Infeasibility Cutting Plane for Unit Commitment Problem
CSEE Journal of Power and Energy SystemsThis paper introduces a new type of cutting plane for the unit commitment (UC) problem, namely “infeasibility cutting plane”. The infeasibility cutting plane refers to a type of logic constraint that eliminates the combination of integer ...

Cutting Force Prediction in Drilling of Titanium Alloy
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2012 Cutting force in drilling of Ti-6Al-4V is studied with simulation based on a predictive model. In the force model, three-dimensional chip flow is made by piling up the orthogonal cuttings in the planes containing the cutting velocities and the chip flow ...

Cutting Planes in Combinatorics
European Journal of Combinatorics, 1985 The author uses two combinatorial problems: packing diamonds into a Chinese checkerboard nd Deza's proof of a conjecture of Erdős and Lovàsz [\textit{M. Deza}, J. Comb. Theory, Ser. B, 16, 166-167 (1974; Zbl 0263.05007)] to illustrate how Gomory's cutting plane method for solving integer linear programming problems can be used to solve combinatorial ...

The Number of Plane Corner Cuts
Advances in Applied Mathematics, 1999 An \(n\)-element subset \(\lambda\) of \(\mathbb{N}^2\) which is cut off a line is called a (plane) corner cut of size \(n\). Let be \({\mathbb{N}^2\choose n}_{ \text{cut}}\) the set of corner cuts of size \(n\). [See \textit{S. Onn} and \textit{B. Sturmfels}, ibid., 29-48 (1999; above).] The authors give a generating for the number \(\#{\mathbb{N}^2 ...

An Innovative Experimental Study of Corner Radius Effect on Cutting Forces [PDF]
, 2014 The cutting forces are often modelled using edge discretisation methodology. In finish turning, due to the smaller corner radii, the use of a local cutting force model identified from orthogonal cutting tests poses a significant challenge. In this paper,
