1. Single unit activity was recorded with the microneurography technique from sixteen spindle afferents and one Golgi tendon organ afferent originating from the forearm extensor muscles. Impulse rates were studied while subjects performed unobstructed aiming movements at the wrist in eight different directions 45 deg apart. In addition, similar imposed movements were performed while the subject...

1. The main purpose of this study was to collate population data on the firing characteristics of muscle afferents recorded chronically during normal stepping in cats. 2. Ensemble firing profiles of forty-seven muscle spindle and tendon organ afferents were compiled from stored data. The relationships between the firing profiles and the displacement and force signals were analysed with the help...

Residual stress in the end-milled subsurface can significantly affect fatigue performance of material. In end-milling process, generation residual is extremely complex, which closely related to spindle speed, feed per tooth and cutting force. Thus, it crucial elucidate influence speed on force stress, also correlation between terms tooth. According this, dry Inconel HX was performed by climb-mi...

purpose: to assess the histopathological and immunohistochemical features of orbital spindle cell tumors. methods: a descriptive, retrospective study was performed on 63 pathology reports on all types of orbital spindle cell tumors at the pathology department of farabi hospital between 1995 and 2005. immunohistochemistry studies for different markers, such as smooth muscle actin, desmin, s100 p...

Abstract The machining parameter during milling process plays a very important role in the of various materials. In this study parameters such as feed, speed spindle, depth cut has been studied considering AA7075 aluminum material and its effect on surface roughness workpiece have studied. These types are commonly used aerospace, defense, marine automotive industries due to high strength weight...

The present study investigates the effects of machining parameters and tool coating during drilling a GLARE® hybrid aerospace material on cutting forces, hole quality generation harmful dust particles. tests were conducted using twist drills with diamond-like carbon (DLC), Cristall without coating. Obtained results indicate that feed, in contrast to spindle speed, has an important effect thrust...

Abstract The Taguchi optimization technique was utilized to determine the optimal milling parameters that can be used in end face CNC operation of polypropylene+5wt.% quarry dust using high-speed steel (HSS) tool. Three input i.e. feed rate (f), cutting speed spindle (N) and depth cut (d c ) were optimized while considering surface roughness (Ra) machined composite material removal (MRR) during...

A method is presented to estimate the cutting forces in real time within machine tools for any spindle speed, force profile, tool type, and conditions. Before cutting, a metrology suite instrumented holder are used induce magnetic during rotation, while on-machine vibrations, forces, error motions measured various combinations of speeds forces. physics-inspired data-driven model then relates ac...
