Productivity gains and minimum environmental impacts is the new challenge faced by enterprises, industries, researchers. Mechanical machining one of widely used techniques in manufacturing. So, it’s important to accurately effectively estimate optimize overall ecological economic footprint. Since, cutting energy cost proportional time, production-costs minimization could be achieved embracing t...

Trochoidal milling is an efficient strategy for the rough machining of difficult-to-cut materials. The true trochoidal toolpath has C2 continuity and avoids sharp changes in engagement angle cutting load, resulting smooth machine tool movement. However, its total length too long, uneven. These factors limit further improvements material removal rate. Based on model, this paper develops ellipse-...

The problem of determining the inputs to the rotary axes of a 5–axis CNC machine is addressed, such that relative variations of orientation between the tool axis and surface normal are minimized subject to the constraint of maintaining a constant cutting speed with a ball-end tool. In the context of an orientable–spindle machine, the results of a prior study are directly applicable to the solut...

This paper presents a comprehensive virtual simulation model for CNC systems. The Virtual CNC (VCNC) has a modular architecture, allowing a real CNC to be prototyped quickly from standard library functions for feed drive models, feedback devices, axis control laws, and trajectory interpolation. Additional CNC modules can easily be prototyped and integrated to the VCNC by the user. Various appli...

Parts with the complex curved surface are commonly used in high-end equipment. The machining quality of parts is important for property With position control main spindle, i.e., C axis, slow tool servo (STS) turning a very promising technique to effectively machine parts. However, restricted by cutting force fluctuation finishing turning. Hence, STS toolpath generation approach constraint propo...
