摘要： The present invention provides for a readily exchangeable flex tool for machining a workpiece. The flex tool includes a driver and an tool carrying body. The driver is coupled to the tool carrying body in a manner which allows the tool carrying body to have at least two degrees of freedom with respect to the driver. The tool carrying body includes an elongate pilot shaft, the elongate pilot shaft and tool carrying body having a longitudinal axis. The at least two rotational degrees of freedom allowing the longitudinal axis of the tool carrying body and elongate pilot shaft to be aligned with a longitudinal axis of a reference bore contained in the workpiece and slidably inserted therein.

摘要： An automatic control system for machine tools having rotary tools is disclosed in which the tool drive motor load current, which is proportional to the mechanical load on said drive motor, is maintained at a selectable desired level by controlling the duration and phase of the power supplied to an alternating current feed motor which controls the distance between the rotary tool and the workpiece. A sensed load signal which is greater than the preselected level will cause the feed motor to move the tool away from the workpiece, while a load signal less than that desired will cause the feed motor to move the tool toward the workpiece.
摘要翻译：公开了一种具有旋转工具的机床的自动控制系统，其中与所述驱动电动机上的机械负载成比例的工具驱动电动机负载电流通过控制所提供的电力的持续时间和相位而被保持在可选择的期望水平连接到控制旋转工具和工件之间的距离的交流供电电动机。感测到的负载信号大于预选电平将导致进给电机将工具从工件移开，而小于所需的负载信号将导致进给电机将工具移向工件。
