In Shaper machine tool is having reciprocating motion and
w/p is clamped on table which is stationary. It is mostly
suitable for light duty operation.In Shaping large cutting
force is transferred to tool.
In Planer machine tool is having stationary and w/p is
clamped on table which is reciprocating moton. It is mostly
suitable for Heavy duty operation.In planner large cutting
force is transferred to table.
1- Light duty machine used for finishing of material object.
2- job is stationery whereas cutting tool is moving.
While PLANER is
1- Heavy duty machine used when more finishing is required.
2-job can be moved but cutting tool is stationery.
If we measure the pressure of Air in duct with the help of
Pitot tube attached to manometer (pitot tube) whose one end
is in atmosphere and one end is in duct and manometer shows
some head whether it is Static head or Dynamic Head or
(Total head=Static head + dynamic Head). and if it is total
head in which static head is zero then how static head is
