Glass Fiber Reinforced Thermoplastic composites (GFRTP) are an important, alternate to the conventional engineering materials due to their good application oriented properties.Drilling is unavoidable and an important operation used in automotive and aerospace industries in the assembly stage. The reduction of thrust force is needed to minimize the delamination. The paper examines the parameters which influence the thrust force on drilling Glass fiber reinforced polypropylene (GFR/PP). The experiments are conducted using Box-Bhenken experimental design method. Empirical relation is established for determining the thrust induced in drilling of GFRTP. The factors which affect the drilling process and their interaction are analyzed and presented in detail.

“…Generally bush shape depending upon proportion of work material thickness (t), and Drill bit diameter (d [3]. Ozler et al [4] and some other performed an experimental investigation of hole geometry in friction Drilling of AISI 1010 Steel when the feed decreasing and speed increases temperature at hole zone increase. Similarly, good geometry of washer was gets at more speed, and at the same time bushing height expanded.…”

 Abstract: Friction drilling is an advanced drilling process in which that can be utilize the heat produced between the workpiece and rotating drilling tool bit to soften the work material and producing a hole on it. In this investigation our interest is to choose work material is Al 7075-T351 to analyze the stress, strain, temperature and work material deformation in friction drilling. Al 7075-T351 square-tube materials were drilled on a computer numerical control (CNC) machine centre by friction drilling has analyzed at different rotational speed and feed rate through controlled operation tests. The temperatures in work piece and tool were more in Friction drilling. Simulation has required perceiving the material flow, stresses, temperatures, and strains. Those are tough to quantify experimentally through friction drilling. In this study, CATIA is used to design the tool model and the software which is used to simulate the performance of friction drilling is DEFORM-3D and effect of tool material speed and feed rate on shape of bushing formed is observed. Taguchi's technique L9 OrthogonalArray was used to analyze the optimum values. Signal to noise ratios also administered for optimization of parameters.

“…In friction drilling of difficult-to-machine materials, the bushing formation and tool wear are significant concerns that affected by spindle speed, feed rate and material properties of workpiece (Miller et al, 2007). Although, Ti-6Al-4V is play important role in industries and has different thermal properties from common difficult-to-machine materials such as AISI304, it seems need to conduct extensive studies (Ku et al, 2011;Ozler & Dogru, 2013;Mohammadshahi, 2013). In other word, study on effects of input parameters on output parameters and improve bushing height and shape and prolong tool life is necessary.…”

Friction drilling is a green hole-making process that zealously utilizes the heat generated from the friction between the rotating conical tool and workpiece to create a bushing without generating chip. The difficult-to-machine materials with unique metallurgical properties have been developed to meet the demands of extreme applications. However, the major challenges of friction drilling on difficult-to-machine materials are the hole diameter accuracy, petal formation and tool wear. In this study, the effects of process parameters such as spindle speed and feed rate on bushing height and shape, hardness and tool wear in friction drilling of titanium alloy Ti-6Al-4V were experimentally investigated using tungsten carbide tool. Optical photographs have also been analyzed for better understanding of the chipless friction drilling process for different parametric settings. Experimental results indicated that the spindle speed has great influences for achieving better bushing formation and prolong the tool life. It was confirmed that the low spindle speed and low feed rate have great influences for achieving better bushing shape and height, prolong tool life and lower hardness that located adjacent to the hole wall. It also was discovered that the low thermal conductivity of Ti-6Al-4V caused to improper increment of frictional heat and surface temperature. This disadvantage leads to unsatisfactory bushing formation. This work demonstrated the performances of chipless friction drilling used on difficult-to-machine material that can offer a great prospective for a new product design and manufacturing.
