Problems incurred during gear manufacture can be frustrating and often a time consuming experience. Transmission error and gear noise are a fact of life for some, but Why? Today, we have the most advanced CNC Gear Metrology machines available, capable of measuring gears to very exacting standards. These machines present us with a sophisticated array of colourful graphs and endless streams of data, all indicating that we have a good gear OR a Lead Error OR a Profile Error OR, AND, ALSO, etc. etc. This is fine, but as yet these machines do not tell us which operation, process, tool, nut, bolt or washer is responsible for the errors they find. This we have to interpret ourselves. Scenario: A component is submitted for one of its scheduled inspections; the gear inspector puts it through the inspection machine and is presented with graphs and data that have areas of RED! "Sorry it's failed" remarks the inspector "What's wrong with it?" enquires the machine setter "Probably the cutter", the inspector replies The machine setter changes the cutter, the old one sent for regrind (probably unnecessarily) and the whole procedure is repeated. More RED graphs, another vague suggestion, another cutter change, etc, etc. Sound familiar? There are many companies whose gear inspectors have been responsible for this kind of service. Without the ability to interpret the information given by these machines: ~ YOU HAVE THE MOST EXPENSIVE GO - NOGO GAUGE IN THE WORLD! It is to help with this situation that this manual has been produced. By explaining the graphs and indicating the causes, it enables you to get to the Root Cause of the problem thus saving you time and money by reducing unnecessary DOWN TIME. |
