the micro wire electrical discharge machining (micro wire-edm) process is a modern machining process with various applications in manufacturing micro-parts. the recast layer remaining on the machined surfaces is an inevitable complication of this process. this layer can subsequently affect the machined parts performance. to optimize the recast layer in the micro wire-edm of the molybdenum micro...

PVC frame cutting process by guillotine is a common method that attracted attention of car parts and PVC decorating furniture producers. In this paper, the effects of main parameters such as cutting speed, lubricants and cutting frame holder pressure force on PVC frame section surface smoothness is investigated by experimental methods on a specified PVC frame sample and then by FEM simulation u...

turning of hardened steels using a single point cutting tool has replaced the cylindrical grinding now as it offers attractive benefits in terms of lower equipment costs, shorter set up time, fewer process setups, higher material removal rate, better surface quality and elimination of cutting fluids compared to cylindrical grinding. in order to obtain desired surface quality by machining, prope...

The dynamics of the cutting process are investigated. Using the increase of cutting depth as a control parameter, two diierent cutting regimes are observed. In the rst regime, which is observed at small cutting depths, complex, high-dimensional dynamics occur. In the second cutting regime, observed for deeper cuts, low dimensional dynamics are typical. The second cutting regime is usually ident...

manufacturing process frequently employs optimization of machining parameters in order to improve product quality as well as to enhance productivity. the material removal rate is a significant indicator of the productivity and cost efficiency of the process. taguchi method has been implemented for assessing favorable (optimal) machining condition during the machining of nylon by considering thr...

most of the materials used in the industry of aero-engine components generally consist of titaniumalloys. advanced materials, because of their excellent combination of high specific strength, lightweight and general corrosion resistance. in fact, chemical wear resistance of aero-engine alloyprovides a serious challenge for cutting tool material during the machining process. the reductionin cutt...

The main aim of this paper is to study the material removal phenomenon using the finite element method (FEM) analysis for orthogonal cutting, and the impact of cutting speed variation on the chip formation, stress and plastic deformation. We have explored different constitutive models describing the tool-workpiece interaction. The Johnson-Cook constitutive model with damage initiation and damag...
