In preparing this series of lessons for students of Western lands, I have been compelled to proceed along lines exactly opposite to those which I would have chosen had these lessons been for students in India. This because of the diametrically opposite mental attitudes of the students of these two several lands. The student in India expects the teacher to state positively the principles involved, and the methods whereby these principles may be manifested, together with frequent illustrations (generally in the nature of fables or parables), serving to link the new knowledge to some already known thing. The Hindu student never expects or demands anything in the nature of "proof" of the teachers statements of principle or method; in fact, he would regard it as an insult to the teacher to ask for the same. Consequently, he does not look for, or ask, specific instances or illustrations in the nature of scientific evidence or proof of the principles taught. He may ask for more information, but solely for the purpose of bringing out some point which he has not grasped; but he avoids as a pestilence any question seeming to indicate argument, doubt of what is being taught him, or of the nature of a demand for proof or evidence. The Western student, on the other hand, is accustomed to maintaining the skeptical attitude of mind-the scientific attitude of doubt and demand for proof-and the teacher so understands it. Both are accustomed to illustrations bringing out the principles involved, but these illustrations must not be fanciful or figurative- they must be actual cases, well authenticated and vouched for as evidence. In short, the Western teacher is expected to actually "prove" to his students his principles and methods, before he may expect them to be accepted. This, of course, not from any real doubt or suspicion of the veracity or ability of the teacher, but merely because the Western mind expects to question, and be questioned, in this way in the process of teaching and learning.

Diese Publikation befa~t sich mit der Entwicklung einer Steuerung f}r die Freiformfl{chenbearbeitung mit der M|glichkeit, Bahnvorgaben in Parameterkoodinaten der Fl{chenbeschreibung zu interpolieren. Die damit verbundenen Vorteile sind der durchg{ngige Informationsflu~ f}r Geometriedaten, die Reduktion der NC-Datenmenge, die Flexibilit{t des Fr{sereinsatzes und die hohe Bearbeitungsgeschwindigkeit. Es wurde eine erweiterte NC-Programmierschnittstelle nach DIN 66025 zur Freiformfl{chenbearbeitung spezifiziert. Wesentlich dabei ist die Definitionvon beliebigen Fl{chenkurven als Fr{sbahn. Durch Verwendung der B-Spline-Kurvenapproximation werden alle in konventionellen Steuerungen vorkommenden Bahnen in einer einheitlichen Polynomform f}r die Sollwerterzeugung dargestellt. Ein darauf basierendes Einschrittverfahren zur allgemeinen Polynominterpolation wurde entwickelt. Die neuen Interpolationsverfahren und -strukturen f}r die Freiformfl{chenbearbeitung zeigen, da~ nur durch Spline-Generierung sowohl f}r die Bahn als auch f}r die Orientierung eine hohe Bahngenauigkeit zu gew{hrleisten ist. Aus den gewonnenen Ergebnissen wurde die Struktur einer fl{chenorientierten Steuerdatenaufbereitung in der Steuerung festgelegt.
