1) PROBLEM STATEMENT

            Excessive
wear of cutting tools during the machining process causes inaccuracy in
dimensions of the manufactured components thereby resulting in additional
costs. Hence, frequent inspection of cutting tool during the process becomes necessary.
But frequent monitoring of cutting tool by the operator during the process
results in increase in production time. Therefore a system is needed for
monitoring the tool wear in real time to reduce human interventions and
possibility of damage to the work piece due to excessive tool wear.

2) ABSTRACT

            In this report we have discussed
about selection of control factors, their levels and selection of data
acquisition system.

5) DATA ACQUISITION SYSTEM

1) Cutting force

Worn tool requires more force to
remove the same amount of material than the sharp tool. So, the cutting force
increases with increasing wear and is thus considered as one of the significant
parameters that can be measured easily to monitor tool wear 1.

2) Vibration

            Vibration is the main phenomenon which affects the tool
life and work piece quality, there are two main effects of vibration,

·        
The
traces of oscillation are indicated on the machined surface, which affects the
quality of the surface and the dimensional accuracy.

·        
It
affects negatively not only the operating life of the tool but also the tools
of the device – mainly the spindle 2.
