Title: Improvements in or relating to machine tool control systems
Inventor: SHILLAM NORMAN FREDERICK
IPC: B23Q15/12
Filed: 1969-05-12
Abstract: 1293760 Machine tool control systems NATIONAL RESEARCH DEVELOPMENT CORP 12 May 1970 [12 May 1969] 23998/69 Heading G3R A servo-control system for a machine tool (e.g. a lathe), using the thermo-electric voltage V TW  developed between a cutting tool and a workpiece to control cutting speed, is generally as described in Specification 1293759 but the claims are directed primarily to the arrangement for detecting the accumulation of swarf between a workpiece and the machine frame. Due to the thermo-electric e. m.f. V TW  generated, a thermo-electric current flows from the thermo-electric junction between workpiece 21 and cutting tool 23, through an insulated toolholder 22, R26, the machine frame (indicated as earth point), R25, brush 20, slip ring 18, spindle 17, chuck 19, and into workpiece 21 completing the circuit. Swarf which simultaneously touches the workpiece and frame, substantially short circuits R25 causing an increase in thermoelectric current and consequently an increase in voltage V T  H  across R26. In addition an input voltage V SR  to an amplifier 10 substantially disappears, V TH  increasing correspondingly so that the sum V SR  + V TH  = V TW  does not change and amplifier 10 output is unaffected. A swarf threshold circuit 27 compares V TH  with a reference level from a pot 28 and when V TH  is excessive operates a switch circuit 30 which lights a lamp 32 to attract the lathe operator. At the same time an override signal is sent to a threshold 4 which causes the opening of a switch 2 and closing of a switch 15. Thereby the lathe spindle speed is reduced to a low steady value, being governed by the setting of a potentiometer 16 instead of a potentiometer 1. A peak charge circuit (including a capacitor and diode not shown) has an output which is an average of peak excursions of the signal in the outer feedback loop, and allows rapid decrease in cutting speed providing additional compensation for attenuations of the outer loop control signal caused by swarf.

Apparatus for the controlled recovery of converter gases comprises a hood 3 having a downwardly depending skirt 4 attached thereto by a flexible apron 6 which overhangs the converter nose 2 by about 1 metre and does not form a fluid-tight seal therewith, the ratio of the skirt bottom diameter to that of the converter nose being in the range 1À5 to 2À5. A series of pressure measuring points 10 in a calm zone within the top of the skirt cooperates with an external measuring point in the same plane to activate a damper 12 via a draught regulator 11 to keep the pressure difference inside and outside the hood constant, the damper being prevented from closing completely by stops 15, 16 which act in the limit position to cut out the regulator automatically. The damper is situated downstream of a dust extractor 14 and upstream of a chimney (13) Fig. 3 (not shown). A fan in the chimney opens the damper when blast commences. At the blowing through stage, the damper closes and a reduced inspired gas flow in the hood ensues, at the end of blowing-through, collection of the converter gases without combustion is obtained. At the end of the refining period, the exhaust gas flow is reduced and the damper is closed until the end of the blast, when it opens to blow-through the installation. In order to tilt the converter, the skirt is raised by any known means, the flexible apron bending back on itself to facilitate this.
