The various parameters that are important in turning are, A. Machining Feed: There are different feeds available on the lathe machine, which are varied to determine the effect of feed on the cutting forces. B. Depth of Cut: The depth of cut can be varied with the help of micrometer dial on the cross-slide. C. Approach Angle: Different approach angles will be taken for the analysis. Other tool geometry will be kept constant. Tool material will also be kept same. II. MACHINES/ INSTRUMENTS REQUIRED The details of machines and equipment available in workshop on which the project will be carried out are given below: A.

Dynamometer: For the measurement of cutting forces a three component strain gauge type lathe tool dynamometer is used for the present work. It consists of orthogonal ring and used to measure force values in three directions, one vertical direction two force components in longitude and transverse direction. The assembly consists of four octagonal rings arranged at right angles to each other and strain gauges which are fixed between two thick plates. Range of force measurement is 0-500 kg in all directions. Two rings are used to measure forces in feed direction and the other two in axial direction and all the four rings for the vertical component of cutting force. All the rings are identical in shape and can measure forces in three mutual perpendicular directions The Dynamometer is divided into the following subunits. Sensing unit: the sensing unit consists of four orthogonal rings with strain gauges cemented on arms. The unit accurately senses forces in three axes to the bridge circuit. Bridge balancing unit: The bridge balancing unit consists of power supply used to supply power to three bridge circuits. Measuring unit: A standard DC motors are provided to measure the output of the bridge unit directions in terms of kg. Some instructions are necessary for bridge balancing unit before performing the operations.

Abstract— The present research paper is focused on the
analysis of optimum cutting conditions to get lowest cutting
forces in turning of mild steel material. The experimental
result analysis showed that the optimum combination of
various input factors as type of insert type, work piece
material, Approach Angle, feed and depth of cut. Further,
the confirmation tests are conducted and the results are
found to be increased with increment of feed and depth of
