GRINDING MACHINES Grinding is the process of removing metal by the application of abrasives which are bonded to form a rotating wheel. When the moving abrasive particles contact the workpiece‚ they act as tiny cutting tools‚ each particle cutting a tiny chip from the workpiece. It is a common error to believe that grinding abrasive wheels remove material by a rubbing action; actually‚ the process is as much a cutting action as drilling‚ milling‚ and lathe turning. The grinding machine supports and

Generalization is the ability of a machine learning algorithm to perform accurately on new‚ unseen examples after training on a finite data set. The core objective of a learner is to generalize from its experience.[2] The training examples from its experience come from some generally unknown probability distribution and the learner has to extract from them something more general‚ something about that distribution‚ that allows it to produce useful answers in new cases. Machine learning‚ knowledge discovery

Let me start off this essay by saying that I believe H.G.(Herbert George) Wells is one of the most intelligent writers of his time: a true futurist. Obviously‚ I read The Time Machine by H.G. Wells and I would like to say that it was extremely well written and sounds as though it was written fairly recently. It may just sound this way because the human race has not really tried Time Traveling. The theme of The Time Traveler is‚ as I see it: Think about what you are doing before doing it. The Time

Lathe Machine Turning is one of the most common of metal cutting operations. In turning‚ a workpiece is rotated about its axis as single-point cutting tools are fed into it‚ shearing away unwanted material and creating the desired part. Turning can occur on both external and internal surfaces to produce an axially-symmetrical contoured part. Parts ranging from pocket watch components to large diameter marine propeller shafts can be turned on a lathe. The capacity of a lathe is expressed
