Real time tool condition monitoring has great significance in modern manufacturing processes. In order to prevent possible damages to the workpiece or the machine tool, reliable monitoring techniques are required to provide fast response to the unexpected tool failure. Milling is one of the most fundamental machining operations. During the milling process, the current of feed motor is weakly re...

Obtaining the complete wear state of milling cutter during processing can help predict tool life and avoid impact breakage. A cylindrical model collection is proposed, which uses collected partial pictures side edge to construct a panoramic picture wear. After evaluating splicing accuracy, fully convolutional neural network (FCN) segmentation algorithm VGG16 structure used segment panorama end ...

A CrN/AlCrN coating was prepared on a carbide substrate and PCB milling cutter by the cathodic arc ion plating technique. The organization, mechanical tribological properties of were studied. performance coated cutters investigated tests. results show that surface is smooth dense without obvious defects. has high hardness, low roughness good bonding strength, presenting excellent properties. sh...

The article presents a method of experimental research and created stand with metrological equip-ment that allows to simulate the complex process milling asphalt concrete samples by force coordinate closure. As result research, regression equations describing parame-ters samples, were obtained. It is established during transition from power (elastic) closure technological system rigid (coordina...

Disc cutter is Full face rock tunnel boring machine (TBM) important rock breaking tool, cutting heat generation has an important influence on cutter life, disc cutter cutting temperature characteristic research be imperative. Based on heat conduction theory to establish disc cutter cutting temperature heat conduction model, and derive its solution; analyze influence on disc cutter cutting tempe...

This paper presents the suitable depth of cut, spindle speed and feed rate that will be chosen during machining. If thus parameters are not considered, this can provoke abnormal tool behavior such as chatter. Chatter will limit the tool life which only can be use for just a few times. To predict the chatter occurs, the parameters will be use are spindle speed, depth of cut and feed rate. CNC ma...
