“…In contrast, the damage due to delamination is usually a matter of greatest concern as it affects surface finish and work strength significantly leading to a great deal of part rejections. The delamination depends on not only fiber/matrix natures but also their adjacent properties [68,69]. Note that in standard FRP drilling, two mechanisms responsible for delamination may take place at both the entry and exit of the drilled hole periphery, which are well-known as "peel-up delamination" and "push-out delamination", respectively.…”

Hybrid composite stack, especially FRP/Ti assembly, is considered as an innovative structural configuration for manufacturing the key load-bearing components favoring energy saving in the aerospace industry. Several applications require mechanical drilling for finishing hybrid composite structures. The drilling operation of hybrid FRP/Ti composite, however, represents the most challenging task in modern manufacturing sectors due to the disparate natures of each constituent involved and the complexity to control tool-material interfaces during one single cutting shot. Special issues may arise from the severe subsurface damage, excessive interface consumption, rapid tool wear, etc. In this paper, a rigorous review concerning the state-of-the-art results and advances on drilling solutions of hybrid FRP/Ti composite was presented by referring to the wide comparisons among literature analyzes. The multiple aspects of cutting responses and physical phenomena generated when drilling these materials were precisely addressed. A special focus was made on the material removal modes and tool wear mechanisms dominating the bi-material interface consumption (BIC) with respect of investigating strategies used. The key conclusions from the literature review were drawn to point out the potential solutions and limitations to be necessarily overcome for reaching both (i) enhanced control of drilling operation, and (ii) better finish quality of FRP/Ti parts.

The present work discusses the modeling and optimization of tungsten inert gas arc welding (TIG) and graphical representation of weldment macrostructure zones' shape profiles based on full factorial design of experiments and response surface modeling. To accomplish the task, an in-house developed low cost arc image magnifying system was used. The welds were produced based on a full factorial design matrix of TIG process parameters such as welding current, arc length and traverse speed. Interaction effect plots of control factors indicated weld width is affected more by the welding arc length and current. Similar effects were also observed for depth of penetration and heat affected zone (HAZ). The full factorial experimental data was further analyzed for response surface regression modeling and the response surface regression equations were tested for a number of test case data for their adequacy. The response surface regression relations were further used to optimize the TIG welding process parameters using multi response optimization technique. A mapping scheme was also developed to map the TIG weldment cross-sections' macrostructure zones including that of HAZ. The responses predicted by the surface response regression equations for the test cases were further utilized for graphical representation of the welment shape profiles including that of HAZ. The modeling methodology, regression relations and weldment mapping scheme used in the present investigation were found to be adequate for the estimation of fusion and heat affected zone boundaries.

Latha et al [7] performed multiple regression analysis to model the drilling parameters involved in thedrilling of GFRP composites. They concluded that feed rate and drill diameter are the most influential parameters.…”

Composites are widely used in several applications ranging from automotive to aircraft industry due to their high strength to weight ratio. More often than not drilling on these composite laminates are conducted to serve some functional or aesthetic requirement. Delamination caused due to drilling pose a severe problem to the integrity of the structure. It is often not possible to develop an exact mathematical model to predict the delamination associated with such drilling. So, in this paper, an empirical model is developed based on the extensive experiments performed on polyester composite reinforced with chopped fibreglass. To account for the various parameters a Box-Behnken design of experiments is conducted for four parameters (material thickness, drill diameter, spindle speed, and feed rate) each having threedistinct levels. Genetic Algorithm (GA) and Particle Swarm Optimization (PSO) techniques are then used for predicting the global optimum (minimum delamination factor). The performance of both GA and PSO in terms of predicting the global optimum is found to be same. However, PSO converged much faster and required far lesser computational time.
