“…Also, in WEDM operations, the analysis of the surface characteristics of machined workpiece is important. Mouralova et al [8] observed the surface morphology and topography on machined surface of the pure aluminium using various levels of the different machining parameters based on WEDM operation. Annebushan Singh and Kumar Sarma [9] investigated the surface characteristics on machined surfaces of MWCNT alumina composites based on different levels of various machining parameters in WEDM operation.…”

In this study, cutting rate and surface characteristic analysis in wire electrical discharge machining of aluminium bronze were investigated. Cutting rate analyses were performed according to Taguchi L18 (2 1 ×3 2) orthogonal array. Machining parameters such as wire type, duration between two pulses (BT) and pulse time (AT) were used as control factors. Raw data obtained for cutting rate were converted to S/N ratio values. Optimum levels of the machining parameters for cutting rate were determined using analysis of signal-to-noise (S/N) ratio. Significant machining parameters and their percentage contributions on results were obtained using Analysis of Variance (ANOVA). Regression analysis was performed to model the relationship between cutting rate and machining parameters. Analyses of surfaces machined of workpiece using both two wires for minimum and maximum cutting rate were observed using scanning electron microscope (SEM) and surface roughness device.

“…Therefore, many researchers use non-conventional wire electrical discharge machining process to enhance the material properties of aluminium alloys. K Mouralov et.al [1] analyzed the surface morphology and topography of pure aluminium after machined using WEDM. The damping behavior of WEDMed aluminium A356.2 alloy was evaluated and optimized by D S Prasad et.al [2].…”

An alloy of Aluminium has good properties and strong would be ideal for many applications. Among all the series of aluminium alloys, Al 7075 is extensively used in aircraft structures, gear shafts, and automotive industry because of its high strength and good corrosion resistance. The machining of Al 7075 can be done under annealed conditions and lubricants are used for operations. In the present work, Al 7075 was machined by using Wire Electric Discharge Machine (WEDM) and investigated the effect of operating parameters on reponses. The surface roughness and corrosion resistance are considered as responses. The operating parameters of WEDM considered in this work are pulse ON time, pulse OFF time, wire feed and servo voltage. Experiments were conducted according to the Taguchi’s design of orthogonal array L18 (21 x33 ). The values of surface roughness and corrosion pit potentials were observed for each experiment to understand the relationship. Multi-objective optimization for these process parameters has been carried out by Grey Relation Analysis (GRA). From this technique, the optimum combination of process parameters are obtained and corresponding values of surface roughness and corrosion pit potentials are found out. To validate the response table for grey relation grade obtained from GRA, Taguchi analysis was carried out which shows that the pulse on time is the most influencing parameter followed by pulse off time, wire feed and servo voltage.

The paper discusses evaluation of machining solutions for oversized thin-walled robotic portal component for conveyance workplaces. The following portal CNC machining centers have been selected. Firstly, a FSGC 300 "portal type" portal was proposed, with a 50000 mm "X" axis and Heidenhain control system, the second portal was a DMU 340 portal with the maximum axis "X" of 6000 mm and Siemens Sinumerik control system and the last portal was the VF-10 / 40 one, with the maximum axis "X" of 3048 mm and Fanuc control system. Further, the method of fixing a thin-walled robotic portal is designed and individual options are evaluated for their economy. The CAM software application used for programming the production was SolidWorks.
