Evaluation of Geometric Errors in a Horizontal Lathe using the Indirect Calibration Method

Abstract

The aim of this study is to assess the geometric errors in a horizontal lathe, specifically focusing on the Indirect Calibration method. The research aims to provide insights into the quality and performance of the lathe's metrological processes. The application of the Indirect Calibration method to assess geometric errors in a mechanical lathe contributes to the field of metrology by offering a unique approach to error evaluation. The research involves the setup of an experimental structure according to the Indirect Calibration method. Data collection, storage of a linear variable differential transformer displacement (LVDT), application of the Least Squares Method, and statistical analysis with analysis of variance (ANOVA) are key research methods. The study reveals significant geometric errors in the mechanical lathe, with variations in error magnitude across different transverse positions. The position of the lathe's carriage significantly influences the errors. These findings provide valuable insights for the quality and precision of machined parts. The Indirect Calibration method can help manufacturers identify optimal machining positions, contributing to improved product quality.
