April 11, 2022, 1:46 a.m. Updated 35 {"title": ["", "Modularised Platform Technology of Twin Axis PECM Machine Tool"], "description": ["", "\nPulsed Electrochemical Machining (pECM) uses the principles of ECM but pulsed\nvoltage/current providing; lower current improving energy usage, lower material removal rate\n& better surface finish, vastly improved dimensional accuracy machining hard/high strength,\ntemperature resistant materials, smaller machining gaps between cathode & workpiece to\nproduce finer detail, follows geometry of the cathode reducing cathode\nreshaping/regeneration, has less metal Hydroxide waste (hard to dispose of). The problem\nfacing the conventional ECM market is components must have 2-3mm additional material\nprior to machining to enable removal of defects/achieve final geometry, wasting expensive\nmaterials. Components can be nearer net shape if manufactured using pECM.\nTypically compressor/turbine blades are forged to oversized dimensions, machined by\nconventional methods (milling/turning) or, one side at a time using single cathode (axis) ECM\nleaving a \u201cpip\u201d which needs removing via tumbling /hand grinding/polishing with no control\nover accuracy of final geometry/dimensions. A twin cathode (axis) ECM would machine both\nsides of the blade simultaneously, leaving no pip. There is no known production of twin axis\nECM machine tools in the world nor any twin axis pECM. A twin axis pECM would be the\nideal machining method to complete manufacture of compressor/turbine blades to final\ntolerances/geometries & surface finish. If twin axis pECM could be developed, it would have\na huge impact on the global aerospace/turbine market.\nThe proposed study involves exploration of the ECM market in aerospace (civil & military)\nfor the manufacture of compressor/turbine blades & to see if development of a modularised\nplatform technology of pECM machines, capable of duel sided machining (twin axis/multi\naxis) can be adapted to meet industrial applications at a competitive price & be viable,\nresearch & investigate the use of metal dipped plastic as cathodes to provide cheaper\ntooling/manufacturing costs\n\n"], "extra_text": ["", "\n\n\n\n"], "status": ["", "Closed"]}
