Legal information

Legal information

Warning notice system

This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.

DANGER

indicates that death or severe personal injury will result if proper precautions are not taken.

WARNING

indicates that death or severe personal injury may result if proper precautions are not taken.

CAUTION

with a safety alert symbol, indicates that minor personal injury can result if proper precautions are not taken.

CAUTION
without a safety alert symbol, indicates that property damage can result if proper precautions are not taken.

NOTICE
indicates that an unintended result or situation can occur if the corresponding information is not taken into

account.

If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.

Qualified Personnel

The product/system described in this documentation may be operated only by personnel qualified for the specific
task in accordance with the relevant documentation for the specific task, in particular its warning notices and
safety instructions. Qualified personnel are those who, based on their training and experience, are capable of

Preface

Structure of the documentation

The SINUMERIK documentation is organized in 3 parts:

● General documentation

● User documentation

● Manufacturer/service documentation

Information on the following topics is available at
http://www.siemens.com/motioncontrol/docu:

● Ordering documentation
Here you can find an up-to-date overview of publications.

● Downloading documentation
Links to more information for downloading files from Service & Support.

Target group

Benefits

● Researching documentation online
Information on DOConCD and direct access to the publications in DOConWEB.

● Compiling individual documentation on the basis of Siemens contents with the My
Documentation Manager (MDM), refer to http://www.siemens.com/mdm

My Documentation Manager provides you with a range of features for generating your
own machine documentation.

● Training and FAQs
Information on the range of training courses and FAQs (frequently asked questions) are
available via the page navigation.

This publication is intended for programmers, planning engineers, machine operators and
system operators.

With the Programming and Operating Manual, the target group can develop, write, test and
debug programs and software user interfaces.

In addition, it enables the target group to operate the hardware and software of a machine.

1.5 Coordinate systems

1.5 Coordinate systems

As a rule, a coordinate system is formed from three mutually perpendicular coordinate axes.
The positive directions of the coordinate axes are defined using the so-called "3-finger rule"
of the right hand. The coordinate system is related to the workpiece and programming takes
place independently of whether the tool or the workpiece is being traversed. When
programming, it is always assumed that the tool traverses relative to the coordinate system
of the workpiece, which is intended to be stationary.

1.5 Coordinate systems

Machine coordinate system (MCS)

The orientation of the coordinate system relative to the machine depends on the respective
machine type. It can be rotated in different positions.

The directions of the axes follow the "3-finger rule" of the right hand. Seen from in front of the
machine, the middle finger of the right hand points in the opposite direction to the infeed of
the main spindle.

Description

1.5 Coordinate systems

The origin of this coordinate system is the machine zero.
This point is only a reference point which is defined by the machine manufacturer. It does not
have to be approachable.

The traversing range of the machine axes can be in the negative range.

Workpiece coordinate system (WCS)

To describe the geometry of a workpiece in the workpiece program, a right-handed, right­angled coordinate system is also used.
The workpiece zero can be freely selected by the programmer in the Y axis. In the Z axis, it
lies in the turning center.

<

;

Figure 1-5 Workpiece Coordinate System

Relative coordinate system (REL)

In addition to the machine and workpiece coordinate systems, the control system provides a
relative coordinate system. This coordinate system is used for setting reference points that
can be freely selected and have no influence on the active workpiece coordinate system. All
axis movements are displayed relative to these reference points.

Note
The actual value in the associated coordinate system can be activated and displayed in the

"Position" operating area using the "MKS/WKS REL" vertical softkey.

1.5 Coordinate systems

Clamping the workpiece

For machining, the workpiece is clamped on the machine. The workpiece must be aligned
such that the axes of the workpiece coordinate system run in parallel with those of the
machine. Any resulting offset of the machine zero with reference to the workpiece zero is
determined along the Y axis and entered in a data area intended for the settable work offset.
In the NC program, this offset is activated during program execution, e.g. using a
programmed G54.
