Abstract
Machining Rapidly Solidified aluminium (RSA) 6061, a widely used optical material by Ultra-high precision diamond turning, has enabled high accuracy and surface integrity. However, improved quality and productivity require precision surface and machining process monitoring because the duo has a great influence on machine part performance. The study presented in this paper investigates the effects of cutting parameters (i.e., depth of cut, feed rate and cutting speed) on machining output variables (surface roughness and acoustic emission potentials) during ultra-high precision diamond turning of RSA 6061. With the aid of Box-Behnken design (BBD), a response surface methodology, and the analysis of variance (ANOVA), the correlation between cutting parameters and machining output variables were analyzed and modeled. The results showed that both surface roughness and acoustic emission potentials are greatly influenced by feed rate and cutting speed. For a better-quality surface roughness and low acoustic emission during ultra-high precision diamond turning of RSA 6061, high cutting speed and low feed rates are the right combinations and vice versa.
Highlights
With the widespread application of optics and electronic data developments in some areas of technology such as aerospace, defense, military, biomedical, electronics, astronomy etc., optical components are being produced with high-surfaces quality which has extended and intensify the degree of precision necessity for machining and evaluation [1]
In order to carry out statistical analysis, it was discovered statistically that transformation is required for these two responses

Summary
With the widespread application of optics and electronic data developments in some areas of technology such as aerospace, defense, military, biomedical, electronics, astronomy etc., optical components are being produced with high-surfaces quality which has extended and intensify the degree of precision necessity for machining and evaluation [1]. Since surface generation involves many mechanisms [2, 3], different experimental methods have been adopted to analyze surface roughness mechanism in the static state, while a number of advanced models have been employed to attain material surfaces with preset roughness parameters being proposed [3,4,5] Some of these surface generation mechanisms are still far researched due to the absence of direct access to the breach between surfaces during frictional contact. Basic optical materials utilized in the assembling of optics are steel, aluminum and tungsten carbide These materials are chosen because of their heat obstruction, introspective properties, and trademark quality. Be that as it may, the utilization of fine small-scale micro-structure rapidly
