Oblique-cut LiNbO_3 microchannel spatial light modulator

Optics Letters, 1982
Significant improvements in the spatial resolution, framing speed, optical quality, and space-domain image-processing capabilities of the microchannel spatial light modulator have been realized by employing oblique-cut rather than z-cut LiNbO(3) crystals, high-strip-current (250-microA) microchannel plates, and an acceleration grid in the gap of the ...

Precision prediction of cutting force in oblique cutting operation

The International Journal of Advanced Manufacturing Technology, 2015
This paper presented a general model for predicting the cutting forces in oblique cutting operation with respect to vector transformation derived from orthogonal cutting process. The developed model is based on that the fundamental mechanics of the friction relationship between tool and material (chip) at the primary and secondary shear zones are the ...

A study of oblique cutting for different low cutting speeds

Journal of Materials Processing Technology, 2001
Abstract In this paper, the finite deformation theory and an updated Lagrangian formulation (ULF) were used to describe the oblique cutting process. Either the tool geometrical location condition or the strain energy density constant was combined with the twin node processing method to be adopted as the chip separation criterion.

Construction of a dynamic cutting force model for oblique cutting

Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 2009
This work presents a dynamic cutting force model of oblique cutting by considering the oblique cutting operation, the relationship among cutting angles, the effects of wave removal and wave cutting on the fluctuation of shear angle, the variation of the instantaneous uncut chip thickness, and the variation of the chip flow angle.

On Oblique Cutting of Cellular Elastic materials

International Journal of Fracture, 1998
It is shown that the previously developed model for the direct cutting of cellular plane allows to investigate also the more general case of 3D oblique cutting after replacing the coefficient of friction at the cutter faces by its effective value. The numerical results illustrate the advantages and disadvantages of the oblique cutting regime.

A study of an oblique cutting model

Journal of Materials Processing Technology, 1999
Abstract The finite deformation theory and the updated Lagrangian formulation (ULF) were used to describe the oblique cutting process in an attempt to develop an oblique cutting elastic–plastic finite-element analytical model. In this paper, an elastic–plastic stiffness matrix equation was first derived.

Burr formation and fracture in oblique cutting

Journal of Materials Processing Technology, 1996
Industrial summary To improve productivity in the machining of parts, advanced technology for deburri~g becomes more important. In a computer-integrated manufacturing system, the prediction of burr formation or fracture is required. To apply a burr-formation model for orthogonal cutting to a realistic oblique-machining case, a modified model for burr ...

Oblique-cut longitudinal electrooptic modulators

IEEE Journal of Quantum Electronics, 1971
The minimum longitudinal half-wave voltages are calculated for five oxygen-octahedral crystals with large linear electrooptic coefficients. The predicted values range from 11 kV (LiTaO 3 ) to 75 V (BaTiO 3 ). Experimental results have been obtained for LiNbO 3 and LiTaO 3 .

Oblique machining with a single cutting edge

International Journal of Machine Tool Design and Research, 1964
Abstract The problem of defining the rake angle which controls the cutting process in oblique machining is considered. Experimental results are presented from which it is concluded that the rake angle normal to the cutting edge is of greatest significance.

Predicting Cutting Forces for Oblique Machining Conditions

Proceedings of the Institution of Mechanical Engineers, 1982
Using orthogonal (plane strain) machining theory together with certain simplifying assumptions based on experimental observations it is shown how the three components of cutting force in oblique machining can be predicted from a knowledge of the work material flow stress and thermal properties and the cutting conditions.
