Aerospace | Winbro Flow Grinding

Aircraft engine manufacturers use Abrasive Flow Machining (AFM) to improve airfoil surface finishes on compressor and turbine section blades and vanes. AFM is the preferred process to smooth airfoils on integrated components such as impellers, blisks, and IBR's when blades have been machined by profile milling or Electrolytic Machining (ECM).

Parametric Investigation of Gun Metal for Surface ...

The Abrasive Flow Machining process is a process that involves extruding an abrasivefilled semisolid media through a workpiece passage. The elements required for AFM process are the machine, workpiece fixture (tooling) and media. The machine used in AFM process hydraulically clamps the workholding fixtures between

Process Parameters of Abrasive Jet Machining « .

In a machining process, Metal Removal Rate (MRR) is the volume of metal removed from a given workpiece in unit time. The following are some of the important process parameters of abrasive jet machining: Abrasive mass flow rate. Nozzle tip distance. Gas Pressure. Velocity of abrasive particles. Mixing ratio. Abrasive grain size.

Abrasive machining Wikipedia

Mechanics of abrasive machining Abrasive machining works by forcing the abrasive particles, or grains, into the surface of the workpiece so that each particle cuts away a small bit of material. Abrasive machining is similar to conventional machining, such as milling or turning, because each of the abrasive particles acts like a miniature cutting tool.

Abrasive Flow Machining | SpringerLink

Machines for abrasive flow machining are available with extrusion pressure ranging from 700 to 22000 kPa with flow rates up to 380 l/min. Control systems can be added to monitor and control additional process parameters, such as temperature, viscosity, wear, and flow speed of the media.

NONTRADITIONAL MACHINING AND THERMAL CUTTING .

Abrasive Flow Machining (AFM) This process was developed in the 1960s to deburr and polish difficulttoreach areas using abrasive particles mixed in a viscoelastic polymer that is forced to flow through or around the part surfaces and edges. The polymer has the consistency of putty. Silicon carbide is a typical abrasive.

DESIGN OF MAGNETO ABRASIVE FLOW MACHINING | EPH ...

Abstract. Abrasive flow machining was developed as a method to deburr, polish, and chamfer very hard to reach surfaces with complex geometry . The volume of abrasive particles is carried by the abrasive fluid through the work piece.
