4. ABSTRACT A lathe tool dynamometer that can evaluate fixed cutting forces using level of strain gauges has been designed and developed. The designed lathe tool dynamometer is capable for computing the forces on cutting tool during operations such as facing, turning. The sensing system measures the deflection In strain gauges and these signals are modified into other quantity and computed in the form of forces on the display system.

5. O bjectives The purpose of the tool is save the time cost of production to get the better output which cannot be obtained with hand tools.

6. Working principle of lathe tool dynamo meter ? Lathe tool dynamo meter is a equipment which used for observing the amount of load acting on the tool while operation by using strain gauges.

7. sensor The sensor is designed in such a way that it can be rigidly mounted on the tool post, and the cutting tool can be fixed to the sensor directly.

8. METHODOLOGY Measurement of cutting force by using electrical strain gauge is the best technique available. The natural frequency of the tool holder of lathe tool dynamometer will be calculated. Stress calculation will be carried out for the safe design of lathe tool dynamometer .

9. PROBLEM IDENTIFICATION Difficulty was that differences caused by changes of the sensitivity among the measuring bridges by changing the balance points of the circuits. Relatively high variation in the accuracy of horizontal and vertical force components developed due to large effect of cross sensitivity, zero drift, and variations in voltage supply and temperatures

10. RESULTS AND DISCUSSION T he feed forces and depth of cut is directly proportional to cutting forces. Cutting forces depend upon feed rate of tool cutting forces increase as feed rate increases.

11. conclusion The cutting forces are measured by using electrical strain gauge is the best technique available. As per cutting analysis of forces, it has concluded that the cutting & feed forces is directly proportional to depth of cut & feed rate of tool and inversely proportional to feed/rev.
