the movement of the tool in boring is
parallel to the axis of rotation
the part of the lathe that rides on the ways and carries the cross-slide is called the
carriage
the metal removal rate is measured in units of
in3/min
to square the end of a workpiece on a lathe, this process is called
facing
the other name for cutoff is
parting
to drill a hole in a piece of metal, a process called what should be used first
center drilling
the structure of the lathe is called the
bed
to make a drilled hole straight and true to size, this process is used
reaming
the unit of measurement for feed is
in/revolution
in horizontal milling, when the movement of the feed is opposite to the movement of the teeth, the process is called
conventional milling
the broaching tool is considered as
multitooth
equation for material removal rate
volume of material removed/T = Lxwxt/T = n*pi*b*fd/T=12vfd
what is the material removal rate for those conditions for an N=600 rpm?
1.80 in3/min
V=n * pi * diamter
the tool holder on a lathe is mounted on the
cross-slide
turning takes place on the
outside diameter of the bar
the chip slides along the
rake face of the tool
the unpowered end of the lathe is called the
tailstock
surface feet per minute is the units of measure for
speed
in parting the movement of the tool is
perpendicular to the axis of rotation
the drilling process that makes a round hole true to size and direction is called
roaming
the term feed is measured in units of
inches per revolution
the part of the lathe that mounts on the carriage (saddle) is called the
cross slide
the structural support part of the lathe is called the
bed
during turning, the tool operates on the
outside diamter of the workpiece
the chip slides on the
rake face of the tool
squaring the end of a bar on the lathe is called
facing
to drill a large diameter hole in a metallic workpiece, the process should start with the process called
center drilling
in boring, the tool moves
parallel to the axis of rotation
in horizontal milling, when the tool and workpiece are moving in opposite directions, the process is called
conventional milling
a tool with flutes is used in the process called
milling
the speed V is measured in unit of
feet per minute
the metal removal process that has a one-pass translating tool where each tooth cuts slightly deeper than the previous one is called
broaching
the controls for a lathe are located in the
headstock
in order, the three steps to make the hole configuration shown in metal are
center drilling, drilling, countersinking
milling where the feed is againt rotation
conventional or up milling
milling where feed is with rotation
climb or down
