摘要： A method is described for setting up a computer controlled grinding machine for cylindricaly grinding concentric workpiece regions, in which a programme containing data about the workpiece and a programme containing wheelfeed instructions are loaded and the wheelfeed instructions programme is run so as to grind at least one such workpiece region to final form. The region is gauged and the magnitude and angular position of any unwanted eccentricity introduced by the grinding process, is noted, and the wheelfeed programme instructions or control derived therefrom signals are adjusted so that during subsequent grinding of the said region (or a similar region of a similar workpiece), the wheelfeed is controlled so as to compensate for said measured unwanted eccentricity. The workpiece region is stress relieved before the gauging. After setting up, the grinding machine will eccentrically grind a workpiece region which is to have a cylindrical surface concentric relative to the workpiece primary axis, rather than concentrically grinding the said region, the degree of eccentricity being such that when the cylindrically ground workpiece is stress relieved after grinding, the region will be concentric relative to the workpiece axis. A computer controlled grinding machine is described as are programmes for setting up and grinding.

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 controlled 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 grinding machine, particularly for grinding the crankpins (12) of a crankshaft, comprising a CBN grinding wheel (10) and a coolant nozzle (14) supplying a jet of coolant into the region being ground. During the final stage of grinding, when the slow feed of the wheel ceases and the dwell point is reached, a selector valve (18) is operated which reduces the coolant flow. This in turn reduces the lateral force on the crankpin and improves the roundness accuracy of the ground crankpin.
