This document presents a kinematic study of a planer machine. It begins with an introduction that describes a planer machine as a tool that generates flat surfaces and cuts slots by moving the entire workpiece beneath a cutting head. It then describes the main parts of a planer machine including the bed, table, column, cross rail, and tool head. The document goes on to classify different types of planer machines, including double housing planers, open side planers, and divide type planers. It also describes the table drive and feeding mechanisms used in planer machines. Finally, it explains the operations of planning flat horizontal and vertical surfaces.

2. Introduction
Planer is machine that use to generate accurate flat
surfaces and cutting slots.
It is similar to a shaper, but it is larger than shaper
machine.
And with the entire workpiece moving beneath
the cutter,
The work table is moved back and forth on the
bed beneath the cutting head either by
mechanical means, such as a rack pinion gear ,or
by a hydraulic system.

3. Parts
BED
TABLE
COLUMN
CROSS RAIL
TOOL HEAD

5. Classification
Double housing planer
1. It is very old system machine.
2. Massive bed on which worktable
reciprocates.
3. A planer having two housings to support
the cross rail, with two heads on the cross rail.
4. two vertical columns on which two tool
head slides.

6. Open side planer:-
1.It consist of vertical column may be
mounted on the cross rail.
2.Column and cross rail consist of single and
double tool head.
3.Used for the machining of wide work
pieces.

7.  Divide type planer:-
1.It also called tandem planer.
2.Consist of two worktable.
3.Used for continuous mass production.
4.Two table are also join together when
needed.

8. Mechanism
The two important mechanisms of a planer
are :-
1.The table drive mechanism.
2.Feeding mechanism.
The different mechanisms used to drive the
table are:-
1.Open and cross belt drive .
2.Reversible motor drive.
3.Hydraulic drive.

9. Operation
Planning flat horizontal surfaces:-
while machining horizontal surfaces, the
work is given a reciprocating movement along
with the table and tool is fed crosswise to
complete the cut. Both the railheads may be
use for simultaneous removal of the metal
from two cutting edges.

10. • Planning vertical surface:-
The vertical surfaces of a work is planed by
adjusting the saddle horizontally along the
cross rail until the tool is in a position to give
the required depth of cut
