Introduction

With multi-axis machining, the main objectives are to achieve perfect surface quality, precision,
and speed without any need for remachining. Within this context, workflow is typically character-
ized by the CAD-CAM-CNC process chain. From the CAD system right through to the control
system, Siemens can offer an integrated solution for these requirements in the form of its SINU-
MERIK products.
SINUMERIK controls are equipped with powerful, advanced functions which, when intelligently
used, make the whole process of multi-axis programming and machining (particularly 5-axis
machining) considerably easier while at the same time improving the results of production.
This manual is a compact resource aimed at experts working in industrial and research environ-
ments who need to get acquainted with the key basic principles of multi-axis machining. Building
on this, it also provides machine users with practical tips so that they can organize their work effi-
ciently and provides programmers with an insight into the functions of the control and the CAD/
CAM system.
As regards the various application areas of multi-axis machining, the dedicated functions that
have been specifically developed for each area are briefly introduced and considered in context.
Although many of the aspects cannot be covered in depth by this manual, you will find additional
information in the appropriate Sinumerik documentation and relevant literature (See "Further
information/documentation" on page 108.)
This manual is designed to supplement the Tool and Mold Making (3 axes) manual, which deals
with the typical functions of 3-axis machining. Please refer to this original manual for more in-
depth information about the basic principles and functions involved.
