| Abstract | Abrasive Fluid Machining (AFM) Abrasive Flow Machining is a grinding technology that uses a machine hydraulic cylinder to push elastic colloid abrasives to flow on the complex shapes of the workpiece or surfaces such aspipe grooves to remove burrs or chamfers on the workpiece surface. This elasticcolloid abrasive is a viscoelastic polymer r with a certain amount of superhard abrasive added, so it will produce a grinding effect when it passes through the surface of the workpiece in a confined space. In order to achievethe processing quality of the workpiece surface, the operating parameters assigned by the AFM equipment are adjusted to achieve a polishing effect. The adjustable operating process parameters on t he human-machine interface of the AFM equipment include colloid abrasive pressure, colloid abrasive flow rate, and colloid abrasive target flow rate (time). The composition, type, characteristics of the elastic colloidal abrasive and the fixture design of the workpiece will also affect the output quality of AFM (surface roughness and improvement rate). The work -piece material of this paper experiment is industrial ceramics. The type of work -piece material (metal & non-metal) and the type of colloidal abrasive selected are also key points to consider in the AFM process. The AFM equipment used in this research is the NK-150/100 machine made by Meiji Technology Co., Ltd., a domestic precision ceramic manufacturer. The work -piece is the alumina ceramic tube. The experimental method is conducted based on the design parameters that affect the AFM processing quality, and then measure the surface roughness and improvement rate of the workpiece by com- parison of the degree of influence of each parameter. |
