ABSTRACT
• This project "design and fabrication of wood router machine are using pantograph and four
bar mechanism” is a designed and is used mainly to cut wood, plastic, mild steel plates in to
any shapes with desired accuracy and correctness.
• This machine consists of the traditional cutting equipment along with a pantograph which is
a mechanical linkage connected in a manner based on parallelogram and which is further
used for copying and scaling line drawing and complex images.
• The working principle of four biomechanism which one link is fixed and other are pivoted.
These other links move according to the movement of the tracing link.
This is a low cost and high valuable apparatus. In this
project, a model of “design and fabrication of wood
router machine using pantograph and four bar
mechanism” will be designed using CAD packageslike
AutoCAD, pro-e,solid works etc.
taking into consideration of the commercially
available components would lead to a diminish aped
performance of the machine resulting into a poor
INTRODUCTION
The pantograph is one of the fascinating mechanisms of engineering equipment ever
invented and in some form or other; it should be part of every engineering shop's
equipment.
Engraving lines in two dimensions are just one of its functions, more sophisticated
versions work in two dimensions and will copy complicated two-dimensional designs
and engineered components, enlarging or reducing them in size as required. A
pantograph is a simple and powerful tool, which can broaden the scope of artwork and
crafting.
We can scale the images with a pantograph depending on how the parts are measured
and assembled. The pantograph calculates the distances between its pivot points and
resizes the image as the "algorithm" for creating the final copy.
The pantograph in the analogy would produce a copy smaller than the original. The
percentage of enlargement of the pantograph was provided by changing the distances
between the pivot points.
PROBLEM STATEMENT
The idea behind design of low-cost CNC Milling Machine is to full fill the demand of CNC
machines from small scale to large scale industries with optimized low cost. A major new
development in computer technology is the availability of low-cost open source hardware,
such as the Arduino microcontroller. An advantage of open source hardware is that a wide
variety of ready-to-use software is available for them on the Web; therefore, the prototyping
and development times are drastically reduced. Moreover, a wide range of low-cost
interfaces and accessories such as Arduino shields are also available. However, for the
development of low-cost models of CNC machines, such tools may be quite adequate from
the viewpoint of machine control.

DISCRIPTION
The pantograph mechanism is used to design and fabricate a milling machine which could traverse on any contour
provided that stylus is moved along the same on any already existing object. Using such kind of manipulator we
can generate the de-scaled replica of the object or we can say it to be a copying machine which can be employed
in mass production with economical production/machining cost.
The 3-DOF in this manipulator adds a feature to increase or decrease the depth of engrave and thus can be used in
metal engraving industries or wood carving industries to copy the engraved wooden design.
At the end-effecter we can replace the cutter by a welding torch or a paint brush to perform the desired typical
operation with very ease and accuracy. The only constraints are its poor dynamic performance but our kinematic
analysis shows it to be perfect for light and slow speed operation.
The three degree of freedom in this manipulator adds a feature to increase or decrease the depth of engrave and
thus can be used in metal engraving industries or wood carving industries to copy the engraved design.
PROCESS OF IMPLEMENTATION
ADVANTAGES
• 1. The main advantage is the pantograph is portable and it can move in
180degree of rotation.
• 2. The scaling factor can be adjusted according to the need with slight changes
in the design depending on if the scale has to be reduced or enlarge.
• 3. The design of the portable pantograph four bar mechanism such that, it reduce
the weight up to 10times.
• 4. The cost is also reducing to a great extent.
EXPECTED MODEL
APPLICATION
• You can carry out almost all machining operations with the CNC machining centers.
• You can also carry out all the turning operations such as facing, boring, turning, grooving,
knurling, and threading on your CNC turning centers.
• On your CNC grinders you can carry out the grinding of the internal diameter, outer
diameter, and also the flat surfaces.
• The Contour Grinding technology enables you to grind surfaces of all shapes.
CONCLUSION
This machine can be used in small and medium scale industries. This machine is mainly used in wood fabrication
oriented industries. The material can be removed at any shape like oval, rectangular, ellipse, square, circular,
pentagon, hexagon shapes etc. This machine is used to guide the cutting tools. This machine is used for
reproduction of maps and plans on enlarged or reduced scale.

  • 8. DISCRIPTION The pantograph mechanism is used to design and fabricate a milling machine which could traverse on any contour provided that stylus is moved along the same on any already existing object. Using such kind of manipulator we can generate the de-scaled replica of the object or we can say it to be a copying machine which can be employed in mass production with economical production/machining cost. The 3-DOF in this manipulator adds a feature to increase or decrease the depth of engrave and thus can be used in metal engraving industries or wood carving industries to copy the engraved wooden design. At the end-effecter we can replace the cutter by a welding torch or a paint brush to perform the desired typical operation with very ease and accuracy. The only constraints are its poor dynamic performance but our kinematic analysis shows it to be perfect for light and slow speed operation. The three degree of freedom in this manipulator adds a feature to increase or decrease the depth of engrave and thus can be used in metal engraving industries or wood carving industries to copy the engraved design.
  • 10. ADVANTAGES • 1. The main advantage is the pantograph is portable and it can move in 180degree of rotation. • 2. The scaling factor can be adjusted according to the need with slight changes in the design depending on if the scale has to be reduced or enlarge. • 3. The design of the portable pantograph four bar mechanism such that, it reduce the weight up to 10times. • 4. The cost is also reducing to a great extent.
  • 12. APPLICATION • You can carry out almost all machining operations with the CNC machining centers. • You can also carry out all the turning operations such as facing, boring, turning, grooving, knurling, and threading on your CNC turning centers. • On your CNC grinders you can carry out the grinding of the internal diameter, outer diameter, and also the flat surfaces. • The Contour Grinding technology enables you to grind surfaces of all shapes.
  • 13. CONCLUSION This machine can be used in small and medium scale industries. This machine is mainly used in wood fabrication oriented industries. The material can be removed at any shape like oval, rectangular, ellipse, square, circular, pentagon, hexagon shapes etc. This machine is used to guide the cutting tools. This machine is used for reproduction of maps and plans on enlarged or reduced scale.
