“…Uhlmann et al examined the error sources of freeform surface milling processes, for the decisive factors that significantly influence the productivity and the workpiece quality. They concluded that each error sources proportion may be related to the deviations measured in particular regions of the machined surface [27]. Scandiffio et al focused an investigation of free-form milling of hard material AISI D6 tool steel using a ball-end cemented carbide cutting tool and created a guideline for cutting tools life [28].…”

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.

“…Workpieces measured using the coordinate measuring technique can be produced by means of machining or rapid prototyping techniques. Measured products can be characterized by regular geometric shapes or can be composed of free-form surfaces [1] to [3]. Measurements of free-form surfaces can be divided into data acquisition and data processing [4].…”

“…These errors are for example linked to the Computer Aided Manufacturing (CAM) programs (tool path computation), to the CNC (interpolation, inverse kinematical transformation, axis follow-up), to the static, dynamic and thermal errors of the machine tool (machine geometry) or to process related errors (actual tool geometry, tool deflection, vibrations, chip formation, etc.). As it is can be seen in [26], the tool path interpolation can be one of the main source of problem regarding the productivity and the quality of the free form surface machining process. 5-axis surface machining has several advantages compared to 3-axis surface machining such as increased material removal rate, tool length reduction, better surface finish, etc.…”
