From machine‐centered to human‐centered manufacture
International Journal of Human Factors in Manufacturing, 1991AbstractThis article provides a case study analysis of the process of transition from a traditional machine‐centered job‐shop working environment to a human‐centered manufacturing facility at a hardware fabrication plant in South Australia. The origination, design, and implementation of cellular manufacturing is examined, and the consequences of change

SIG Machining Center Renovation
2020The functional prototype of the CNC machine will be created by the reconstruction of the existing SIG CF2 machining center. Including the development of a new single purpose control system based on HW and SW components from OMRON, which results in faster, more efficient and easier to operate and service than the old control method.

Machine capability index evaluation of machining center
Journal of Mechanical Science and Technology, 2013Recently, there has been an increasing need to produce more precise products, with only the smallest deviations from a defined target value. Machine capability is the ability of a machine tool to produce parts within the tolerance interval. Capability indices are a statistical way of describing how well a product is machined compared to defined target ...

How to center deep Boltzmann machines
J. Mach. Learn. Res., 2016Summary: This work analyzes centered Restricted Boltzmann Machines (RBMs) and centered Deep Boltzmann Machines (DBMs), where centering is done by subtracting offset values from visible and hidden variables. We show analytically that (i) centered and normal Boltzmann Machines (BMs) and thus RBMs and DBMs are different parameterizations of the same model

Characterization of CNC machining centers
Journal of Manufacturing Systems, 1991Abstract Characterization of CNC machining centers is a difficult task due to its inherent complexity and diversity. Although many different approaches have been proposed, none singularly serves as a globally accepted test procedure. This paper addresses this important issue by establishing a comprehensive characterization procedure for CNC machining

FEM Analysis in a Machining Center
2002This paper analyses a methodology that may be followed for the practical design of the structural elements that compose a numeric-control machining centre, using a FEM (Finite Element Method) calculations. Detailed calculations are presented in the case of an important part of a machine tool such as the spindle-head holder.
