Study on the Correlation of Workpiece Mechanical Properties From Compression and Cutting Tests

An internal state variable plasticity-based approach to determine dynamic loading history effects on material property in manufacturing processes

“…To overcome the disadvantages associated with conventional materials tests or machining tests, several integrated approaches [16,19] of the combined compression (including SHPB) test and machining test have been developed, in which the compression test is used to obtain material flow stress at low and moderate strains and strain rates, while machining tests for large strains and high strain rates.…”

“…For material deformations of much higher strain rates, a carefully designed machining test coupled with cutting models [15][16][17][18] may provide an effective method for estimating the average flow stress at a range of large strains and high strain rates. While the major disadvantage of a machining test is that the determined flow stress is an average and only valid in the range of large strains and high strain rates in cutting conditions.…”

Surface Integrity Characterization and Prediction in Machining of Hardened and Difficult-to-Machine Alloys: A State-of-Art Research Review and Analysis

“…An integrated approach based on compression and cutting experiments has also been developed to characterize the mechanical behavior of work materials in machining (Stevenson and Stephenson, 1995;Stevenson, 1997;Guo, 2003). It is also confirmed that the compression data can be correlated with the cutting data.…”

“…Average flow stress properties of the work material in a small range of large strain, high strain-rate and temperature in machining have been investigated using machining tests coupled with predictive machining models (Oxley, 1989;Stevenson, 1997;Shatla and Altan, 2000). Alternatively if one has an accurate constitutive model which fits the parameters of the model using a few cutting tests, it would be a perfect method.…”

The determination of ploughing force and its influence on material properties in metal cutting

“…Determination of cutting forces has long been recognized as one major process parameter for: (a) monitoring cutting tool conditions [1,2]; (b) predicting part and tool deflections [3,4]; (c) calculating material flow stresses [5][6][7][8][9][10][11]; (d) characterizing machining processes [12]; (e) designing machine tools; and (f) designing and selecting cutting tools. Practical cutting tools have a finite sharpness and contact between tool flank and the machined surface which induce ploughing force (parasitic force).…”
