    摘要: A workpiece rotational speed controller having a pulse counter responsive to a pulse signal generated from a pulse generator for indicating the actual angular position of a cam shaft during grinding on a cam grinding machine and a comparator for comparing a count value of the counter with any one of set values which are set in a plurality of digital switches to designate respective speed change positions. A region detection counter is further provided, which counts any coincidence signal from the comparator so as to enable a command voltage generator to apply to a servomotor for cam shaft drive a command voltage that changes step by step in correspondence to the region detection counter output. This counter output is also applied to a gate circuit, which is thus enabled to selectively apply the set values of the digital switches to the comparator.

    摘要: A grinding machine, having a wheel carrier with a rotatable cubic boron nitride grinding wheel mounted on a bed. The wheel carrier is slidable with respect to a work support device and a truing device, which are selectively opposed to the grinding wheel through movement of a traverse table. Feed and feed control devices are provided to feed the wheel carrier from a transient original position to an advanced position in a grinding operation. A detecting device is further provided to detect an absolute original position of the wheel carrier. The feed control device is arranged such that, whenever a truing instruction is supplied, the wheel carrier is retracted to the absoluted original position and then, is advanced therefrom to a truing position incremented by a predetermined truing infeed amount from the advanced position.

    摘要: A numerical control apparatus for machining non-circular workpieces such as a cam and the like has been disclosed. The cam and the like are used in changing the operation from rotational to linear motion. In designing the shape of the cam and the like, lift data prescribing the relationship between the rotational and linear motions is used. The lift data is given by the position sequence on the linear motion corresponding to a number of discrete rotational angles. Also, the tolerance of the positions is given from a functional aspect. The lift data is converted into profile data prescribing the shape of the cam and the like after being smoothed within the tolerance by a regression analysis, and machining of the non-circular workpieces is effected according to the profile data.

    摘要: A numerically controlled internal grinding machine for grinding a workpiece by a rough grinding operation with a rough grinding wheel and a finish grinding operation with a finish grinding wheel. The grinding machine detects the load power of a motor which drives the finish grinding wheel in order to determine a compensation value to enable subsequent compensation due to wear of the rough grinding wheel. In the successive rough grinding operation, the relative position of the workpiece is compensated for according to the determined compensation value, so that the diameter of the workpiece after the rough grinding operation is maintained at a desired constant value regardless of the wear of the rough grinding wheel.

    摘要: A truing apparatus includes a truing tool supported on a tool support movable radially and axially of a grinding wheel having a rounded corner and drivable by a feed drive unit coupled to the tool support to move along a predetermined path for truing the rounded corner of the grinding wheel. At least one contact member for contacting outer peripheral and end surfaces of the grinding wheel is mounted on the tool support, and a sensor is also mounted on the tool support for detecting a contact between the contact member and the grinding wheel. A feed control system controls the feed drive unit for moving the truing tool along the predetermined path. The feed control system controls the feed drive unit so that the contact member will move radially and axially of the grinding wheel until the sensor is actuated immediately after one truing process and immediately before a next truing process. A grinding wheel position detector detects radial and axial positions of the grinding wheel when the sensor is actuated immediately after the one truing process and immediately before the next truing process. A correcting unit corrects the predetermined path along which the truing tool is to move in the next truing process based on the positions of the grinding wheel detected by the grinding wheel position detector immediately after the one truing process and immediately before the next truing process.

    摘要: An apparatus for truing a grinding wheel includes a stylus movable in response to movement of a truer in synchronism therewith, and a template disposed in confronting relation to the stylus with a gap left therebetween. The truer is controlled in its motion by servomotors driven in response to a command issued from a numerical control unit. When the truer is caused by the numerical control unit to move out of control for some reasons, the stylus is brought into engagement with the template, thereby protecting the truer and a grinding wheel being trued thereby against damage which would otherwise result from such uncontrolled movement of the truer. When the truer is to be advanced for truing infeed against the grinding wheel, the stylus is disconnected by a clutch device from the truer, and only the truer is moved in the forward direction while maintaining a proper gap between the stylus and the template.

    摘要: Wear on the dressing tool is derived from an amount of movement that a grinding wheel is advanced until issuance of a signal from a sizing device for correcting data on the radius of the grinding wheel. The data on the radius of the grinding wheel is thus indicative of an actual radius of the grinding wheel regardless of a variation in the grinding wheel radius due to the wear of a dressing tool. Accordingly, the grinding surface of the grinding wheel can be exactly positioned at a grinding start position after the grinding wheel has been returned to its original position upon power supply failure, emergency machine shutdown or the like, so that any unwanted interference between the grinding wheel and a workpiece can be avoided.
