Investigation on partitioned distribution of cutting heat and cutting temperature in micro cutting

International Journal of Mechatronics and Manufacturing Systems, 2016
Although the low cutting temperature and a small amount of heat generated are occurred in micro cutting, they are comparably high in a small unit cutting area or zone, and consequent affect the micro cutting process significantly. Thus, such low cutting temperature in micro cutting can cause an excessively dissipated heat into cutting process including

Influence of cut front temperature profile on cutting process

ICALEO 2011: 30th International Congress on Laser Materials Processing, Laser Microprocessing and Nanomanufacturing, 2011
Laser cutting of metals is one of the most common applications in industrial manufacturing. Due to this, every improvement of process efficiency and the consequential increase of cutting velocity while maintaining the quality implies a high economic potential.

DYNAMICS OF CUTTING TOOL TEMPERATURES DURING CUTTING PROCESS

Experimental Heat Transfer, 1994
An experimental study is performed to measure temperature variation of a carbide insert during metal cutting by means of fine thermocouples connected to a data acquisition system. A semiempiriad equation is developed based on transient conduction solutions combined with experimental data to predict temperature-time history in the cutting tool during ...

Measurements of Temperatures in Metal Cutting

Journal of Fluids Engineering, 1946
Abstract Measurements of the heat developed in a metal-cutting operation, as well as investigation of cutting and chip temperatures by the authors have brought out that the chip temperature is uniform at the higher cutting speeds when all other conditions are kept constant.

Temperature controlled laser cutting

ICALEO '82: Proceedings of the Materials Processing Symposium, 1982
Any laser process is characterized by a large number of parameters affecting its performances. Since some of these parameters may change during the process and consequently result in reduced performances, a means for a real time process control is required.

Coolants and Cutting Tool Temperatures

1975
A recently developed metallographic method of estimating temperature gradients in cutting tools has been used to demonstrate the influence of coolants on the distribution of temperature in tools used to cut nickel and iron at relatively high cutting speeds.

Temperatures in Orthogonal Metal Cutting

Proceedings of the Institution of Mechanical Engineers, 1963
The results of a photographic technique for the determination of the complete temperature distribution in the orthogonal metal cutting process are presented; they are found to disagree with previous theoretical predictions. The temperatures along the tool rake face are of particular interest because they are thought to affect the wear of the cutting ...

TEMPERATURE RISE IN A CUTTING TOOL

International Journal of Production Research, 1965
SUMMARY Determination of time of temperature rise in a cutting tool is of significance in machining of metals. It is particularly so in milling where the cutting is intermittent, thus allowing time for dissipation of heat between successive cuts. Many researches have been directed to this problem but their findings vary widely within the range of 0-2 ...

Simplified calculation of the cutting temperature for grinding and razor cutting

2017
Simplified analytical dependencies are obtained to determine the cutting temperature during grinding and blade machining, taking into accountthe heat balance flowing into the workpiece and the formed chips. It has been found by calculations that in the case of multi-pass grinding, almost allthe heat generated during grinding goes into the workpiece. It
