I bought "CNC Programming Handbook" and found it useful. It does a credible job of explaining Fanuc tape code. It might be the best of its genre of CNC programming books but like most of its kind the only thing contemporary about it is its date of publication. Otherwise, it is a throw back to the late 1970's and early 1980's when CNC could get along with a dearth of explanations and explanations that were hardly rigorous. For example: 1) Mr. Smid brings forward a 50 year definition of Numerical Control that is just as useless today as it was in its time. 2) He doesn't define interpolation; the word does not even appear in the book's appendix. 3) There is no discussion of servo and associated topics like proportional negative feedback control and following error. 4) Mr. Smid keys his explanation of CNC Cartesian systems with reference to "Home" as if this word has meaning. Words like reference return and machine zero have meanings established by CNC configuration functions but the word "Home" has meaning only in context. Operators will call "Home" a variety of machine positions such as tool change positions and load stations. (Even in the assumed meaning of "Home" as synonymous with machine reference how would a programmer or operator clarify the "Home" position on an axis with distance coded scaled?) 5) The book does not dissociate machine reference (a landmark position) from the machine zero position (associated with the machine coordinate system which is the "ground" system of the coordinate system hierarchy). Even in the early 1980's Fanuc CNC had machine setup parameters to specify the reference return point as a point in the machine coordinate system. 6) The idea of a hierarchy of Cartesian systems (frames) is beyond the books comprehension.
