Advance control for centreless rectifying grinder - has vibration sensor acting when grinder contacts piece to terminate rapid advance

The piece (27) is rectified between a stationary grinder and a mobile grinder (2) with the latter advanced rapidly from withdrawn position to apply continuous pressure to the piece (27) during rectification. The mobile grinder (2) is advanced by a motor (7, 8), which receives power through a distributor (12), and the piece-mounting (25) incorporates a detector (24) of vibrations. When the piece (27) is contacted by the mobile grinder (2), and is pushed against the stationary grinder, the detector (24) is activated. At this instant the detector (24) sends a signal to an amplifier (23). The amplifier controls the feed to a relay (22) which in turn controls the power feed to the motor. The mobile grinder (2) may be mounted on a slide (4) which is displaced by the motor in the form of a hydraulic ram (7, 8).

Workpiece processing method, involves processing workpiece and tool directly or indirectly corresponding to compared value that is determined by comparing distance between proximity sensor and workpiece with desired value

The method involves positioning a workpiece and a rotating tool (3) i.e. rotating machined tool, by relative movement before interference of the tool that is rotated during distance measurement. Distance between a proximity sensor radially aligned to the tool and the workpiece is determined and compared with a desired value. The workpiece and/or the tool are directly or indirectly processed corresponding to a compared value. The proximity sensor is designed as an inductive or capacitive sensor and a magnetic or optical sensor. An independent claim is also included for a device for processing a workpiece.

Power machine control apparatus

When the mobile unit (5) of the machine, such as a press-platen, makes contact with fixed parts (for example by impact between the tool and the piece to be worked), there is an immediate slowing down of the mobile unit, even before, for example, the oil pressure of the hydraulic control system for the mobile unit increases, which is detected by a sensor (9, 10) constructed as an optical device providing a signal having a frequency proportional to speed. At a minimum threshold signal from the device a predetermined programme is initiated by a computer, or programmer, 7. The device may alternatively be used in a safety system. <IMAGE>

MACHINE TOOL GAP ELIMINATOR

There is disclosed a gap eliminator used for reducing air cut time in machine tools. To compensate for supply voltage variations a signal proportional to the power or current consumption of an electric motor under no or light load conditions is compared with the signal under load conditions after attenuation of the latter, to provide a signal by which the feed rate of the tool is controlled. A noise cancelling circuit for eliminating periodic noise is disposed between the detector producing the signal proportional to consumption and the comparator in order to eliminate periodic noise from the signal. Further an abnormal level of the noise-cancelled signal is detected to provide a secondary signal, by which the machine is brought to a stop.

ROBOTIC POLISHING OF PLANAR AND NON-PLANAR SURFACES

The surface of a workpiece is polished by passing a computer numerically controlled rotating flexible abrasive flap wheel across the surface of the workpiece, continuously measuring the diameter of the flap wheel which decreases due to wear of the ends of the flaps, and compensating for the decreasing diameter by a machine control computer which adjusts the distance of the flap wheel from the workpiece surface to maintain a flap wheel-workpiece interference which gives a known material removal rate. The method is applicable to non-planar, as well as planar surfaces, and is particularly well adapted to the polishing of the gas path surfaces of hollow fan blades used in gas turbine engines.

SERVOMECHANISM FEED SYSTEM

A servomechanism feed system providing delayed "triggered" backup in combination with an automatic velocity control. The system permits high velocity approach of a movable object, and retract and automatic damping of velocity for stable operation thereby relieving the operator from manual search for desired conditions. Approach means operates in response to an input signal and at low velocity stabilizes near desired conditions. Backup or retract signal is "transistor triggered" only after high velocity overshoot of the reference signal. At this time complementary transistors or other electronic control devices shunting the output become conductive to reduce the velocity and give stable operation.

VERFAHREN UND VORRICHTUNG ZUM STEUERN DER VORSCHUB- UND ZWISCHEN-RUECKLAUFBEWEGUNG DER SCHLEIFSCHEIBE EINER SCHLEIFMASCHINE

Prior to the finish-grinding in size-controlled grinding operations, workpieces and grinding machine are often relieved of pressure by briefly lifting the grinding wheel away from the workpiece. The grinding wheel is then fed once again at a very low rate which corresponds to the finish-grinding, as a result of which the machining time is substantially lengthened. In order to shorten this time, the invention proposes to carry out the renewed feed of the grinding wheel at a relatively high rate and only to change over to a low rate corresponding to the finish-grinding when the grinding wheel makes contact with the workpiece. The control device used for this purpose comprises a supplementary device to establish the point at which the grinding wheel makes contact with the workpiece, this emitting a corresponding signal to change over the rate of feed.

Drive system for multiple spindle machine tool

A drive system for a multiple spindle machine tool which includes a separate servo motor for powering the drum shaft which serves as the basic control element for the timing and movement of tools which are operable upon the workpieces carried in the spindles. The speed of the servo motor is regulated by a tachometer in a feedback loop to hold the speed of the motor at any chosen value. The drum shaft rotates at either high speed during tool traverse or low or feed speed during machining operations. A second tachometer driven by the spindle drive system generates a signal proportional to the spindle speed and that signal coordinates the low feed speed of the drum shaft with the spindle speed. Conventional clutches for high-speed and reverse operation of the drum shaft are replaced by switches and potentiometers.

Method for controlling and/or monitoring a workpiece machining process

The invention relates to a method for controlling and/or monitoring a workpiece machining process. In the workpiece machining process, a tool having a working surface is brought into contact with a surface of a workpiece to be machined. To do so, a feed movement is carried out, causing the tool to approach the workpiece. In the machining process, the tool and/or the workpiece rotate about a tool axis and/or workpiece axis. The feed movement is carried out while the tool and/or workpiece is rotating. While the feed movement is carried out, an auxiliary medium is introduced into a region between the working surface of the tool and the surface of the workpiece to be machined. During the feed movement, bending moments and/or forces acting transversely to the tool axis and/or transversely to the workpiece axis and/or torques occurring during the rotation of the tool about the tool axis and/or during the rotation of the workpiece about the workpiece axis are captured in a time-resolved manner. A status of the approach process is inferred from the values and/or time profiles of the captured bending moments, forces and/or torques.
