    • A mass flow controller (10) comprises a fluid inlet (15) and at least one first flow meter (11) to measure a first flow rate ( F 1 ) and to output a first flow signal ( F S 1 ); at least one second flow meter (12) to measure a second flow ( F 2 ) rate and to output a second flow signal ( F S 2 ); a control device (13) connected to said first and second flow meters (11,12) and configured and arranged to generate a control signal ( C ); and at least one control valve (14) connected to said control device (13) to control a total flow rate ( F out ) through the mass flow controller (10) in response to the control signal ( C ). The control signal ( C ) is generated as a function of both the first and second flow signals ( F S 1 ,F S 2 ) such that the mass flow controller's (10) sensitivity to perturbations of said inlet pressure is minimized.
    • 质量流量控制器(10)包括流体入口(15)和至少一个第一流量计(11),用于测量第一流量(F 1)并输出第一流量信号(F S1); 至少一个第二流量计(12),用于测量第二流量(F 2)速率并输出第二流量信号(F S2); 连接到所述第一和第二流量计(11,12)并被配置和布置成产生控制信号(C)的控制装置(13); 以及连接到所述控制装置(13)的至少一个控制阀(14),以响应于控制信号(C)控制通过质量流量控制器(10)的总流量(F out)。 作为第一和第二流量信号(F S1,F S 2)的函数产生控制信号(C),使得质量流量控制器(10)对所述入口压力的扰动的灵敏度最小化。

    • The speed of rotation of a side wall roughing tool (250) can be varied in accordance with the speed of relative movement between the tool (250) and side wall portions of the shoe being roughed (the traverse speed of the tool). To this end, a flow control arrangement (F) is provided including a plurality of flow control valves (CV1, CV2), the arrangement being such that, with the rate of flow through each such valve set, the operator can select one or other to be switched into the hydraulic circuit by which a hydraulic motor (232) is driven, said motor effecting rotation of the tool. The selection of one or other flow control valve (CV1, CV2) is made by the operator during the digitising of the path of the tool relative to the shoe and such information is stored together with the programmed instruction, in the form of digitised coordinate axis values, for said path.
    • 侧壁粗加工工具(250)的旋转速度可以根据工具(250)和被粗糙的鞋的侧壁部分(工具的横动速度)之间的相对运动的速度而变化。 为此,提供了包括多个流量控制阀(CV1,CV2)的流量控制装置(F),该配置使得通过每个这样的阀组的流量,操作者可以选择一个或其它 被切换到驱动液压马达(232)的液压回路中,所述马达实现工具的旋转。 一个或另一个流量控制阀(CV1,CV2)的选择由操作者在刀具相对于鞋的路径数字化过程中进行,并且这些信息与编程指令一起以数字坐标轴的形式存储 值,用于所述路径。
