In this paper, an enhanced mathematical model is presented for the prediction of cutting force system in ball end milling of sculptured surfaces. This force model is also used as the basis for off-line feed rate scheduling along the tool path in order to decrease the cycle time in sculptured surface machining. As an alternative for setting a constant feed rate all along the tool path in rough m...

The machining of fibre reinforced composites is an important activity for optimal application of these advanced materials into engineering fields. During machining, any excessive cutting force has to be avoided in order to prevent any product reject in the last stages of production cycle. Therefore, the ability to predict the cutting forces is essential to select the process parameters necessar...

This paper presents a novel approach that automatically generates interference-free tool path for five-axis flank milling of ruled surface. A boundary curve of the machined surface is subdivided into curve segments. Each segment works as a guide curve in the design method for developable Bézier surface that controls a developable patch for approximating the surface with available degrees of fre...

As any cutting process problem in machining may have some unique characteristics, it may be difficult to select a suitable optimization technique that provide acceptable and improved cutting conditions. This paper discusses the non-conventional optimization approaches for optimizing the cutting parameters in various machining processes such as turning, drilling and milling operations. Based on ...

Thread milling is increasingly used in engineering manufacturing because of its advantages, but there must be some error the thread due to machining principle. In response this problem, paper discussed causes and established model for full process milling. Firstly, geometric developed based on parametric definitions cutter tooth surface, tool-path. Then, motion characteristics penetration retra...

In this study, ultrasonic assisted machining (UAM) technique is applied in side-surface milling experiment for glass-ceramic workpiece material. The tungsten carbide cutting-tool with diamond coating is used in conjunction with two kinds of cooling/lubrication mediums such as water-soluble (WS) cutting fluid and minimum quantity lubricant (MQL). Full factorial process parameter combinations on ...

This paper presents the main characteristics of the 3axis milling machine retrofitted with the Linux-based CNC open architecture control system. It is developed on the basis of a technologically outdated industrial planing machine, which was redesigned for the purpose of the technological project “Intelligent Monitoring of a Machine Tool Main Spindle”. The new machine is intended to be used for...

Pamali, Abhinand P. Using Clothoidal Spirals to Generate Smooth Tool Paths For High Speed Machining. (Under the direction of Dr. Yuan-Shin Lee.) We present a new and innovative method to generate Contour Parallel tool paths using Clothoidal spirals for 2.5D pocket milling. The tool paths generated by the proposed method are more suitable for High Speed Machining compared to the traditional tool...
