“…However, this method selected a circle on a workpiece as the research object in the experiment, and there were few data points selected, which were not enough to reflect the machining error information for the whole workpiece surface. Song et al [10] used an error compensation method, which combined the mirror compensation and Taylor unfolding compensation methods, that could compensate for the trajectory error of the continuous trajectory of a tool by only modifying the G codes.…”

To reduce the errors caused by the overall compliance of the system and the machine tool wear during the machining process for curved workpieces, and to improve the machining accuracies of curved workpieces, a machining error compensation method using a compliance error model to reconstruct the surface was adopted. During a process involving multiple cuts, on-machine measurement (OMM) was achieved by replacing the cutting tool with a touch probe. After the last semi-finishing cut, the error values were measured and compensated for using a compliance error model that predicted the change in the overall compliance of the system and estimated the error at the finishing cut depth based on the measured machining error at the previous cut depth. Finally, the machining errors before and after compensation of formula and free-form surface workpieces were verified experimentally. For the formula surface workpiece, the maximum value of the machining error was reduced from 0.057 mm to 0.0163 mm, and the average absolute value of the machining error was reduced from 0.047 mm to 0.0032 mm after compensation when using the method based on a compliance error model reconstructed surface. For the free-form surface workpiece, the maximum value of the machining error was reduced from 0.0586 mm to 0.0166 mm, and the average absolute value of the machining error was reduced from 0.0483 mm to 0.0057 mm after compensation using the compliance error model reconstructed surface method. It was verified that this method could effectively reduce machining errors and improve the machining accuracy of machine tools. This method can be used to predict and compensate for machining errors at different cut depths, which is of great research significance for machining various types of curved workpieces.

“…Nowadays, the use of machining concepts such as high speed cutting (HSC) in five simultaneous axes, in addition to hard milling (HM) [13][14][15][16][17], is becoming common. These concepts could be introduced in the production chain due to the technological development of machines, cutting tools and computer-aided manufacturing (CAM) systems [18][19][20][21][22].…”

CNC milling of curved surfaces is a common task in the manufacture of molds and dies of products used in various industrial sectors. Notably, in recent years, the use of hard milling has helped manufacturers to obtain these parts with shorter lead times, since the part is machined in a single setup without the problems caused by part distortions from the tempering process. In this work, cylindrical surfaces were machined in AISI H13 steel tempered and annealed to 52 HRC using hard milling and high speed milling concepts in the finishing stage. The cutting tool was feed along either upward ramping or downward ramping directions, and the quality of the texture of the obtained surfaces was evaluated as well as the wear of the ball nose cutter. The results showed that the surface is deteriorated when milling is performed in the downward direction (surface roughness equal to 6.93 μm) compared with the upward direction (2.17 μm). Also, vibration marks are present on the machined surface in the downward direction. In addition, surface roughness is worsened when the tool performs the cut primarily at regions away from the center of the tip of the ball nose cutter. On the other hand, the surface roughness is worsened when cutting with regions near the center of the tip of the ball nose cutter when milling in the upward direction. It was noticed that flank wear in both upward and downward directions was low (less than 10 μm), and micro-chipping was observed in the cutting edges.

“…Lower DOC also causes material additament more uniform, therefore there is often no need for semi-finishing, which will decrease machining time even more. However, fast feed rate demands fast enough control system, otherwise pauses to read some lines of NC program in advance will be needed [10], [11], [12], [13]. The aim of the experiment is to determine surface quality after HFM and if finishing is necessary in all cases after this process.…”

Many industrial corporations are trying to increase productivity. They were made many types of research focused on cost-effective productivity increasing. Researchers and engineers were created new machining strategies and advanced processes, which could be enhanced by modified geometry, advanced coatings and new cutting materials. One of the costeffective methods to increase productivity is High Feed Machining (HFM). This method does not require any special equipment, such as high-speed spindle. Moreover, it does not require any special conditions neither. Due to the fast rapid traverse of many modern machine tools, High Feed Machining can be performed on most of them. This article compares machining of the reference steel materials -C45 by conventional milling and High Feed Machining. The experiment is based on the creating of some simple shapes, such as vertical and horizontal surfaces, notches, cylinders, etc. There were measured several surface roughness parameters. Results of the experiment could be applied to determine what advantages High Feed Machining brings and when it is advantageous.
