Abstract:

Machine tool accuracy is greatly influenced by geometric and thermal errors that cause positioning deviations within its working volume. Conventionally, these two error sources are treated separately, with distinct procedures employed for their characterization and correction. This research proposes a unified volumetric error compensation approach in terms of a calibration procedure and error compensation model, which considers geometric and thermal errors as a single error source that exhibits temporal variation primarily due to changes in the machine’s thermal state.

Volumetric errors are the major contributor to the dimensional errors of a workpiece in precision machining. Error compensation technique is a cost-effective way to reduce volumetric errors. Accurate modeling of volumetric errors is a prerequisite of error compensation. In this paper, a volumetric error model was proposed by using neural networks based on ant colony algorithm. Finally, a volumetric error compensation system was developed based on the proposed model, and which has been applied to a CNC machine tool in daily production.

Abstract:

Verification systems are needed for periodic verification and calibration of robots and machine tools to maintain and increase their accuracy. One of the ways to verify the volumetric accuracy of a manufacturing system is to measure the position of its head (X, Y, Z coordinates) using measurement systems that provide these results with the appropriate precision. The laser interferometer provides results with accuracy levels suitable for robot and machine tool verification applications. However, to measure the head position of manufacturing systems (X, Y, Z coordinates), the use of laser interf

Abstract:

Latest trend in increasing the performance characteristics of precision machines is reducing error in machines. Today research is focused on Machine tool accuracy. The effect of thermal error contributes to major part of 70% of volumetric error. The present study aims to establish a new compensation method for CNC Turning centre. Selection of proper temperature variables is a great task in thermal error compensation. In this paper 3 thermal process variables namely spindle speed; temperature and time are used to create thermal error models. Using ANSYS simulation experiments are created.

Abstract:

This research reports on error identification and compensation of a special purpose CNC machine. The kinematic model of the machine was developed using rigid body kinematics and small angle approximation of the axes of the machine through homogenous transform matrices, and the equations describing the volumetric errors. The machine was calibrated to measure the axes errors, which were used in the kinematic model in order to determine compensation values. The model was evaluated by means of direct measurements of axis movements using a laser interferometer, as well as in cutting tests, where a

Abstract:

New network tariffs designed to recover grid operating costs can introduce up to a 500% increase in charges for some households. A transition from volumetric to peak-load-based tariffs will require targeted policy measures such as clear price signals, information about household electricity consumption and temporary compensation or mitigation mechanisms.

Abstract:

Abstract Volumetric verification is increasing daily its relevance. However, as it is based on mathematical compensation, it does not model only the influence of the machine tool’s geometric error to verify, but the total error of the data. Among all error sources, thermal variations due to changes in environmental conditions strongly affect MT position accuracy. This paper studies how verification changes affect compensation functions based on a modification of machine tool kinematic model and a generator of synthetic data. It takes into consideration the influence of the measurement noise on

Abstract:

Kinematics theory for a multi-body system is used to analyse translational joint error, rotational joint error, and quadrature error in a spherical grinding system. A virtual grinding point method is proposed that is based on process features, and the feasibility as well as effectiveness of this method is demonstrated. A volumetric error model of the grinding system is created and the compensation method is coded into a control computer program. A laser interferometer is used to experimentally measure the error both with and without the proposed error compensation scheme. The experimental resu

In this paper, a new volumetric-error measurement method incorporating of three derived error models, two-step measurement procedure, and use of telescoping ball-bar was proposed for three major types of five-axis machine tools. Comparing to the methods currently used in industry, the proposed method provides the advantages of low cost, easy setup, and high e

Abstract:

The error caused by measurement itself directly affects the accuracy of models. The error caused by the failure to follow the Bryan principle in the process of measuring the volumetric error of the machine tool makes the geometric accuracy of the machine tool after compensation less than the ideal effect. In this paper, it is proposed that the measurement error will be caused by the non coincidence of the measurement point and the tool position point in the measurement of linear axis error. According to Bryan principle, the relationship between the center point of the reflective mirror of the
