Enhanced tool condition monitoring by statistical analysis in automatic machining of AISI 1045 steel using sintered carbide inserts

Semi-finishing and rough-shaping dry turning processes were performed on automatic lathe, applying three diverse measuring systems to the single point turning situation. Uncoated sintered carbide inserts were used in both processes, while TiC-TiN coated inserts were only used in the rough-shaping processes. The outputs measured were associated with the state and wear rate of the cutting tools. The behaviour of the useful power output, the tool-holder shank vibrations and the surface roughness vs. pass number were investigated. Wear was assessed by the roughness checks on work pieces in the semi-finishing processes, and by the lathe motor's electrical input together with the vibration level in the rough-shaping processes. In the present work, the single-factor analysis of variance for the responses - useful power, vibration acceleration and surface roughness - has been performed with the main aim to statistically make conclusions of the cutting speed significance and influence on the above mentioned responses. In addition, the regression models, i.e. the equations for the response variable (useful power and vibration acceleration) dependent on input variable (cutting speed) have been derived. Finally, a comparison of the responses, respectively for uncoated and coated inserts for the same cutting speeds (125 and 140 m/min), has been carried out by using the hypothesis testing procedure.
