Abstract

The tuming process is one of the machining process which is quite important in the industrialized world. One of the machining process aspect is a cutting force which has price that can be determined by the value of various aspects, such as variable process (cutting speed, feeding and depth of cut), material and cutting tool geometry, workpiece material and used machine tools. Because of so many parameters that can influence the magnitude of cutting forces, the calculation of cutting force theoretically can not get the accurate results. Due to some flaws of cutting force calculations theoretically, it is necessary to design and create a tool that can be used to help measuring the cutting forces that occurs, the tool namely as dynamometer. The dynamometer is considered as a cantiever that given a force at the end of its free shape. Dynamometer is used on the cutting tools, so that when the tuming process happens, the cutting tools which cut the workpiece will make the deflection on the dynamometer . the deflection of the dynamometer will raise the needle of deviation on the dial indicator. From the value of the gauge needle deviation will be converted to force unit by multiplying the number with calibration factor so that cutting force in machining process will be known. The characteristics which is planned in this making of dynamometer is the maximum force which is given in the end of cutting tools is 800 N, so that the tension which is arranged on the elastic dynamometer is 45 N/mm2 , the dimension that is suitable with the condition of the cutting tools, is the diameter of outside elastic cantilever which has size 27 mm, the shape and dimension which has arrangged, the maximum deflection on the dynamometer is 53 pm. Next procedure, is the manufacturing process in this step the implementation should be concemed is to create each of the components to the assembly process. The components are cantilever elastic rod and the dynamometer bodies an elastic rod clamp, making the dynamometer bodies, the choosen material is a Steel beam which is cut to the dimensions of 115 x 115 x 90 mm to adjust the dimensions of the planning. The process undertaken of manufacture are grinding, milling, dnlling and tapping to make the bolt holes. While, in the manufacture of elastic rod cantilever is divided into two parts, the elastic and solid parts that serve as a cutting tool holder. Whereas, the elastic portion is made from the Steel pipes and for the solid part is made of a cylindrical Steel rod. The dimensions and the size of the elastic rod in accrdance with the workspace dimensions of the engine and dynamometer bodies as a clamp with the elastic outer diameter is 33 mm and an inner diameter is 27 mm. Then, calibration and testing process before the dynamometer which has been arranged and ready to use . The calibration process is doing the static loading method, second providing a gradual load on the direction in which the force acts. Then the measurement by reducing the load with the same value. A comparative analysis of the regression line between two variables, namely the load and deflection are shown dial gauge, to the get sensitivity of the dynamometer. From the result of this calibration can be obtained the value of multiplier factor for the converted value in the gauge needle is 12,36 N/pm. The value of this multiplier factor will be an accuracy value of dynamometer where is whenever every 1 pm changes there is a force change with the amount of 12,36 N.
