To the Learner
1 Introduction
1.1 To the Learner
This set of exercises offers the opportunity to establish your knowledge and capabilities gained with handling
the MTS CNC Simulator Turning & Milling as well as to extend and apply these.
As the proverb says, practice makes perfect! Provided that you are willing to learn, the book will support you
by its systematic structure. The exercises serve two purposes. Firstly, you find your introduction into further
studying the CNC technique easily according to your individual preliminary knowledge and independently on
the CNC software available. Secondly, you can make handling the MTS CNC Simulator with its varied fields
of application accessible for you or perfect it.
You will find out quickly how difficult it is to detect the „optimum“ solution of a problem. Unfortunately, there is
no royal road to learning! The best way of the single case does not only depend on the technical and
organizing environment and the workpart spectrum of the CNC manufacture but also on your personal
preference of one or the other working mode. Especially in this respect, the MTS system provides an efficient
and multiple program package. It does not oblige you to apply a certain programming method but offers all
access possibilities of up-dated CNC technique. With regard to this, our approaches are supposed to be
suggestions and the prepared final solutions do not represent complete and optimum solutions.
The set of exercises has been created for flexible application. The beginner should start with simple
exercises on turning or milling. Parts or whole exercises should not be skipped unless you feel firm and
repetitions are not required anymore.
Finally, enjoy working with these exercises and have soon success! We are grateful for any suggestions to
improve the book and hints on mistakes or lack of clarity which can never be completely excluded.

To the Learner
1 Introduction
1.1 To the Learner
This set of exercises offers the opportunity to establish your knowledge and capabilities gained with handling
the MTS CNC Simulator Turning & Milling as well as to extend and apply these.
As the proverb says, practice makes perfect! Provided that you are willing to learn, the book will support you
by its systematic structure. The exercises serve two purposes. Firstly, you find your introduction into further
studying the CNC technique easily according to your individual preliminary knowledge and independently on
the CNC software available. Secondly, you can make handling the MTS CNC Simulator with its varied fields
of application accessible for you or perfect it.
You will find out quickly how difficult it is to detect the „optimum“ solution of a problem. Unfortunately, there is
no royal road to learning! The best way of the single case does not only depend on the technical and
organizing environment and the workpart spectrum of the CNC manufacture but also on your personal
preference of one or the other working mode. Especially in this respect, the MTS system provides an efficient
and multiple program package. It does not oblige you to apply a certain programming method but offers all
access possibilities of up-dated CNC technique. With regard to this, our approaches are supposed to be
suggestions and the prepared final solutions do not represent complete and optimum solutions.
The set of exercises has been created for flexible application. The beginner should start with simple
exercises on turning or milling. Parts or whole exercises should not be skipped unless you feel firm and
repetitions are not required anymore.
Finally, enjoy working with these exercises and have soon success! We are grateful for any suggestions to
improve the book and hints on mistakes or lack of clarity which can never be completely excluded.

manufacturing process with the MTS CNC Simulator including following steps: define workpart zero, set up
the processing sequence, determine tools, fixtures and technological data; generate, set up, test and correct
the program at the CNC simulator. A bolt with an external diameter of ∅ 100 mm and the length of 107 mm is
to be clamped for the test.
Use the LAP function G85 and G87 in longitudinal mode.
