“…Electrolytic In-process Dressing(ELID for short)is a kind of wheel dressing technology that uses the electrolysis principle to make the metal matrix of metal bonded grinding wheel electrolytic in-process dressing [1]. In order to realize the high quality and stable ELID,the key technology is to keep the thickness of oxide layer on grinding wheel in determinate range [2]. But the thickness in-process is changing, the change of thickness could change the grinding status, which can't keep the course of working stable and get the good process quality.…”

“…For assuring surface machinability, atomic purity 97% Y 2 O 3 ceramic was machined by ultraprecision lapping process with in-process electrolytic dressing (IED) method. The ultra-precision lapping with IED method is widely used for surface machining of hard and brittle materials [6,9,10]. The lapping with IED was conducted by changing three main variables: applied force, wheel speed and machining time.…”

Prospects of Y 2 O 3 have been more extended as a great promising and creditable material for optical, electronic and mechanical purposes. Y 2 O 3 has been more observed as a fine ceramic which has great material properties: high light transparency, excellent thermal resistance and chemical inertness. But in terms of effective application of Y 2 O 3 , its hard and brittle nature needs to be overcome during the surface machining process. Therefore, the surface machining control of Y 2 O 3 should be conducted carefully. The evaluation for stable and continuous machining should also be investigated in various industrial fields as there are only limited studies on the subject. The lapping process with in-process electrolytic dressing (IED) is widely used for surface machining of hard and brittle materials. In this study, Y 2 O 3 surface machinability was evaluated by using the ultra-precision lapping process with IED method by changing three major variables: applied force, wheel speed and machining time. The most suitable value of Ra 92nm surface roughness was acquired with smooth surface quality from the following machining condition: 7kg of applied force, 60rpm of wheel speed and 30minutes of machining time. After the lapping process, the machining tendency and surface characteristics were analyzed with fracture toughness and Vickers hardness for the evaluation of Y 2 O 3 surface machinability.

“…It realizes on-line anode melting of metal-bonded grinding wheel through electrolysis. Oxide layer plays a very important role in ELID grinding [1,2,3],and the continuous change of its thickness results in the change of grinding conditions, which is not good for the stability of processing quality. Therefore, for the oxide layer, it is very important to change its electrochemical parameters such as voltage, duly ratio, rotating speed to control growth behaviors by measuring its thickness [4].…”

In order to measure thickness and Study on growth behaviors of oxide layers on grinding wheel surface in ELID, measurement system accuracy is verificated with laser and eddy current sensor for simulation measurement of oxide layers, Growth behaviour of oxide layers were measured in pre-dressing process, the results indicate inward growth speed of oxide layer is greater than outward growth speed along the radius of grinding wheel in the early , oxide layers keep linear growth and growth speed is the fastest; In the late ,inward growth speed of oxide layer slows, outward growth speed is slightly faster, but overall oxide layer growth slows down.
