摘要： A grinding or polishing machine comprises a rigid platform on which a workhead spindle and a grinding wheel spindle are located. The grinding wheel spindle is mounted on a sub-assembly which is attached to the platform by means of flexures which permit limited movement of the sub-assembly in a direction generally parallel to the direction in which the wheel has to advance to achieve grinding or polishing of a workpiece mounted on the workhead spindle. The flexures generally inhibit movement of the sub-assembly in all other directions. Two grinding wheels are mounted on the platform, one on each of two sub-assemblies, and each sub-assembly is attached to the platform by flexures as aforesaid. The flexure mounting points are located generally centrally of the machine and are located on either side of and close to the machine centre line. In a grinding or polishing machine having workpiece spindle means, tool spindle means mounted on sub-assemblies which permit limited relative movement in one direction to effect tool and workpiece engagement cam drive means is provided whereby each sub-assembly is movable to advance or retract each tool spindle towards and away from the workhead spindle.

摘要： In a machine tool a reference straight-edge is mounted on the worktable of the machine tool and the position of the worktable and therefore the workpiece along the x-axis of the machine is determined by reference to the straight edge; a linear scale is mounted to move with the tool and a reading head associated therewith provides a measure of the position of the tool along the x-axis of the machine, and a linear scale is mounted to move with the worktable and a reading head associated therewith provides a measure of the position of the worktable and therefore the workpiece along the z-axis of the machine; wherein the linear scale mounted to the tool and the reference straight edge mounted to the worktable and the reading heads and sensors associated therewith are all mounted in the same plane, and the machine is mounted so that the said plane is horizontal. The linear tool scale is aligned with the tool axis which intersects the point of application of the tool to the workpiece. The reference straight edge sensor is also located on the same axis so as to be on the same straight line as the linear tool scale and the point of application of the tool to the workpiece. The reading head for the linear scale mounted to the worktable is also located in the same vertical plane containing the said tool axis. Where the tool is a grinding wheel, the wheel is mounted with its axis of rotation at the same height as the reference straight edge and the linear scale associated with the wheel.

摘要： A method is described for grinding a composite workpiece (18) to form a component having concentric (31) and eccentric cylindrical regions (30). The method comprises mounting the workpiece (18) in a computer controlled grinding machine (10) having a grinding wheel (12) the advance and withdrawal of which is controllable by a programme entered into the controlling computer (32), loading a wheelfeed controlling programme into the computer, relatively positioning the grinding wheel and the workpiece to align the wheel with a first selected region of the workpiece, advancing the grinding wheel towards the selected region so as to grind the surface thereof, controlling the wheelfeed so as to maintain grinding contact between the grinding wheel and the workpiece so as either to grind a concentric cylindrical region thereon or an eccentric (offset) cylindrical region thereon as required, information about each selected region of the workpiece being stored in the computer and addressed as appropriate so that the wheelfeed can be cotrolled appropriately depending on whether a selected workpiece region is to be ground as a concentric or an eccentric (offset) cylindrical region. The method allows a workpiece having both concentric and eccentric (offset) cylindrical regions thereon to be ground using a single grinding machine under computer control without demounting the workpiece from the machine. The method also envisages introducing small advance and retract movements in the wheelfeed whilst the grinding wheel is engaged in grinding a concentric cylindrical workpiece region so as to introduce into the ground region an eccentricity which is equal and opposite to any eccentricity which grinding process forces introduce into the ground region, so that the two eccentricities cancel out. A computer controlled grinding machine is described as are programmes for controlling the machine.

摘要： A machine tool has a carriage (28), has a workpiece carriage (28) for carrying a workpiece (32) from which material is removed by a tool (54) carried by a tool carriage (48). A two-axis scale (86, 88) is attached to one of the carriages, and cooperates with a reading head (96, 98) attached to the other carriage. The output from the reading head is processed by signalling processing means to provide an indication of the position and/or movement of the carriages relative to each other and for generating positional data about one or both of the carriages to assist in controlling their movement in order to perform a machine operation. By directly measuring the relative positions of the two carriages, problems arising from, for example, distortions of the machine frame on which the carriages are mounted are at least mitigated. A preferred embodiment of the machine incorporates a second reading head attached to one carriage and incorporating the scale on another carriage so that the outputs from the two reading heads can be used to determine whether there has been any relative angular displacement of the paths followed by the carriages. There is also provided a method of determining the linear movement of one of the carriages relative to the other, and the machining process achieved using the machine tool.

摘要： A method of accoupling a driven member (50) from a driving member (46) used to rotate the driven member is disclosed. The method comprises the step of connecting the driving member to the driven member via a connecting means (38) which is torsionally rigid in a plane generally perpendicular to the axis of rotation of the driven member (50), but is readily deformable in other planes to accommodate misalignment. A drive decoupling means for achieving the method is also provided, wherein the connecting means comprises a laminated device attached to the driving member via at least one off axis connection and to the driven member by at least one other off axis connection, the connections being circularly spaced one from the other. Two such decoupling means may be connected in series to compensate for both offset and misalignment. The method and decoupling means are of particular use in machine tools, such as lathes and grinding machines for transmitting drive to workpieces therein.

摘要： The time to grind a workpiece can be reduced by selecting a grinding wheel whose width is not substantially greater than wheel strength considerations require, and which may therefore be less than the axial length of the region to be ground providing a work rest or work steady to increase the workpiece stiffness if required, and performing a succession of plunge grinding steps so as to grind the whole of the said axial region. Typically the grinding wheel is an electroplated CBN wheel, and the width of the grinding wheel selected is the narrowest permissible given the desired feed rate and motive power available. A grinding machine is disclosed comprising a wheelhead having mounted thereon a grinding wheel whose width is not substantially greater than that dictated by structural and strength requirements, programmable indexing means to enable the relative positions of the wheelhead and workpiece to be adjusted in a sequence of steps to achieve a sequence of plunge grinds, which may or may not overlap, to enable a region of the workpiece to be ground, the axial extent of which is greater than the width of the wheel, and wheel feed means and control means by which the feed rate is controlled, whereby the wheel feed rate is similarly programmable to enable a feed rate to be achieved which is limited only by the peak and RMS power capabilities of the wheel spindle drive motor, so that the rate of material removal is as high as is compatible with the power capabilities of the machine during each plunge, thereby optimising the total cycle time for grinding.
摘要翻译：可以通过选择其宽度基本上不大于所考虑的车轮强度的砂轮来减少研磨工件的时间，并且因此可能小于待研磨区域的轴向长度以提供工作休息或稳定地工作如果需要，增加工件刚度，并执行一连串的切入步骤，以磨削整个所述轴向区域。通常，砂轮是电镀CBN轮，并且所选砂轮的宽度在给定所需的进给速率和动力的情况下是最窄的。公开了一种研磨机，其包括：砂轮头，其上安装有砂轮，其宽度基本上不大于由结构和强度要求所规定的砂轮;可编程分度装置，以使得能够以一系列步骤调整砂轮头和工件的相对位置以实现可能重叠或可能不重叠的一系列插入式研磨，以使得能够研磨工件的区域，其轴向范围大于车轮的宽度，以及车轮进给装置和控制装置，进给速度被控制，由此车轮进给速率可类似地可编程，以使得能够实现仅由车轮主轴驱动电动机的峰值和RMS功率能力限制的进给速率，使得材料去除速率高达在每次插入期间与机器的功率能力兼容，从而优化了磨削的总循环时间。
