A reasonable analysis of cutting force in end milling may give much advantage to improvement of productivity and cutting tool life. In order to analyze cutting force, the cutting dynamics was modelled mathematically by using chip load, cutting geometry, and the relationship between cutting forces and the chip load. Specific cutting constants of the cutting dynamics model were obtained by average cutting forces, tool diameter, cutting speed, feed, axial depth, and radial depth of cut. The effects of the cutting conditions on the specific cutting force constants in milling were studied. The model is verified through comparisons of model predicted cutting forces with measured cutting forces obtained from machining experiments.

When materials AL 6061 was machined by the selected condition using the CCGT20404-T Insert Tip, The cutting resistance of three components was obtained from Dynamic strain amplifier of Tool Dynamometer in case of the data which was machined the selected conditions were stored into computer. if investigate the result and analyze them, or in summary, there were obtained the following conclusion. 1) The relation of a cutting speed and a cutting conditions is good at a cutting machinability when the cutting speed is higher. The relation of a cutting depth and a cutting condition is good at machinability when the cutting depth is lower. 2) Experimental results for materials in a cutting condition given in this experiments, cutting depth had a higher effect than the cutting speed and the feed rate. 3) When machining the material (Al 6061) in the present experimental conditions, the most favorable cutting conditions that a cutting power consumption and a cutting speed are small were a cutting speed 290m/min, a cutting depth 0.5mm and a feed rate 0.2mm/rev when using CCGTI 20404-R Insert Tip.

This paper discusses the minimum cutting thickness with a continuous chip in sub-micrometer order precision diamond cutting. An ultra precision cutting model is proposed, in which the tool edge radius and the friction coefficient are the principal factors determining the minimum cutting thickness. The experimental results verify the proposed model and provide various supporting evidence. In order to reduce the minimum cutting thickness a vibration cutting method is applied, and the effects are investigated through a series of experiments under the same conditions as conventional cutting method.

Automatic monitoring of cutting process is one of the most important technologies for increasing the stability and the reliability of unmanned manufacturing system, In this study, basic methods which use the acoustic emission (AE) signals and cutting forces were proposed to monitor flank wear (width of flank wear) quantitatively. First, in order to detect flank wear, it was investigated that the influence of cutting conditions, that is, cutting velocity, feed and depth of cut, on AE signals (AErms) and cutting forces. Futhermore, the relation between flank wear and the measured signals (AErms cutting force) was discussed.

For improvement of productivity and cutting tool life, cutting force in end milling needs to be predicted accurately. In order to analyze cutting force, the cutting dynamics was modelled mathematically by using chip load, cutting geometry, and the relationship between cutting forces and the chip load. Specific cutting force coefficients of the cutting dynamics model were obtained by average cutting forces, tool diameter, cutting speed, feed, axial depth, and radial depth of cut. The effects of the cutting conditions on the specific cutting force constants in milling were studied. The model is verified through comparisons of model predicted cutting forces with measured cutting forces obtained from machining experiments.

In interrupted cutting, the workpiece has a groove that impacts both the cutting tool and the workpiece. Therefore, cutting tool damage occurs rapidly. In this study, I performed interrupted cutting of carbon steel formachine structures (SM20C) using an uncoated carbide tool (SNMG120404, P20), and observed tool damage,cutting chip shape, and the workpiece surface. Results: Under the specific cutting conditions of feed rate = 0.066mm/rev, cutting speed = 120 m/min, and depth of cut = 0.1 mm; and feed rate = 0.105 mm/rev, cutting speed= 120 m/min, and depth of cut = 0.2 mm, the observed tool damage was small. Similar chip shape wasobserved (Expt. No. 1, 3, 7). Workpiece damage was observed (Expt. No. 3, 5, 7, 9). Key Words

In this study the surface roughness characteristics of structure steel were investigated according to cutting conditions. The surface characteristics of rod surface are usually investigated at various cutting conditions such as cutting speed, feed rate and cutting depth of workpieces. Experiments were conducted in a CNC lathe and the surface roughness of workpiece for dry and wet cutting were estimated. Machining was performed with revolutions per minute of 3200rpm, cutting depth of 0.8mm and 1.0mm, and feed rate of 0.15mm/rev, 0.25mm/rev, cutting oil of both wet and dry respectively. As a method of evaluation, piston rod was measured for each cutting.
