The major parameters influential on the chip slenderness ratio were the feed rate
and the drill point angle, but the effect of the spindle speed was too small to be negligible; with decreasing the chip slenderness ratio, the thrust force and tool wear decreased, and also the removed chip morphology changed from shorter, brittle, and serrated to continuous, ductile, and free of serrated form.
The governing principle of solids feeding is: the higher the polymer friction on the feed-throat wall, and the lower the polymer friction on the screw, the better the feed rate
. Therefore, in the solids-feed area, the polymer must adhere to the barrel and slide on the screw for optimum feed rate
A combine harvester operates at maximum efficiency only if there is a substantially constant crop material feed rate
In their study the effects of spindle speed, cutting feed rate
and depth of cut on the surface roughness is analyzed and build a multiple regression model.
Thus, current study shows the influence of the input parameters; feed rate
and kind of materials on the responses G-ratio, surface roughness, and roundness.
Proto-LXRD type X ray stress analyzer was used to test the surface residual stresses of specimens with rotational speed being 1806 r/min and feed rate
being 28 mm/min.
The goal of this study is to obtain a mathematical model that relates the surface roughness to three cutting parameters in face milling, precisely to the cutting speed, feed rate
and depth of cut.
High surface roughness achieves at low speed keeping depth of cut 0.2mm and feed rate
as constant 0.10 mm/rev throughout the experimentation.
The feed package valve is designed so that the operator can throw the handle wide open on the directional control valve, allowing the feed package valve to control the drilling feed rate
. It contains a pressure compensated flow control that will provide a fixed feed rate
With a lot of contributing hands on a project, it's easy for the designated feed rate
to get skewed along the way.
Resawing with a dull blade wastes both time and materials, so replace the blade at the first signs of dullness--when the feed rate
slows or the cut starts to wander.
The V-bending was performed with varying temperature, fiber composition, feed rate
and tool radius.
