Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
The inevitability to machine hard materials and intricate shapes that are hard to be worked by traditional methods have stressed the need for non-traditional manufacturing processes specifically Wire Electro Discharge Machining (WEDM). WEDM encompasses intricate processes that include heating as well as cooling. The working parameters include pulse on time, pulse off time, table feed rate, flushing pressure, wire tension, wire velocity etc. has to be preferred suitably so that an optimized result can be attained. A single constraint has been chosen for the purpose of optimization to maximize the Metal Removal Rate (MRR). In this work a gear was machined out of EN31 material using the WEDM process and the process parameters such as pulse on time, peak current, wire feed rate and machining speed have been optimized using Simulated Annealing Algorithm and also using MATLAB based optimization. Simulated Annealing (SA) based optimization has been established to optimize the parameters in order to improve MRR. The objective function for metal removal rate is obtained based on the mathematical model.
