| Abstract | ||
| Research papers deals with using the strain gauge technique with equipment of dynamic strain measuring to get of maximum practical readings for "Shaping Tool Strain" which is known there physical and mechanical properties from beginning of cutting process to cutting stroke end .The" Merchant cycle" is using to analysis of cutting forces and measuring of label piece's dimensions that is getting at shear plane by changing cutting depth (2, 3 ,5 mm). The theoretical dynamic strain is determine by knowing mechanical properties of cutting material. The standard deviation (0.00016) and correction factor (0.3) that is referring to the ability of the technique can be using to improve cutting process and increase service life of tool cutting 30% approximately .The process is repeated with using one of lubricant liquid to determine dynamic strain values during lubrication and comparing with the previous one can be predict lubrication coefficient during cutting process that average value is (0.93) . | ||
