate is now available for tangential 

entry into the thread. Particularly with small 

thread sizes this makes it possible to select 

a higher subsequent cutting feed rate, 

which reduces production time. 

KinematicsOpt cycles 451 and 452 

(option) 

Fast optimization algorithms reduce the 

time for measurement, as does the fact 

that position optimization is now performed 

simultaneously with angle optimization. 

Furthermore, the ascertained offset errors 

are now available as result parameters, 

permitting subsequent program-controlled 

evaluation. 

Global Program Settings (GS) 

(option) 

Via an additional switch in the global 

program settings (GS) form you can now 

specify whether the values traversed in the 

virtual axis direction should be reset upon a 

tool change. 

8

File management: 

Support for ZIP archives 

In the iTNC 530’s file manager you can 

now create ZIP archives, in order to archive 

files of completed jobs, for example. Of 

course you can also open existing archives 

and extract files from there. 

Working with pallets 

Selected workpieces can be hidden during 

tool-oriented machining in combination 

with the pallet table. A new keyword is 

available for this. 

Optimizations to the DXF converter 

(option) 

Summary of the most important new 

features of the DXF converter: 

• Contours and machining positions can be 

selected faster and with better accuracy 

with a capture function. 

• During contour selection the iTNC shows 

the size of the smallest contained 

contour radius in the status bar. This 

smallest radius is also shown in a 

different color in the selected contour. 

That way you can tell immediately which 

tool can machine the contour in any 

case. 

• Preselected contours can now also be 

chosen in the tree view. 

Enhanced tool management 

(option) 

A particularly interesting function has been 

added to the enhanced tool management. 

There is now an import function for reading 

and exporting CSV files. CSV (commaseparated 

values) is a file format for the 

exchange of simply structured data. This 

function is especially useful for data 

exchange if you measure and calibrate your 

tools with external presetters. Excel can 

also open and save this file format. 

There is now also a simple possibility for 

deleting tool data quickly but carefully. The 

TNC shows the tool data to be deleted in a 

pop-up window, giving you the opportunity 

to make sure that no important data is 

deleted by accident.
