Finite Element Analysis of Hardened Steel Cutting

Hard machining, as attractive replacement for many rough and finish grinding operation, generates high cutting forces and temperature that enhance tool wear when act together. Therefore, the tool geometry and machining parameters have to be carefully optimized for a given material. Because of high cost and time consuming experimental work up-to-date advanced software for modeling and simulation...

Copper Precipitation Hardened, High Strength, Weldable Steel

Steel containing 0.03% carbon, 1.35% copper and 0.84% nickel had yield strength in the 540-625 MPa (78-90 Ksi) range depending on thickness, ultimate tensile strength in the 625-690 MPa (90100 Ksi) range, and 25-30% elongation when air cooled after hot rolling. No brittle heat-affected zone was formed during manual or automatic submerged arc welding without pre-heating or postheating. The fract...

Ultraprecision sculpturing of hardened steel by applying elliptical vibration cutting

Elliptical vibration cutting technology is well-known for its excellent performance in ultraprecision machining of steel materials with single crystal diamond tools. This paper presents two approaches to attain high-performance microand macro-scale sculpturing for steel materials by utilizing elliptical vibration cutting. In order to attain free-form sculpturing in macro-scale, a 4-axis control...

On machining of hardened AISI D2 steel with PCBN tools

This paper describes an experimental investigation on machining of a difficult-to-cut material, AISI D2 steel of hardness 62 HRC with PCBN tools. It was found that the most feasible feeds and speeds fall in the ranges 0.08–0.20 mm/rev and 70–120 m/min, respectively and that most of the tested PCBN tools reached the end of life mainly due to flank wear. The highest acceptable values of tool life...
