Oblique ulnar shortening osteotomy by a single saw cut

The Journal of Hand Surgery, 1996
Ulnar shortening osteotomy is an effective treatment in patients with ulnar impaction syndrome. Accurate shortening and bony apposition can be obtained for a wide range of shortening lengths with a single-cut osteotomy technique. The saw kef produced by a single saw pass cuts a bony defect with parallel walls. The amount of shortening produced by using

Mechanics of cutting model for simulated oblique rotary tool cutting processes

Journal of Materials Processing Technology, 1991
Abstract Rotary tool cutting processes are described and simulated as ‘orthogonal’ and ‘oblique’. A modified thin shear zone mechanics of cutting model for driven and self-propelled ‘oblique’ rotary cutting tool processes are developed and experimentally verified, qualitatively and quantitatively over a wide range of process variables.

Thermomechanical modelling of oblique cutting and experimental validation

International Journal of Machine Tools and Manufacture, 2004
Abstract An analytical approach is used to model oblique cutting process. The material characteristics such as strain rate sensitivity, strain hardening and thermal softening are considered. The chip formation is supposed to occur mainly by shearing within a thin band called primary shear zone.

Study and analysis on cutting forces of oblique cutting of wood

Holz als Roh- und Werkstoff, 1996
The objective of the experiments in this paper is to find out the relationship between cutting forces and oblique angles of cutting edge. The experiment consists of 90°−0° and 0°−90° oblique cutting situations. Each type of experiment includes two wood species and two kinds of chip thickness.

Study and analysis of cutting forces on oblique cutting of wood

Journal of Northeast Forestry University, 1991
Obilque cutting of wood is an important form of cutting wood. With the developing of woodworking industry, it is widely used in wood machinary processing such as planing, milling, sawing, drilling and so on. This paper takes oblique planing and helix milling of wood as examples.

Analysis of Oblique Cutting with Controlled Contact Tools

CIRP Annals, 1986
Starting with an expression which was derived for orthogonal cutting with controlled contact tools and using a recently derived model of the oblique cutting process, a generalised relation between the normal shear plane angle, f nr , and the controlled contact length, f c , applicable to oblique cutting with controlled contact tools in inferred.

The edge force components in oblique cutting

International Journal of Machine Tools and Manufacture, 1990
Abstract It is shown that in an oblique cutting operation two of the edge force components can be derived on the basis of the hypotheses: (a) that there exists an equivalent orthogonal cutting operation which is such that the depth of the layer of workpiece material which is extruded below the cutting edge in oblique cutting, h , is equal to that ...

Estimation of rake temperatures in free oblique cutting

International Journal of Machine Tool Design and Research, 1986
Abstract A model for analysing temperatures in free oblique cutting with sharp cutting tools is developed by utilising a recent solution for temperature distributions on a rectangular heat source moving obliquely on a semi-infinite conducting medium.

Explicit Finite Element Simulation of Oblique Cutting Process

Key Engineering Materials, 2010
An explicit dynamic model of oblique cutting is presented. The explicit solid elements with one-point integration Lagrange algorithm were adopted, and elastic viscoplastic with thermal effect material model was used in simulation. The automatic surface to surface tiebreak contact type was employed to simulate the chip separation from workpiece.
