IMPROVING ACCURACY OF ELECTROCHEMICAL MACHINING PROCESSES

Mathematical Modelling of Electrochemical Machining Processes

The solution to free boundary problems arising from electrochemical machining processes is considered. A mathematical description of the machining process is presented with particular consideration given to its electrochemical properties and to the appropriateness of its treatment as a potential problem with Dirichlet boundary conditions. A number of different machining configurations are consi...

Improving Machining Accuracy Using Smart Materials

Both economical and ecological factors might encourage conventional machines to continue in service by healing tool vibration problems. Higher productivity in automated manufacturing system brought to the attention the importance of machine tool error elimination. Various factors might affect the machining process (Merritt, 1965), some of them are non-measurable, and others might change in real...

Improving Cnc Machining Accuracy through Thermal Model Based Control

The United States Army has a requirement to machine munitions to strict tolerances so that the munitions will launch properly and the explosives will detonate correctly. High precision parts require machine tools to operate with a high degree of accuracy in order to produce parts within tolerance. Unfortunately, thermal expansion, tool wear and other impediments make high accuracy machining, es...

Concepts of Sustainable Machining Processes

Sustainable production as a global word, content important elements on all the fields as well as machining processes. Machining can be performed either on conventional or nowadays modern CNC way. Novel machining processes are based on CNC programmable technologies containing elements as CAD, CAM, etc. To define sustainable production as the creation of goods, using processes and systems, we hav...
