INTRODUCTION
 A Milling is the machining process of using rotary cutters to remove material from
a work piece by advancing (or feeding) in a direction at an angle with the axis of
the tool.
 A dynamometer or "dyno" for short, is a device for measuring force, torque,
or power. For example, the power produced by an engine, motor or other
rotating prime mover can be calculated by simultaneously measuring torque
and rotational speed (RPM).

OBJECTIVES
 To Performance and Analysis of Milling Machine with an Dynamometer.
 To be calculated by simultaneously measuring torque and rotational speed (RPM).
 To making a effective Analysis system with low cost.
 To with advances in technology, milling dynamometers are increasingly used for
the accurate measurement of forces and for optimizing the machining process.
 A milling dynamometer is a multi-component dynamometer that is used to
measure forces during the use of the machine tool.

WORKING PRINCIPLE OF MILLING DYNAMOMETER
 Turning Tool Force measuring system is most suitable for analyzing the acting force
on a lathe tool during turning operation. The system displays and indicate forces in X,
Y and Z direction on a lathe tool during turning operation.
 It comprises of triaxial piezo-electric measuring sensor.
 Signal from the sensor are transmitted to signal conditioner which in turn send those
to communication card, which further processed by using “LT” software.
 LT force measuring software to display all of the forces with graphics on computer
monitor

INFRARED THERMOMETER
 An infrared thermometer is a thermometer which infers temperature from a portion of
the thermal radiation sometimes called blackbody radiation emitted by the object being
measured.
 They are sometimes called laser thermometers as a laser is used to help aim the
thermometer, or non-contact thermometers or temperature guns, to describe the
device's ability to measure temperature from a distance.
 By knowing the amount of infrared energy emitted by the object and its emissivity, the
object's temperature can often be determined. Infrared thermometers are a subset of
devices known as "thermal radiation thermometers".
