iTNC 530 New Functions with NC Software 340 49x-07

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 plain-

language 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 user-

friendliness 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 with NC Software 340 49x-07
—The iTNC 530 Makes Working with the Machine Even Easier

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.

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.

The Future is Now
—Graphic Selection of Contours and Contour Sections (Option)

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.

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.

—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).

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.

Stud cycles 256/257
Additional input parameters have been

added to the cycles for circular and

rectangular studs so that the radius and

angle for approach and departure can be

specified. This makes it easier to define the

approach and departure behavior when

space is limited.

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.

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 (comma-

separated 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.
