Modelling manufacturing errors in machining of thermoplastics
International Journal of Computer Applications in Technology, 2008A polyamide 66 (PA66) plate was machined by milling, and the deformation of the machined surface was acquired by using a coordinate-measuring machine. The plastic material was characterised in terms of density, thermal and thermo-mechanical properties to evaluate the distribution of the material properties across the thickness. As a result, the moulded

Computer Simulation Of Manufacturing Errors
SPIE Proceedings, 1988A technique has been developed for analyzing the effect on image quality of various optical surface errors. The technique can be applied to surface errors typically seen in optical fabrication, such as rolled edges or zonal errors or discontinuities. The technique allows rapid assessment of surface error effects for known errors as well as for typical ...

Transmission Error Calculation Based on Manufacturing Errors and Load
Advanced Materials Research, 2014A valid mathematic model is introduced to study the calculation of gear meshing transmission error, which is based on the manufacturing error and gear teeth deformation. Subsequently, take a pair of specific gear for example;The transmission error curves are obtained by the calculation model.

Effects of Assembly and Manufacturing Errors on Transmission Error of Planetary Gears
6th International Power Transmission and Gearing Conference: Advancing Power Transmission Into the 21st Century, 1992Abstract Transforming 2K-H type planetary gears with three planet gears into an equivalent model with many degrees of freedom, in a plane perpendicular to the input and output shafts, the loci of the displacement of a floating sun gear were analyzed theoretically by using the equivalent model. The theoretical locus of the displacement of

Design for manufacturing the elastic pivots with special reference to manufacturing error
International Journal of Machine Tools and Manufacture, 1994Abstract The stiffness of an elastic pivot, a kind of torsional hinge, must usually be small in the direction of axial rotation and high in all other directions. In some applications, such as the gimbal suspension of the tuned gyroscope in an inertial guidance system, the size of the elastic pivot is small, and consequently the pivot becomes very ...

Deviation modeling of manufactured surfaces from a perspective of manufacturing errors
The International Journal of Advanced Manufacturing Technology, 2018Assembly analysis, as an important step in the product design stage, provides verifications of product design with specific requirements. The manufactured surfaces that participate in the analysis result from different manufacturing methods and show inconsistency with the designed surfaces due to the effects of numerous manufacturing errors.

Volumetric Error Control in Layered Manufacturing
Volume 4: 19th Design for Manufacturing and the Life Cycle Conference; 8th International Conference on Micro- and Nanosystems, 2014This paper presents a novel method for adaptive slicing based on volumetric error considerations for Layered Manufacturing (LM). In the general LM process uses constant layer thickness throughout the part height which leads to poor surface finish at inclined surfaces.
