Self-aware and self-correcting machine tools for robust accuracy

许多财富都是通过为航空航天、汽车、石油和医疗行业加工复杂零件而创造的。制造更复杂零件的能力，以及更严格的公差，使原始设备制造商(OEM)能够设计出在性能和成本方面领先于国际竞争对手的产品。它还使零部件制造商能够向加拿大和国际原始设备制造商提供具有竞争力的产品。在这两种情况下，这类行业都是机床的用户，往往随处可见。用户的不同之处在于他们的选择能力，然后最大限度地利用他们已安装的制造基础。近年来，一个日益增长的趋势是，机床将车削和铣削等工序结合在一起，在一个设备中生产复杂的零件，从而潜在地提高生产率和质量。但它们高昂的资本成本意味着正常运行时间至关重要，制造超出容差的零件即使是第一个零件也是不可接受的。

Much wealth is created by machining complex parts for the aerospace, automotive, oil and medical industry to name a few. The ability to make ever more complex parts, with tighter tolerances, enables original equipment manufacturers (OEMs) to design products that stay ahead of international competitors in terms of performance and cost. It also enables part manufacturers to competitively supply Canadian and international OEMs. In both cases, such industries are users of machine tools often widely available. What differentiates users is their capacity to select and then get the most out of their installed manufacturing base. In recent years, a growing trend has been towards machines which combine processes such as turning and milling to produce complex parts in a single setup thus potentially increasing productivity and quality. But their high capital cost means that uptime is crucial and making an out-of-tolerance part is unacceptable even for the first part made.
