许多制造商，特别是机床制造商，致力于服务创新，以提高其市场竞争力。机床贸易公司希望通过从销售产品（即机床）转向销售产品和服务的综合组合（所谓的产品服务系统（PSS））来创造增值过程，从而与其他发展中公司竞争。这就是服务化的过程。本研究的目的是探讨服务化机床工业的好处，并确定这种方法对工程公司绩效的影响。同样重要的是，作为预测性维护的一部分，评估部件的精度，以支持机床的服务化。本文提出了一个滚珠丝杠副性能评价的案例研究。基于声发射传感器和机器学习技术的数据，监测5轴龙门机床中两个平行滚珠丝杠的退化。这项工作的意义在于，作为机床精度一部分的滚珠丝杠性能对于高价值制造至关重要。机床用户更希望他们的机器能够通过机器贸易商提供的预测性维护服务保修来维护所需的公差，并使他们的机器保持最新状态，以减少不必要的停机时间。
Many manufacturers, in particular machine tool builders, aim for service innovation in order to improve their market competitiveness. Machine tool trading companies expect to create a value-added process through shifting from just selling product i.e. machine tools to selling an integrated combination of product and services, so called product-service system (PSS) which in turn competes with other developing companies. This is the process of servitization. The purpose of this work is to explore the benefits of servitizing machine tool industry and identify the effect of such an approach on the performance of engineering companies. As important, is to evaluate the accuracy of components as part of predictive maintenance, to support machine tool sevitization. This paper proposed a case study of ballscrew performance assessment. The purpose was monitoring the degradation of two parallel ball screws in a 5-Axis gantry machine tool, based on data from an acoustic emission sensor and machine learning technology. The significance of this work is that ballscrew performance as part of machine tool accuracy is critical for high value manufacturing. Machine tool users would prefer their machines to be maintained to the required tolerance by the predictive maintenance service warranty offered by the machine trader and keep their machines up to date to reduce unnecessary downtime.
