In order to achieve the precision and efficient processing of nanocomposite ceramics, the ultrasound-aided electrolytic in process dressing method was proposed. But how to realize grinding parameter optimization, that is, the maximum processing efficiency, on the premise of the assurance of best workpiece quality is a problem that needs to be solved urgently.

Electrolytic machining is a method of removing material from metal surfaces by electrolytic etching, and electrolytic grinding is a process that adds mechanical grinding process to this. Typically, with the electrolytic elution processes, some anodic byproducts that inhibit the elution will be formed and in some cases the elution can completely ...

ELID grinding consists of three steps : (i) the precision truing of a micro-grain grinding wheel; (ii) the pre-dressing process of the wheel by electrolysis and (iii) the grinding process using electrolytic in-process dressing. The ELID grinding process (step (iii)) took 10 min for each grinding wheel. After ELID grinding, the surface roughness ...

Machining is a term used to describe a variety of material removal processes in which a cutting tool removes unwanted material from a workpiece to produce the desired shape. The workpiece is typically cut from a larger piece of stock, which is available in a variety of standard shapes, such as flat sheets, solid bars, hollow tubes, and shaped beams.

Electrolytic in-process dressing (ELID) is the most suitable process for dressing metal-bonded grinding wheels during the grinding process. Nano-surface finish can be achieved only when chip removal is done at the atomic level.

Electrolytic In-Process Dressing (ELID-) grinding is a method for grinding hard and difficult to machine materials, such as ceramics in mirror surface quality. This is possible due to the chip absorbing ability of the generated oxide layer during electrolysis and the self-controlled sharpening process that results from a combination of ...

Dressing is the process to condition the grinding wheel surface to achieve appropriate abrasive particle protru-sion so as to achieve designated grinding behavior. In recent years, a new in-process dressing technique called Electrolytic In-Process Dressing (ELID) used on grind-ing wheels with metal bonded super abrasives (diamond

Many advantages make electrolytic in-process dressing (ELID) grinding desirable for cutting hard and brittle material with high surface requirements. The self-electrolytic in-process dressing property in ELID grinding is also largely responsible for the shorter wear life and lower forming accuracy of the grinding wheel. In ELID grinding, except for traditional mechanical wear, the electrolytic ...

Electrolytic in-process dressing (ELID) grinding, which uses a metal-reinforced granulating wheel, is a strategy for accomplishing a mirror surface appearance on hard and fragile materials (Biswas, 2009). The procedure of ELID Grinding has a concurrent electrolytic response and granulating activity.

Chemical grinding is only a dipping operation, and the operation is simple; while electrolytic grinding and polishing require large-capacity direct current, and the current counter electrode must be reasonably set to accurately control the current and voltage. The operation process is complicated and the quality control is difficult.

Grinding and polishing is the final stage in the metallographic sample preparation process and consists of several steps. Each step uses finer abrasive than the previous one, the ultimate goal being to produce a deformation-free, scratch-free and highly reflective sample surface. The sample may need to be examined, either etched or unetched, to ...

Data are presented covering the effect of several variables on grinding rate for the electrolytic grinding process. The relative amount of material removal due to electrolysis and due to conventional grinding action was investigated.
