    • A method is described for setting up a computer controlled grinding machine for cylindrically 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 regions 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 whellfeed programme isntructions 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.

    • Working factors which influence a bending angle are specified from data sent from an NC device (10) in a grouping factor specifying section (13), and a tolerance at the time of grouping is set for the specified factors in a tolerance setting section (14), whereby grouping of corners to be bent is performed in a corner grouping section (15). Compensating conditions are then set in a compensating condition setting section (16), and compensating data for a depth amount is calculated based on actual depth data of a corner bending performed on a good product in a compensating data calculating section (17) based on the compensating conditions so set, and process data of the bending process is changed in a process data changing section (18). Thus, the depth amount of a corner to be bent is compensated whose bending angle measurement is not performed based on a compensating value for a depth amount of a specific corner to be bent for which a bending angle has actually been measured.
    • 影响弯曲角度的工作因素由分组因子确定部(13)中从NC装置(10)发送的数据来指定,并且在公差设定部(14)中为规定的因素设定分组时的公差 ),由此在拐角分组部(15)中进行要弯曲的角的分组。 然后在补偿条件设定部(16)中设定补偿条件,基于补偿数据计算部(17)中对好产品进行的拐角弯曲的实际深度数据,基于 补偿条件如此设定,并且在过程数据改变部分(18)中改变弯曲过程的处理数据。 因此,基于实际测量弯曲角度的要弯曲的特定拐角的深度量的补偿值,补偿不进行弯曲角度测量的弯曲角度的深度量。

    • In bending a work, a temporary drive-in position of a ram is calculated from working conditions that are inputted from a working condition input section and information on the relationship of a spring back angle relative to a target bending angle of a work stored in a spring back data section, and the ram is driven to this temporary drive-in position, where a bending angle of a work is detected by means of an angle measuring unit. Following this, a final drive-in position of the ram is obtained from the bending angle so detected, relation ship of a ram drive-in amount relative to the work bending angle stored in a bending angle/drive-in amount data section and relationship of the spring back angle relative to the target work bending angle stored in the spring back data section, and then the ram is driven to a final drive-in position so obtained to thereby complete the bending process.
