THE
CUTTING FLUID INFLUENCE IN THE INLET ENGINE VALVES GRINDING |
| Abstract
: |
|
In this paper is presented an experimental research in which the grinding
of inlet engine valves was improved by the adoption of the most effective
cutting fluid type, matching the new requirements of cutting fluid
application. Four different types of cutting fluids (cutting oil and three
different types of soluble oils) were analyzed. As evaluation parameters of
the performance of the cutting fluids, the roughness, the grinding wheel
wear and the workpiece residual stress were measured. As a conclusion, the
cutting oil is the most adequate cutting fluid to be used, due to its
tendency in reducing the roughness, the wheel wear, due to its higher
lubricity and ability in keeping the wheel sharp for longer periods of time.
The main factor of choice was the compressive residual stress generated
during all grinding cycles by this type of cutting fluid, which can increase
the fatigue life and the mechanical proprieties of the ground component.
