The recent trend of machining technology in the field of automotive engines can be divided into the following four categories. Flexibility: To accommodate the proliferation of engines themselves, flexibility is required of the machining technology. In response to this need, some new technologies have been realized. Some examples are flexible transfer machines with the capability of machining more than ten kinds of cylinder blocks, automatic tooling change, and adoption of NC machine tools in the production line. Higher quality: The trend of the longer life cycle of automobiles has increased the need for higher quality. To realize higher quality of products, automatic tool compensation has become popular not only for grinding, but also for turning, boring and milling. Moreover in-line gaging or checking items are increasing. Higher efficiency: The main progress in this category is as follows: Reduction in machining cycle time by the more rigid structure of the machine tool itself, the application of mechanical feed mechanisms as well as mechanical transfer mechanisms, and improvement in operating efficiency by the development of new tool change mechanisms as well as mechanical transfer mechanisms, and improvement in operating efficiency by the development of new tool change mechanisms and longer tool life due to new tool materials. Conservation of energy and resources: Through the integrated effects of many small measures, for example, use of water soluble cutting coolant instead of cutting oil, conversion from wet to dry cutting, selection of appropriate, not excessive, motor capacity and improvement of the machine tool control sequence, desired results have been achieved to some extent.
