In this paper, a neural network based system for ‘on-line’ estimation of tool wear in turning operations is introduced. The system monitors the cutting force components and extracts the tool wear information from the changes occurring over the cutting process. A hierarchical structure using multilayered feedforward static and dynamic neural networks is used as a specialized subsystem, for each wear component to be monitored. These subsystems share information about the tool wear components they are monitoring and their error in estimating the cutting force components is used to update the dynamic neural networks. The adaptability property of neural networks ensures that changes in machining parameters can be accommodated. Simulation studies are undertaken using experimental data available from manufacturing literature. The results are promising and show good estimation ability.

Cutting tools suffer severe abrasive friction and wear in high speed milling of graphite. Cutting forces were measured and analyzed using time-frequency analysis method to reveal the correlation between cutting force variations and tool wear evolution. The static and dynamic force components increased prominently with tool wear. The cutting force Fy was found the most sensitive to the tool wear evolution. The waveform of cutting force became periodic and irregular with the increase of tool wear. Good correlation was found between the first force harmonic and tool wear.

Process Detection

The development of flexible automation in the manufacturing industry is concerned with production activities performed by unmanned machining systems. A major topic relevant to metal-cutting operations is monitoring tool wear, which affects process efficiency and product quality, and implementing automatic tool replacements. In this paper, the measurement of the cutting force components has been found to provide a method for an in-process detection of tool wear. Cutting force components are divided into static and dynamic components in this paper. The static components of cutting force have been used to detect flank wear and the dynamic components of cutting force have been analyzed to detect crater wear. To eliminate the influence of variations in cutting conditions, tools, and workpiece materials, the relationships between normalized cutting forces and cutting conditions are established. According to the proposed method, the static and dynamic force components could provide the effective means to detect flank and crater wear for varying cutting conditions in turning operation.

An orthogonal test was carried out so as to analyze the cutting force in high speed rough milling with ball-end cutting tools. The wave form of the cutting force components was analyzed. The range analysis was performed to investigate the effect of cutting parameters on the cutting force. The analysis results show that the depth of cut and feed rate have the most significant effect on the resultant force. An empirical equation to describe the resultant cutting force was developed.

Processing Of Measurement Results

The article deals with the experimental investigation of cutting conditions from the view of force load during machining high alloyed tool steel EŠ 419556 (standard by Škoda a.s. Pilsen, based on DIN 1.2326) at high speed milling. The aim of presented research is investigation of the most favourable contact and cutting conditions to minimize the power load of the cutting edge. Processing of measurement results within presented investigation was focused only on the components of cutting force FC (tangent) and FCN (normal) that adequately characterize the cutting process. The experiments were also carried out at cutting depth (ap) changing during high speed milling. The obtained results are presented in the paper by means of graphs that clearly show the behaviour of cutting force components at given conditions.

Cutting Speeds

An original experimental device is used to reproduce conditions of orthogonal cutting for a wide range of cutting speeds (from 15 to about 100 m/s) (Sutter et al.). Improvement of the initial device (Sutter et al.) makes it possible to record both values of normal and tangential forces in orthogonal cutting. An analysis of the tool–chip friction is then possible for a large range of cutting speeds. The evolution of cutting force components as well as the evolution of the friction coefficient are presented and analyzed. In addition, the process of chip formation during high speed machining is illustrated by photographic recording with a high speed camera.

There is a difference in machining by the cutting tool with defined geometry and undefined geometry. That is one of the reasons of implementation of hard turning into the machining process. In current manufacturing processes is hard turning many times used as a fine finish operation. It has many advantages – machining by single point cutting tool, high productivity, flexibility, ability to produce parts with complex shapes at one clamping. Very important is to solve machined surface quality. There is a possibility to use wiper geometry in hard turning process to achieve 3 – 4 times lower surface roughness values. Cutting parameters influence cutting process as well as cutting tool geometry. It is necessary to take into consideration cutting force components as well. Issue of the use of wiper geometry has been still insufficiently researched.
