Abstract:
Recently, carbide cutter combs have become widespread in mechanical engineering. They are both monolithic and with mechanical fastening of special non-regrinding plastics. Working with a cutting speed of 100… 300 m / h, they increase productivity by reducing the number of teeth compared to cutters from the high-speed capital. Constructional design features of shank-type multiple thread cutters with mechanical mounting of hardmetal disposable tips are examined. Mounting parameters for disposable tips in instrument body frame, limitations in the values of face and tool back wedge angles, as a re

Abstract:
Accurate profiling of thread-milling cutters is one of the main prerequisites of high-precision internal thread production. Despite the accuracy of analytical methods, their complexity in most instances makes practical application an issue. The current research addresses a graphical profiling method, the Tangent Circles Method, introduced by the authors for the facilitation of thread-milling tool geometric design. Several thread-milling cutters were designed employing this method, and their working surface profiles were compared with those obtained analytically. The comparison showed a good ma

The inclination angle of cutting inserts of thread cutters should be adjustable to provide the required geometry when machining threads. In serial production, this adjustment is realized by changing the carbide shims. In the present paper, the analysis of relationships between geometric parameters and positioning accuracy errors for thread cutters with inserts is presented.

Abstract:
Complex surfaces such as helical ones are commonly used in machinery. Such surfaces can be obtained by various machining processes, one of these processes being thread whirling. The influence of machining conditions needs to be better understood to develop a more precise prediction of the specific resulting errors involved in thread whirling. This paper firstly presents the theoretical conditions which generate micro-deviations on whirled surfaces.

However, intensive efforts in the design have made it possible to produce cutters with little variation of chamfering amount for a wide range of tooth numbers.

Rock/bit interaction models are currently verified with a single cutter experiment and the utilization of multi-axis load cells. This paper aims to demonstrate an innovative method that experimentally validates the embedded cutter sensing on a laboratory scaled-drill bit to measure the forces acting on a single cutter. A unique two-cutter drill bit design allows the integration of a sensor measuring the applied force on a cutter while drilling. A fully instrumented mini-rig is a key criterion to recreate the drilling e

Abstract:
In this study we present a new general representation for describing a milling cutter and an internal data structure that systematically stores the cutting edge segment properties of the milling cutter. The intention of this effort is to enable commercial milling simulation software packages to communicate and store complicated cutter information, and thus enable them to include improved models developed in academic research. Examples with various milling cutters are given, and the versatility of the structures is demonstrated by using two different cutting force models with three different mi

Abstract:
Abstract The continuous push for faster and longer bit runs in heavily directional, motor-oriented drilling applications requires Polycrystalline Diamond Compacts (PDC) cutters to better resist impact damage and abrasive wear while providing improved drilling performance. Moreover, drilling longer sections with interbedded lithologies requires PDC cutters to possess both high abrasion resistance and durability to resist dulling from the varied lithologies and overcome drilling dysfunctions inherent to such sections. This work will present optimized PDC cutters that enabled improved drilling pe

Abstract:
Polycrystalline Diamond Compact (PDC) cutters, as the most commonly used inserts for rock cutting/drilling processes, are drawing increased attentions in manufacturing and petroleum engineering driven by the necessity to elevate cutter and process performance. The knowledge of the force response of single PDC cutters under various cutting conditions is an essential prerequisite for achieving this goal. In this paper, an analytical model is derived by extending Nishimatsu’s two-dimensional orthogonal cutting theory for rock cutting to the three-dimensional quasi-orthogonal case. A rock turning

Abstract:
Climate resilience is the ability to anticipate, prepare for, and respond to hazardous events, trends, or disturbances related to climate (C2ES, 2022). Mitigation focuses on reducing the human impacts contributing to climate change (Burton, 2007, cited in Rousell &amp; Cutter-Mackenzie-Knowles, 2020). Adaptation is about increasing people’s adaptive capacity, reducing the vulnerability of communities and managing risks (Anderson, 2012). Anderson further defines adaptation as not just being able to adapt from one stable climate to another but having the skills to adapt to uncertainty and make i

Abstract:
While we are exposed to the physical effects of natural hazard processes, certain groups within a community often bear a disproportionate share of the negative consequences when a disaster strikes. This study addresses questions of why some places and population groups in Canada are more vulnerable to natural hazard processes than others, who is most likely to bear the greatest burden of risk within a given community or region, and what are the underlying factors that disproportionally affect the capacities of individuals and groups to withstand, cope with, and recover from the impacts and dow
