OPTIMIZATION OF FAST TOOL SERVO DIAMOND TURNING FOR ENHANCING GEOMETRICAL ACCURACY AND SURFACE QUALITY OF FREEFORM OPTICS

Optimization of fast tool servo diamond turning for enhancing geometrical accuracy and surface quality of freeform optics

Fast tool servo (FTS) in ultra-precision diamond turning is an efficient technique for high-precision fabrication of freeform optics.However, the currently adopted constant scheme for control point sampling takes no account of the shape variation of the desired surface, which might lose some micro features KMI and result in low form accuracy and no

Onset of Asymptomatic Skeletal Metastatic Disease seen on Dxa

ABSTRACT: Objective: Skeletal metastases are common in cancers such as those of the breast, prostate, and lung and most often diagnosed when they come to clinical attention due to pain.We describe two cases of asymptomatic metastatic skeletal disease diagnosed on routine dual-energy X-ray absorptiometry (DXA) evaluation, prompting intervention for

The changing face of contemporary translation studies through polydisciplinary lenses: Possibilities and caveats

This paper offers a meta-reflection of contemporary translation studies (TS) through tracing its polydisciplinary tensions which are approached as both formative forces as well as hindrances.Taking a form of an argumentative essay employing the methods of a reflexive introspection, synthesis and evaluation, the principal aim is to address the poten
