Selection of cutting modes for basalt plastics

Technology of Metals, 2022
The analysis of the prospects for the use of basalt plastics in various industries has been carried out. The types of cutting tools used for machining PCM based on basalt fiber were studied. The results of mechanical processing of samples of basalt plastics by an end mill made of high-speed steel R6AM5, using a machine with numerical control in various

Virtual modes in AT-cut resonators

Proceedings of the 2002 IEEE International Frequency Control Symposium and PDA Exhibition (Cat. No.02CH37234), 2003
Although studied for more than 40 years, drive-level dependent modes apparently remain an unresolved problem in the design and manufacture of high-performance AT-cut quartz crystal resonators. Our intention is to give a clear presentation of this phenomenon and what is known about these modes.

Diathermocoagulation in Cutting Mode and Large Flap Dissection

Plastic and Reconstructive Surgery, 2011
The aim of this study was to determine the overall complication rate associated with the use of diathermocoagulation in cutting mode for flap dissection.Because of the high rate of complications generally associated with abdominoplasty, a large flap, abdominoplasty, or abdominal dermolipectomy model was chosen.

Ductile Mode Cutting of Glass

2019
Recently, the industrial application of glass has increased enormously because of its excellent and unique mechanical, physical, chemical and optical properties. However, machining of glass is still a major problem for the manufacturing industry since it is very brittle and high hardness.

Optimal Stochastic Control of the Cutting Modes on the Grinders

IFAC Proceedings Volumes, 1986
Abstract The problems of control algorithm synthesis of grinding technological process are discussed here, with stochastic properties of control object and technological limitations being taken into account. This task is effected by the optimization method "in average" using law distribution characteristics of control object parameters and ...

Ductile Mode Cutting Mechanism

2019
In this chapter, ductile mode cutting mechanism of brittle material is analysed theoretically and systematically. The coexisting crack propagation and dislocation extension in the chip formation zone are examined based on an analysis of cutting geometry and forces in the cutting zone, both on Taylor’s dislocation hardening theory and strain gradient ...

Ductile Mode Cutting of Silicon

2019
In wafer fabrication, most machining processes such as slicing, edge grinding, finishing, lapping, polishing, back thinning and dicing, are based on grinding or/and abrasive process, which always generate micro cracks and subsurface damage. In this chapter, theoretical analysis on ductile mode cutting of silicon wafer shows that machined silicon ...

Suppression of the B-mode in SC-Cuts

2007 IEEE International Frequency Control Symposium Joint with the 21st European Frequency and Time Forum, 2007
We have found it possible to suppress the B-mode of fundamental mode SC-cuts over wide temperature ranges by imbedding the B-mode in a cluster of C-mode anharmonics with choice of diopter. This work presents a variety of theoretical results and experimental data supporting the approach.

Thermally Assisted Ductile Mode Cutting

2019
The growing necessity for advanced manufacturing technologies brings forth initiatives to incorporate thermal effects in micromachining of difficult-to-machine brittle material. While conventional heating methods exist in the macroform and are infeasible for micro-cutting applications, the fundamental concepts of heating are miniaturized to enable ...
