ABSTRACT
Roundness Measuring Tool is a machine that is used to make measurements that are shown to check the roundness of an object or to find out whether an object is really round or not when viewed carefully using a measuring instrument. In carrying out measurements, it must be supported by technology that can make it easier for operators to use and analyze measurement results by involving programming and monitoring microcontroller is a solution for developing in measurement roundness. So that the control system has an important role as a roundness measuring device that has an automatic way of working so that data retrieval is faster and more effective than manually. In this study, the roundness measuring instrument contained a control system that was used to control the measuring instrument. The control system in this tool is a system that regulates the automatic movement of the roundness measuring instrument. Where the function of this automatic motion control system is to measure the test object using a chuck as a clamp, the dial indicator is directed by the X and Y axes to the data collection point on the test object connected to the driving motor. The Y axis moves translationally to direct the dial indicator on the "arm" to the pickup point which moves automatically depending on the selected data capture mode, then the dial indicator starts taking measurement data until measurement data collection is complete, then the motor moves from top to bottom to perform data retrieval in a reversible manner. So that the test modes are varied, namely spiral and ring. It was found that the translational speed of the screw shaft in the vertical motion is 0.025 m/s and the horizontal linear speed is 0.026 m/s. For the standard deviation of accuracy on this tool with each mode, spiral and ring modes are 0.
