Abstract:
The contour precision has been an important CNC machine accuracy index along with the increase of high precision complex parts NC machining. The error of perpendicularity and the mismatch error of position loop gains among linked axes are regarded as the prime reasons to bring about CNC machine contour error. After analyzing the influence of the error of orthogonal axes perpendicularity to CNC machine contour precision, a compensation approach is set up that the following error is corrected in each sampling period, by introducing a perpendicularity deflection parameter.

Abstract:
As an important sensor of an unmanned surface vehicle (USV), an electro-optical device is usually used to detect ships and obstacles in USV autonomous navigation and collision avoidance. However, the installation perpendicularity error of the electro-optical device greatly impacts the line-of-sight (LOS) stability control. This error is difficult to eliminate through mechanical calibration because the platform inertial navigation axis cannot be led out. This study aims to establish the model for the perpendicularity error of electro-optical devices during circumferential scanning and analyze i

Abstract:
DBB was originally manufactured and proposed for checking the accuracy of NC machine tools. The device can also be used to study the relations between motion error of trace and the machine motion error for the purpose of error compensation. The nominal angle obtained through rotation feed rate and sampling time was adopted instead of actual angle which cannot be measured by the device. This project examined in details the effect of the angle deviation problem caused by non-perpendicularity between the movements in axis X and axis Y. The analysis and calculation verified that a squareness devia

Abstract:
The factors influencing the reliability and durability of the joint between a shaft and a rubber reinforced seal are analyzed. It has been established that the theory of tightness of such joints has not yet been developed. The quality of a joint is usually assessed by the amount of leakage. It has been revealed that the amount of leakage depends on the materials from which the shaft and seal are manufactured, the roughness of the shaft surface, the presence of dust in the friction zone, the quality of the sealed liquid, and the operating temperature. In addition, the durability of the work is

Abstract:
An Auto-Compensation of inertial navigation system (INS) based on improved single-axis rotation has been proposed in the paper. Inertial Measurement Unit (IMU) is tilt mounted, e.g. neither perpendicularly, nor coaxially, with the rotation axis. Analysis and derivation show that this angle arrangement of IMU can restrain the expansion of the system errors caused by IMU. Simulations demonstrated the coincidence of the theoretical analysis and the system performances

Abstract:
Laser beams are usually unstable in terms of their pointing direction because of fluctuations of the resonant cavity. This angular fluctuation of laser beams can be somewhat reduced with a servomechanism.1,2 My approach uses an optical system capable of self-compensating the angular fluctuation of the laser. Because no servomechanism is required, the beam stabilizer reacts instantaneously. The stabilizer essentially uses the self-compensation principle. The input beam is first divided into two perpendicularly polarized beams, that then combine to form the output beam. Because the angular fluct

This paper describes the performance of the ultrasonic normal incidence method as a technique for inspection of the middle zone of wall thickness of LSAW (Longitude Submerged Arc Welding) steel pipes. Generally, the tandem method is applied to LSAW seam inspection of the middle zone of wall thickness. However, it is difficult to adjust the locations and angles of each probe. Therefore, the normal incidence method using one probe for inspection of the middle zone of wall thickness was studied. Because the probe arrangement is simple, it is possible to reduce the time and effort required to adju
