Abstract
A compensating circuit which facilitates the use of the tool-work thermocouple for interface-temperature measurements is presented. The IR drop due to the flow of thermoelectric current in a closed circuit is used to nullify the parasitic emf introduced by dissimilar lead materials attached to the cutting insert. Conditions necessary to achieve complete compensation are explained and test results indicating the reliability of the method are given.Keywords
