The Review of Economic Performance and Social Progress 2001: The Longest Decade: Canada in the 1990s [PDF]

In this chapter, Jim Stanford agrees that measures were needed to eliminate the deficit. But he argues that Paul Martin's program spending cuts were larger than necessary and caused real pain in many areas of Canadian life.

Discrete control of cutting processes on numerically-controlled cutting machines

Весці Нацыянальнай акадэміі навук Беларусі: Серыя фізіка-тэхнічных навук, 2016
The problem of numerically-controlled cutting machines efficiency increase by insertion of the kinematics instability in the cutting process is considered. Mathematical models of cutting speed and feed control in the function of path are presented.

Optimization of Cutting Path for Minimizing Workpiece Displacement at the Cutting Point: Changing the Material Removal Process, Feed Direction, and Tool Orientation

, 2013
The vibrations of a workpiece during machining shorten the tool life and deteriorate the surface roughness in cases where the workpieces have a low stiffness (as is the case with artificial hip joints).

Machining strategy development in 5-axis milling operations using process models [PDF]

, 2010
Increased productivity and part quality can be achieved by selecting machining strategies and conditions properly. At one extreme very high speed and feed rate with small depth of cut can be used for high productivity whereas deep cuts accompanied with ...

Vibrations of Flat-End Cutter Entering Workpiece Process: Modeling, Simulations, and Experiments

Shock and Vibration, 2018
During all the machining process, the milling cutter has to enter the workpiece either from the boundary or from the machined/unmachined surface, due to the change of machining sequence/cutter or the variation of cutting depth.

Min Cuts Without Path Packing

, 1999
This report presents research into a fundamentally new approach to finding all pairwise minimum cuts in a network that can utilize optimality conditions other than those characterized by Mengers theorem or the max-flow min-cut theorem. The focus is on vertex degree domination, rather than construction of saturating paths.
