Abstract

1,190,072. Testing materials. R.A. BILLETT. May 28, 1968 [March 6, 1967], No. 10394/67. Heading G1S. [Also in Division G3] In an apparatus to control the temperature of a tool on a machine the E. M. F. generated at the interface between the cutting tool and the workpiece, or a signal dependent on the actual tool temperature, compared with a reference, the error varying the cutting speed or feed drive of the machine to maintain the temperature constant. The error signal may vary the speed of an electric motor through a thyrisitor control arrangement, adjust a change speed mechanism such as a Kopp variator, or may control the admission of fluid to a hydraulic system. The tool temperature may be sensed by a thermocouple. The arrangement may be utilized as a method of testing the machinability of material by operating on a workpiece of the material until steady state conditions are achieved, and using the temperature control system as a measure of the machinability of the material. Pneumatic control of the driving mechanism is envisaged in the Specification. Where electrical control is utilized a relay may be employed to cut off any error signals below a determined value.
