The paper presents a study on the performance of cutter tip for wood milling process. The tests were performed with the tropical wood samples which were milled in the double sided wood planer, the measured micro-geometrical parameters encompassing the linear wear and tooltip radius. The study primarily contributes to developing a far better understanding of the physical nature of cutting tool wear in response with the growing concern of many researchers. Given this basis, it does not only assist the selection of reasonable cutting tool but also enable the detection of the patterns in the cutting tool wear process. In terms of tool wear and bluntness, there has been a number of researches taking account into the physical nature of cutting tools, - providing basis for selection of cutting tools apart from clarification of the current pattern of tool wear and bluntness. The load applied to the cutter during wood milling is the load that changes marks periodically. When starting to work after tool sharpening and finishing, the first stage changes the microscopic geometry - tool run-in process (rapid initial wear), followed by constant conditions of wear before a rapid wear which leads to failure at last. The objective of this study is to determine the influence of the cutting path to the tooltip radius and linear wear of the cutting edge. The paper employs method of least squares and variance analysis in application of the Minitab software to determine regression equations for relation of the tooltip radius and linear wear to the relative cutting length. The ultimate goal is to predict the life of cutting tool when milling tropical wood.

Abstract Although Inconel 718 is an important material for modern aircraft and aerospace, it is a kind material, which is known to have low machinability. Especially, while these types of materials are machined, high cutting temperatures, BUE on cutting tool, high cutting forces and work hardening occur. Therefore, in recent years, instead of producing new cutting tools that can withstand these difficult conditions, cryogenic process, which is a heat treatment method to increase the wear resistance and hardness of the cutting tool, has been applied. In this experimental study, feed force, surface roughness, vibration, cutting tool wear, hardness and abrasive wear values that occurred as a result of milling of Inconel 718 material by means of cryogenically treated and untreated cutting tools were investigated. Three different cutting speeds (35-45-55 m/min) and three different feed rates (0.02-0.03-0.04 mm/tooth) at constant depth of cut (0.2 mm) were used as cutting parameters in the experiments. As a result of the experiments, lower feed forces, surface roughness, vibration and cutting tool wear were obtained with cryogenically treated cutting tools. As the feed rate and cutting speed were increased, it was seen that surface roughness, vibration and feed force values increased. At the end of the experiments, it was established that there was a significant relation between vibration and surface roughness. However, there appeared an inverse proportion between abrasive wear and hardness values. While BUE did not occur during cryogenically treated cutting tools, it was observed that BUE occurred in cutting tools which were not cryogenically treated.

Edge Preparation

Edge preparation is not only the process of grinding proper geometry of cutting edge or removing micro-cracks on cutting edge region, but also a way of improving cutting tool life. In this study, cutting models with different cutting edge radius were set up with FEM software. Medium carbon steel cutting tests were carried out using cutting tools with different edge radius. Cutting tool wear was simulated and measured for comparison. The simulation results show that edge radius has influences on tool wear. Tool cutting behavior is concerned with edge radius. A proper edge radius will improve the tool life. The experimental results show that proper edge preparation could improve tool impact resistance capability and reduce tool wear. The cutting tool life can be prolonged with suitable edge preparation. Edge preparation can improve cutting performance of cutting tool.

Wide Range

Stainless steels with unique corrosion resistance are used in applications with a wide range of fields, especially in the medical, food, and chemical sectors, to maritime and nuclear power plants. The low heat conduction coefficient and the high mechanical properties make the workability of stainless steel materials difficult and cause these materials to be in the class of hard-to-process materials. In this study, suitable cutting tools and cutting parameters were determined by the Taguchi method taking surface roughness and cutting tool wear into milling of Custom 450 martensitic stainless steel. Four different carbide cutting tools, with 40, 80, 120, and 160 m/min cutting speeds and 0.05, 0.1, 0.15, and 0.2 mm/rev feed rates, were selected as cutting parameters for the experiments. Surface roughness values and cutting tool wear amount were determined as a result of the empirical studies. ANOVA was performed to determine the significance levels of the cutting parameters on the measured values. According to ANOVA, while the most effective cutting parameter on surface roughness was the feed rate (% 50.38), the cutting speed (% 81.15) for tool wear was calculated.

Toolpath Generation

A strategy of toolpath generation based on Tool-Zmap geometric model has been proposed to achieve efficient finish machining of mold cavity. Considering cutting tool wear, the finish machining of mold cavity was performed using variable cutting tools of different diameter. Each cutting tool only cuts the corresponding area to avoid identifying machining characteristic and poor rigidity of cutting tool during high speed machining. Finally, the validity of presented strategy was experimentally affirmed by a machining example.

In order to improve cutting tool wear resistance, non-smooth surface was applied on HSS cutting tool and finite element method was used to analyze the wear of non-smooth surface HSS cutting tools. The orthogonal simulation test was established to analyze the influence of parameters on tool wear and the relationship between parameters and tool wear was discussed. Simulation results show that non-smooth surface could significantly improve the wear resistance of cutting tool. The line space has the most influence on cutting tool wear. The ranking of parameter influence on tool wear are line spacing, pit diameter and column spacing. And the lower tool wear usually occurs at points of pit line space which is three times as pit diameter.

This paper presents research on the influence of CAM strategies for wear and durability of milling tools. We used two machining principles in this process. In the first instance was constant point of contact with the tool and machining surface. The second method was changing point of the cutting edge in the milling process. Material of tool was hard alloy and high speed steel for machining steel 40CrMnMo7 and C45. The shape of cutting tool was a “Ball Nose” end mill. A DMU 85 monoBLOCK 5-axis CNC milling machine was used. The cutting tool wear was measured in Zoller Genius 3, universal measuring machine and digital microscope, Dino lite 2. The results show differences of cutting tool wear depending on the milling strategy and material of tool.

The tool-wear of cutting tools has a very strong impact on the product quality as well as efficiency of the machining processes. Despite the nowadays high automation level in machining industry, tool -wear diagnostic that is measured of the machine tool, still prevent complete automation of the entire machining process. Therefore, its in line characterization is crucial. Thus the paper presents developed innovative, robust and reliable direct measuring procedure for measuring spatial cutting tool-wear in-line, with the usage of laser profile sensor. The technique provides possibility for determination of 3D wear profiles, as advantage to currently used 2D subjective techniques (microscopes, etc.). The use of proposed measurement system removes the subjective manual inspection and minimizes the time used for wear easurement. In the manuscript the system is experimentally tested on a case s tudy, with further in-depth performed analyses of spatial cutting tool-wear.

The present work is motivated by the will to improve Finite Element (FE) Modelling of cutting tool wear. As a first step, the characterisation of wear mechanisms and identification of a wear model appear to be fundamental. The key idea of this work consists in using a dedicated tribometer, able to simulate relevant tribological conditions encountered in cutting (pressure, velocity). The tribometer can be used to estimate the evolution of wear versus time for various tribological conditions (pressure, velocity, temperature). Based on this design of experiments, it becomes possible to identify analytically a wear model. As a preliminary study this paper will be focused on the impact of sliding speed at the contact interface between 304L stainless steel and tungsten carbide (WC) coated with titanium nitride (TiN) pin. This experiment enables to observe a modification of wear phenomena between sliding speeds of 60 m/min and 180 m/min. Finally, the impact on macroscopic parameters has been observed.
