Spectrum arguments, parity and persistency

This article shows that introducing the positive comparative relation parity only helps one block so-called “Spectrum Arguments” in order to avoid their unsavoury implications if one specifies parity in a specific way with respect to its persistence. The article illustrates how parity must both admit of persistency and be weakly non-persistent for parity to block Spectrum Arguments, and identifies

Influence of the Workpiece Material Properties on the Cutting Forces

This study focuses on modelling the cutting resistance as a function of the workpiece material properties. Thus, for a workpiece material the cutting resistance may be predicted from the material properties without using any experiments. The cutting resistance may then be used to determine the cutting forces, data which in turn may be used to determine appropriate process parameters and select cut

Machinability of Ductile Single-Phase Materials Used in Accelerator Components - A Study with Focus on Surface Integrity

The focus of this article has been to analyse the machinability, with focus on surface integrity, of oxygen-free copper (OFC) and niobium during turning operations. The results from machining OFC proved that all of the tools that was tested can be used to achieve a surface roughness below Ra = 0.8 µm with the correct cutting data. From the results when machining niobium it showed that only the cem

A Basic Economic Model for Judging Production Development

The described technical-economic model clarifies the influence of different production technological factors on the processing cost of a part. The model represents the fundamental theory for the judging of different types of production development. Various influential factors can be weighted against each other, which leads to different production development scenarios and their effects on the proc
