Investigating 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 کامل[The influence of posture during flower-cutting on the strength of flower-cutters' apprehension].
OBJECTIVE Musculoskeletal disorders, particularly carpal tunnel syndrome, have been one of the most important public health problems during recent years. It is the leading cause of occupational morbidity in Colombia, the flower industry being one of the areas of work having the highest incidence. This study was thus aimed at ascertaining whether flower-cutters' strength of apprehension has been...
متن کاملNumerical Simulation of Oxidation Effects in Laser Cutting of Mild Steels
A numerical model is developed to simulate the process of oxygen-assisted laser cutting of mild steels. The coupled concentration and energy balance equations are solved by a control-volume based computational scheme while the velocity field is obtained by the analytical boundary theory. The enthalpy method is adopted to trace the free boundary of phase change. The steady-state simulation resul...
متن کاملScheduling Coast Guard District Cutters
United States Coast Guard (USCG) districts schedule cutters 180 feet or less in length to weekly statuses (statuses is USCG jargon for assignments) from which they primarily respond to calls for search and rescue, law enforcement, and pollution control. The First Coast Guard District, based in Boston, has one of the largest scheduling problems: Each of 16 cutters is assigned weekly to one of si...
متن کاملMicrostructure-based 3d Fe Modeling for Micro Cutting Ferritic- Pearlitic Carbon Steels
The mechanics of the cutting process on the microscopic level differ fundamentally from the conventional macro cutting. For example, the tool edge radius influences the cutting mechanism in micro machining significantly with regard to the effective rake angle, the minimum chip thickness, the dominance of ploughing, and the related elasto-plastic deformation of the workpiece material. These phen...
