Abrasive jet micromachining ajm is a promising technology for processing brittle materials.

Abrasive jet micromachining parameters. Ajm has a progressively important influence on the machining technology market. Abrasive jet machining ajm is a manufacturing technology based on erosion localization and intensification. A study of effect of process parameters of abrasive jet machining bhaskar chandra1 department of mechanical and automobile engineering itm university sector 23 a gurgaon 122017 haryana india. The aim was to fabricate the maximum number of fins per unit length with the highest aspect ratio into al6061 t6 in order to maximize heat transfer potential. Process parameters of abrasive jet maching ajm are factors that influence its metal removal rate mrr. Water jet machining uses water mixed with abrasive materials projected with high pressure typically 07 mpa and focused on the workpiece. Abrasive jet machining ajm is the process of material removal from a work piece by the application of a high speed stream of abrasive particles carried in a gas or air medium from a nozzle. Abrasive waterjet machining awjm as a technological method was developed in 1930 in the mining industry compared with awjm the abrasive slurry jet machining asjm or sometimes abrasive water suspension jet awsjm operates at roughly two orders of magnitude lower pressure and uses a premixed slurry concentration. Powder blasting or abrasive jet machining is a technique in which a particle jet typically al 2 o 3 particles of 330 mm is directed toward a target for mechanical material removal. Based on an experimental study of hole and groove machining on an amorphous glass by abrasive air jet the effects of processing parameters on the produced structure profile such as groove width or hole diameter depth of cut and kerf taper angle are analyzed. In low pressure abrasive slurry jet micro machining asjm an aqueous slurry of abrasive particles such as aluminum oxide al 2 o 3 and tungsten oxide wo 3 is used to erode features in a target workpiecebecause the jet is highly focused with a divergence of less than 10 asjm is well suited for the fabrication of features such as micro holes and micro channels. The abrasive water jet micro machining of high aspect ratio free standing structures such as fins used in heat sinks was investigated. It is a fast. The following are some of the important process parameters of abrasive jet machining. Get an overview of ajm process mechanism parameters equipment mrr accuracy capability pros and cons applications controlling etc.

In a machining process metal removal rate mrr is the volume of metal removed from a given workpiece in unit time.
