Simulation of Intermittent Turning Processes

Surface Roughness Control Simulation of Turning Processes

The machining quality on computerized numerically controlled (CNC) machine tools is sensitive to the machining parameters. With modern machine tools, an operator still manually adjusts controlling parameters, such as feed rate and cutting speed. The adjusted values mainly depend on operator experience and knowledge. Standard machining catalogues and commercial cutting condition prediction softw...

Strategy in Generative Planning of Turning Processes

This paper reports on the process and operations planning systcm KOL'ND and the strategies which underlie the decision making processes in the planning of turning operations. A t first, an outline is ziven about the environment for which generative systems like ROUND are being developed. Thc differences between high volume production and job shop production, with respect to flexibility and prod...

Simulation of Cutting Process in Turning

This paper presents simulation of cutting process by turning of polyamide PA 66, the simulation based on approach Arbitrary Lagrangian Eulerian, ALE. Was taken into account a tool knife CNMA from Coromant. The flow stress of the workpiece is modeled as function of strain, strain rate and temperature, so as to reflect its dynamic changes in physical properties. In this way, the influences of dep...

Turning Signal Integrity Simulation Inside Out

So what does it mean to turn signal integrity simulation inside out? Modern simulation has physics-based solvers in the foreground supported by circuit and system simulation rather than the other way around. All electronic design is fundamentally based on Maxwell’s equations, so naturally the most rigorous way to deliver accurate simulation of high-performance systems is to solve those equation...
