“…According to the calculation, the volume of the maximum cutting zone on the concave surface was 1.8 times greater than the volume of cuttings on the slope. 10 Accordingly, a novel trajectory planning method for annular cutters was proposed, whose effectiveness in controlling the formation of a cutting zone was also confirmed.…”

This study proposed a novel milling technology assisted by longitudinal-torsional compound ultrasonic vibration to overcome the difficulties in the processing of Ti-alloy heterogeneous surfaces or molding surfaces. Using the ball-end milling cutter as the research object, the geometrical model of the milling cutter edge was established, in which an axial position angle was used as the main parameter. The instantaneous cutting thickness was derived based on the cutter path and the cutting force model of the ball-head milling cutter under the longitudinal-torsional compound vibration condition. Finally, using the longitudinal-torsional synchronous vibration cutter system with a resonant frequency of 35.476 kHz and a longitudinal-to-torsional vibration amplitude ratio of approximately 0.25, the milling characteristics of fixedcurvature Ti-alloy workpieces under the longitudinal-torsional compound ultrasonic vibration condition were examined. Results show that the application of the longitudinal-torsional compound ultrasonic vibration can remarkably reduce the radial force F x but impose almost no effects on the tangential force F y and the axial force F z .

“…Theoretical models for predicting the cutting force and machining error in ball-end milling have been reported [2,3]. Iwabe proposed a ball-end milling cutting model using 3D-CAD [4], and Schulz proposed a geometrical model for describing the cutting process in ball-end milling with a tilt angle [5]. Furthermore, Kim reported a new mathematical model for estimating the deflection of the tool in ball-end milling [6].…”

For a cutting process using a low-rigidity end mill, it is very important to be able to estimate the machining error caused by the deflection of the tool. The purpose of this study is to establish a method for the real-time estimation of the machining error caused by the deflection of the tool at the cutting point of a ball-end mill. The method was verified by comparing the estimated deflection and the machining error when milling an inclined surface. It was concluded that the machining errors in ball-end milling of inclined surfaces can be estimated from the normal force at the moment when the radial direction of the peripheral cutting edge is normal to the feed direction of the tool.

“…Therefore, many researchers have set out to propose cutting models for ball-end milling. Previously, a ball-end milling cutting model using 3D-CAD was reported [2], and a geometrical model for describing the cutting process in ball-end milling with a tilt angle was proposed [3]. Furthermore, a new mathematical model for estimating the deflection of the tool in ball-end milling was also proposed [4].…”

For a cutting process using a low-rigidity end mill, it is very important to be able to estimate the degree of machining error caused by the deflection of the tool. The purpose of this study is to establish a method of estimating, in real time, the machining error caused by the deflection at the cutting point of an end mill. To this end, in this research, a method for estimating the machining error caused by the deflection of the tool used for the ball-end milling of a hemispherical surface was verified by comparing the estimated and measured deflections of the tool. As a result, it was found that the machining errors in ball-end milling could be estimated from the normal force at the moment when the radial direction of the peripheral cutting edge is normal to the feed direction of the tool.
