摘要： A machine tool, such as an orbital grinding machine, and method of operation thereof are disclosed whereby a metrology surface (60) formed on a component (50) of the machine tool is rigidly fixed relative to one of a workpiece support (10,12) and a tool support(22,32), such that the metrology surface (60) can be probed using a position probe (34) rigidly fixed relative to the other of the workpiece support and the tool support. The positions of the workpiece and tool supports at which the position probe contacts the metrology surface may be used to calculate a measure relating to the height between reference points or axes of the workpiece support and tool support (such as a tool infeed arrangement). This height measure may be used by a controller of the machine to improve the accuracy of its control of the location of the tool relative to the workpiece.

摘要： A method of machining a workpiece using a machine tool, the machine tool comprising a tool mount carrying a tool, a workpiece mount carrying a workpiece, a drive mechanism for moving at least one of the tool mount and the workpiece mount relative to the other, and a control arrangement for controlling the drive mechanism. The method comprises moving at least one of the tool mount and the workpiece mount with the drive mechanism under the control of the control arrangement so that the tool contacts a portion of the workpiece to commence a machining operation, and the tool then removes material from the portion of the workpiece until completion of the machining operation, the movement being such that the relative velocity between the tool and the workpiece decreases continuously during the majority of the time that the tool and the workpiece are in contact with each other during the machining operation.
摘要翻译：一种使用机床加工工件的方法，所述机床包括承载工具的工具架，承载工件的工件安装件，用于相对于另一工具移动所述工具安装件和所述工件安装件中的至少一个的驱动机构，以及用于控制驱动机构的控制装置。该方法包括在控制装置的控制下用驱动机构移动工具架和工件安装件中的至少一个，使得工具接触工件的一部分以开始加工操作，然后工具将材料从工件直到完成加工操作为止，运动使得在加工操作期间刀具和工件彼此接触的大部分时间内，刀具和工件之间的相对速度连续减小。
