Abstract
This article deals with the study of the effect of cross section of the cut layer of material and its influence on the specific cutting resistance. Measurement and evaluation were carried out using two machined materials, according to the designation W.Nr. carbon steel 1.1191, which is a reference material for the steel grade and refractory nickel alloy 2.4856. For the purpose of the experiment, longitudinal turning technology with two interchangeable CNMG 120408 SM and CNMX 1204A2 – SM cutting inserts was chosen. According to the recommended index insert values, two different types of cutting conditions were chosen for each material so that the cross section of the chip remained the same during machining. For each material, the cutting speed was constant and the feed rate and cutting depth were changed. The main goal of the experimental work was comparison of the specific cutting resistance in dependence on different cross section of the removed layer of material. On the basis of measuring of cutting forces by dynamometer Kistler the resulting cutting force was determined and the size of the specific cutting resistance was calculated.
Highlights
Machining of the material is a very complex dynamic process in which the cutting tool acts as a tool for separating the chip material from the surface of the machined material
The article was focused on the cross sectional area of the cut layer of material and its influence on the specific cutting resistance during turning of steel 1.1191 and alloy 2.4856
The cutting forces were measured during the machining process and the subsequent evaluation of the measured data
Summary
Machining of the material is a very complex dynamic process in which the cutting tool acts as a tool for separating the chip material from the surface of the machined material. The mechanism of chip formation and the action of the cutting edge on the machined material causes a state of tension in the material This process is accompanied by plastic and elastic deformations and force ratios. The power ratios accompanying the cutting process can be decomposed into a chip force acting perpendicular to the tool face and the frictional force acting on the contact surface of the cut-off material. For the productivity of high-speed lathes, it is important to reduce the occurrence of self-excited vibrations, known as vibration If this fails and vibrations can cause a large dynamic load that damages the machine spindle, the cutting tool, the workpiece, or leaves poor surface quality. The article investigates the effects of cutting parameters on the integrity of the surface during machining
