Purpose This study aims to investigate the effect of vibration on ceramic tools under dry cutting conditions and find optimum condition for hardened steel machining process in a computer numerical control (CNC) lathe machine. Design/methodology/approach In this research, an integrated fuzzy TOPSIS-based Taguchi L9 optimization model has been applied multi-objective (MOO) hard-turning responses....

Effective global manufacturing enterprises require internet-based tools and technologies to virtually integrate the efforts of customers, designers, and manufacturers who work in separate office buildings or on separate continents. We present the framework for an internetaccessible, feature-based, CNC programming environment. The environment empowers users from different geographical sites to c...

The literature on human turning preferences is inconsistent. While the few studies with children below 14 years of age uniformly describe an overall left-turning (counterclockwise) tendency, a recent Internet study with more than 1500 adults found a right-sided (clockwise) bias. We set out to investigate spontaneous turning behaviour in children age 5-3 years and, based on neuropsychiatric work...

Caenorhabditis elegans exhibits spontaneous motility in isotropic environments, characterized by periods of forward movements punctuated at random by turning movements. Here, we study the statistics of turning movements-deep Omega-shaped bends-exhibited by swimming worms. We show that the durations of intervals between successive Omega-turns are uncorrelated with one another and are effectively...

Computer numerical control (CNC) involves machines controlled by electronic systems designed to accept numerical data and other instructions, usually in a coded form. CNC machines are more productive than conventional equipment and consequently produce parts at less cost and higher accuracy even when the higher investment is considered. This article proposes an educational scheme for designing ...
