Answer / malayappan

Rake is angle of tool. If you take a sing point cutting too
like a turning tool of a lathe it has front rake angle,
back rake angle and side rake angle and all are necessary
for improved machining and geting relieved the chip that is
coming out. In fact all these angle vary they are not same.
Rack may be a shelf you have in your house or ordering of
too the as said in a earlier answer

Answer / rakesh

rake is the term used in case of a single point cutting tool
for operation like turning in lathe.
It is the angle between the normal to the machining surface
and the rake face of the tool.
-Higher the angle will decrease the cutting force and
increase the surface finish of the workpiece,
-This angle can be from 0-90 degree ,but generally its
recommended to 15-30 degree rake anle(back rake angle).
-Because increasing the rake angle,removes the material from
the tool that will support the cutting edge of the tool and
help in heat distribution from the tool to the atmoshpere.

Answer / guest

rake is the cutting tools one of the angle, rack is the one
of the gear which transmitte rotary motion to linear motion

Answer / avi

one rake is cutting tool angle, and another one rack is a gear with infinite pitch circle rad or we can say it is a straight toothed gear like used in lathe machine..........
