This report is a continuation of Progress Report No. 1 which was presented in 1947 before the Society. The investigation is principally concerned with the effects of cutting speed upon cutting temperature, chip thickness, and chip hardness, when stee

A substantial reduction in power consumption, an increase in tool life, more effective utilization of cutting fluids, and improved surface finish on the machined workpiece have been achieved by suitably controlling the length of tool-chip contact. Re

This paper presents metal-cutting data for the high-speed machining of copper and aluminum, each at two levels of purity, and over a range of workpiece temperatures from −326 deg F (80 deg K) to 550 deg F (560 deg K). It has been found that cutting

This paper presents an analysis of tool-wear data in terms of fundamental variables consistent with the nature of the contact and rubbing of clean metallic surfaces. Wear of cemented-carbide tools on the top surface is examined in the light of the me

A rapid, iterative method is presented for computing the distribution of temperature at the tool-chip interface. Calculation shows that the maximum temperature occurs at a point near the trailing edge of the contact when chips are produced at convent

The measurement of temperature distribution at the flank surface of a cutting tool is characterized by the extremely small extent of the surface over which the temperature field is explored. This paper describes a technique which makes use of a movin

The author presents some of the results of a series of tests in which the principal phase of study concerned the temperature developed at the contacting surface of the tool and the chip. This tool-chip interface temperature is referred to as the “c
