I've had the following enquiry, and would appreciate comments from anyone more knowledgable in this sphere than myself! (In the meantime, I'll try to understand his problem better.)
Chris >We have experienced a great deal of system crashes and a high degree of >inaccuracies associated with all CNC software. We decided to involve >Topology and Automata experts to assist us in overcoming the problems. The >outcome was that the software data sets during the conversion from Hex to >Deci (ADI system) were the prime cause in that rounding off became >impossible for math coprocessors to handle at 1st level maths. For accurate >CNC operations we would require 4th level maths. It was later brought to our >attention that Microsoft was aware of this problem during the 1992 Alpha >Tests at which time it became abundantly clear that the problem could not be >rectified, furthermore the problem worsened as the time element entered the >equations, and as the frequency of 12 and 24 increased. Microsoft knew at >that time the metric system of measurement had to go and that Hex and Deci >will never mix. We are convince that engineering data exchange under ISO >10303 will be problematic and will emanate from the extensive use of real >numbers that are associated with the metric system of measurement. >Kindest regards, > >C H.
