Determining the force formulas while orthogonal shaped turning by tools with convex radial cutting edge [PDF]

E3S Web of Conferences, 2023
Orthogonal shaped turning is a non-free cutting process, because the main geometric and force parameters are variable while radial infeed of a tool: side cutting edge angle (SCEA), width and thickness of cut, rake angle and flank angle etc..

Effect of preharvest conditions on cut-flower quality

Frontiers in Plant Science, 2023
The cut flower industry has a global reach as flowers are often produced in countries around the equator and transported by plane or ship (reefer) mostly to the global north. Vase-life issues are often regarded as linked to only postharvest conditions while cultivation factors are just as important. Here, we review the main causes for quality reduction

Effect of Machining Conditions on Temperature and Vickers Microhardness of Chips during Planing

Metals, 2022
For the machining of long and narrow surfaces and when processing multiple pieces, planing technology is used, the productivity of which can be higher than that of milling, although it is relatively slow machining. The article aims to study the degree of

An experimental investigation of chatter effects on tool life [PDF]

, 2009
Tool wear is one of the most important considerations in machining operations as it affects surface quality and integrity, productivity and cost. The most commonly used model for tool life analysis is the one proposed by F.W.
