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.
