4. INTRODUCTION
Grinding is a machining process that utilizes abrasives
for the removal of material. The sharp edges of abrasive grains
act as cutting tool that remove material in the form of mostly
powder or extremely fine chips.
 Straight & Tapered Grinding Wheel
 Abrasive Material
 SiC
 Al2 O3
4BE Final Presentation

5. Dressing is an operation performed on the grinding
wheel with an aim to restore the cutting ability. The basic
principle for dressing is the generation and exposure of the new
cutting edges on the surface of the wheel.
 Dressing sticks
 Crush rolls
 Diamond Tool

The applied WEDD technology, as dressing
method to be used directly on the grinding
machine, proved to be suitable, flexible,
effective and reliable, ensuring a significant
improvement on the dressability of metal
bonded diamond wheels.

EDM/ELID is used that takes advantage of
conductivity of the bond material and erode
binder with discharges (sparks). The wheel
dressed has better roundness (form) and
grinding with it takes place with enhanced
accuracy and surface finish

N. P. Maniar,
D. P.
Vakharia,
(IJESER)
In his work in design & development of fixture for CNC
explained that fixture design is one of the most important
design tasks during process design for a new product
development since it involves defining the locations and
orientations of parts during assembly processes as well as
providing physical support, which can greatly affect product
dimensional variations and process yield.

“Design related
study of fixture”
G. P. Sharma,
S. C. Chadda,
A. Saraf
(IJER)
In design related study of fixture explained that fixture is an
important element in most of the manufacturing processes
and related to machining errors the role of fixture is very
crucial. Studies pertaining to the design of machining
fixture are generally of two categories i.e. fixture analysis
and fixture synthesis.

(IJERGS)
Fixture provides the manufacturer for flexibility in holding
forces and to optimize design for machine operation as well
as process function ability. Fixtures are the tool used to
locate and hold the work piece in position during the
manufacturing process. Fixtures are used to hold the parts
firmly which are to be machined, it is used to produce the
duplicate parts accurately 8BE Final Presentation

21. RESULT
(MAX. STRESS)
As shown above fig. the total maximum stress value is 103 N/mm in
compression but we have taken 40 times more load than the actual load so our
design it safe and that stress is negligible.

23. RESULT & CONCLUSION
• The maximum deformation value is 5.6 mm & it
doesn’t affect on our mechanism and assembly while
it working.
• The total maximum stress value is 103 N/mm in
compression but we have taken 40 times more load
than the actual load so our design it safe and that
stress is negligible.
• As per our calculation & observations we have
reduced dressing time upto 50 % & also reduced
labour efforts

This project is very useful in the small-scale
industries for the purpose of dressing operation on tapered
wheel with 500 angle. This is the new innovation of the
dressing mechanism with low cost and less complication
in design. This mechanism has more accuracy in operation
because of dovetail sliding joint. It’s also very simple in
operation. It can be handled by low skilled worker with
effective operation.
There is also chance to future research on it and
make full automatic with more accuracy.
