Numerous industries such as automotive, aerospace and implants and prosthesis require the manufacture of complex and precise parts. Some of those parts are machined directly while others are cast, forged or stamped with precise dies and molds that have been machined. Machining is a process requiring the motion of a cutting tool through a workpiece. The dimensional and geometric quality of the result depends largely on the ability of the machine to move its tool accurately. The inevitable errors in the construction and assembly of the machine and its usage will affect the machine accuracy so that it is necessary to periodically verify the machine status and take corrective actions to ensure product quality.

汽车、航空航天、植入物和假体等众多行业都需要制造复杂而精密的零件。 其中一些零件是直接机加工的，而另一些零件则是用机加工的精密模具铸造、锻造或冲压的。 机械加工是一种需要刀具在工件上运动的过程。 结果的尺寸和几何质量在很大程度上取决于机床精确移动刀具的能力。 机器的构造和装配及其使用过程中不可避免的错误会影响机器的精度，因此有必要定期验证机器状态并采取纠正措施以确保产品质量。
