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...
متن کاملInvestigating Flank Wear and Cutting Force on Hard Steels by CBN Cutting Tool by Turning
In this research work a series of tests were conducted in order to determine flank wear and cutting force FY on hard AISI 440 C martensitic stainless steel and SCM 440 alloy steels. The operating parameters are cutting speed, feed rate and a constant depth of cut to investigate the flank wear and cutting force. No cutting fluid was used during the turning process. The cutting tool used was CBN ...
متن کاملInfluence of Workpiece Material on Tool Wear Performance and Tribofilm Formation in Machining Hardened Steel
In addition to the bulk properties of a workpiece material, characteristics of the tribofilms formed as a result of workpiece material mass transfer to the friction surface play a significant role in friction control. This is especially true in cutting of hardened materials, where it is very difficult to use liquid based lubricants. To better understand wear performance and the formation of ben...
متن کاملPrediction of flank wear by using back propagation neural network modeling when cutting hardened H-13 steel with chamfered and honed CBN tools
Productivity and quality in the finish turning of hardened steels can be improved by utilizing predicted performance of the cutting tools. This paper combines predictive machining approach with neural network modeling of tool flank wear in order to estimate performance of chamfered and honed Cubic Boron Nitride (CBN) tools for a variety of cutting conditions. Experimental work has been performe...
متن کاملUltraprecision 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...
