Machining of composite materials for the production of bolt holes is essential in the assembly of the structural frames of many industrial applications of GFRP. Abrasive water jet cutting technology has been used in industry for such purposes. This technology has procured many overlapping applications and as the life of the joint in the assemble structure can be critically affected by the quality of the holes, it is thus important for the industry to understand the application of abrasive water jet cutting process on GFRP composite materials. The aim of the present work is to to assess the influence of abrasive water jet machining parameters on hole making process of woven laminated GFRP material. Statistical approach was used to understand the effects of the predicted variables on the response variables. Analysis of variance (ANOVA) was performed to isolate the effects of the parameters affecting the hole making in abrasive water jet. The result shows that cutting feed, water jet pressure, standoff distance and abrasive flow rate are influential parameters upon the response variables of the abrasive water jet cutting process of GFRP composite, type 3240.

Abrasive Water Jet Cutting

Abrasive water jet (AWJ) is one of the most advanced and valuable non-traditional machining processes because of its massive advantages of removing metals ranging from hard to soft. This paper focused on studying the influence of jet pressure, feed rate and standoff distance on surface roughness during cutting carbon steel using abrasive water jet cutting. A surface roughness device assessed the surface roughness by performing sixteen experiments to identify the distinct texture of the surface. Based on the experiences, the best surface roughness value was 3.14 μm at jet pressure 300 MPa, standoff distance 4mm and feed rate 30 mm/min. The Taguchi method was introduced to implement the experiments and indicate the most influential process parameters on average surface roughness. The experimental results reveal that feed rate has a significant effect on average surface roughness.

Abrasive Water Jet Cutting

In this paper research elements regarding the effect of water pressure variation on cut surfaces quality are presented in the field of abrasive water jet cutting of materials hard to process by machining such as austenitic stainless steels, in this case with a thickness of 20 mm. Selection of the optimal cutting process based on technical and economic criteria takes into consideration the type and thickness of the targeted material and also the physical and geometrical quality requirements. The present paper contains experimental research results regarding abrasive water jet cutting of austenitic stainless steel EN 1.4306 (ASTM 304 L) at different values of water pressure. The abrasive material used is Garnet with particle granulation 80 Mesh. By making roughness measurements and hardness examinations of the cut surface an evaluation will be made of the surface quality defining the optimal pressure values.
