Abstract

This paper presents a methodology and algorithms of admissible tool orientation control for gouging avoidance in 5-axis machining. A method is proposed to find the admissible tool orientation by considering both local and global surface shapes. A filleted endmill is used in this study for 5-axis machining. Based on the evaluation of local surface shape, a geometry analysis method is developed to first find a feasible tool orientation for gouging avoidance along two orthogonal cutting places. Adjacent geometry is then taken into consideration for detecting possible rear gouging. A localization algorithm is developed for filleted endmills to identify potential rear gouging area. Both the circular approximation, and the detailed gouging checking methods are proposed for rear gouging correction. The techniques presented in this paper can be used to eliminate errors of tool paths as they are generated. Unlike the traditional graphical verification and user-interactive correction of tool path generation, the proposed methodology can be used to automate the planning and programming of cutter path generation for 5-axis machining.

Least variation in tool orientation control for 5-axis CNC machining
2022, Computer Aided Geometric Design
We address the problem of minimizing the variation of the tool axis orientation of a 5-axis CNC machine equipped with a ball-end cutter that is designed to maintain a constant cutting speed, which is ensured by a fixed angle ψ between the tool axis $a (t)$ and the workpiece surface normal $n (t)$ at each point of contact as the cutter moves along a specified toolpath. The configuration can be mathematically translated into a pair of curves $a (t)$ and $n (t)$ on the unit sphere with constant parametric distance ψ, and the least variation of the tool axis orientation is achieved when the overall length of the curve $a (t)$ is minimized under certain auxiliary boundary conditions. Using the calculus of variation we show that the solution $a (t)$ consists of arcs of great circles and offset curves of $n (t)$ on the unit sphere. A numerical approximation scheme based on Euler's method of finite differences is also provided.
Interference and grinding characteristics in ultra-precision grinding of thin-walled complex structural component using a ball-end grinding wheel
2021, Chinese Journal of Aeronautics
As for ultra-precision grinding of difficult-to-process thin-walled complex components with ball-end grinding wheels, interference is easy to occur. According to screw theory and grinding kinematics, a mathematical model is established to investigate the interference and grinding characteristics of the ball-end wheel. The relationship between grinding wheel inclination angle, C axis rotation angle, grinding position angle and grinding wheel wear are analyzed. As the grinding wheel inclination angle increases, the C axis rotatable range decreases and the grinding position angle increases. The grinding position angle and wheel radius wear show a negative correlation with the C axis rotation angle. Therefore, a trajectory planning criteria for increasing grinding speed as much as possible under the premise of avoiding interference is proposed to design the grinding trajectory. Then grinding point distribution on the ball-end wheel is calculated, and the grinding characteristics, grinding speed and maximum undeformed chip thickness, are investigated. Finally, a complex structural component can be ground without interference, and surface roughness and profile accuracy are improved to 40.2 nm and 0.399 μm, compared with 556 nm and 3.427 μm before ultra-precision grinding. The mathematical model can provide theoretical guidance for the analysis of interference and grinding characteristics in complex components grinding to improve its grinding quality.
A Tracking-Based Numerical Algorithm for Efficiently Constructing the Feasible Space of Tool Axis of a Conical Ball-End Cutter in Five-Axis Machining
2019, CAD Computer Aided Design
To meet the high requirement on cutter stiffness in five-axis machining of complex parts with deep channels, such as an aero-engine blisk, conical ball-end cutter is preferred over the traditional cylindrical cutter as the former can increase the stiffness ten folds or more over the latter of a same size. However, because the shank of conical ball-end cutter is a cone instead of a cylinder, when calculating the feasible space of tool axis (FSTA) for any given center of the ball-end, the line-visibility, which is critically utilized in the case of cylindrical ball-end cutter, is no longer applicable. Currently in practice, the calculation of FSTA for the conical ball-end cutter has to resort to the simplest brute-force approach of checking for collision for every sampled tool axis. This process of exhaustive collision checking is extremely time-consuming and lacks accuracy, as there are typically thousands of center points of ball-end on a five-axis tool path, and for each of them there can be again thousands of sampled tool axes to check for collision, which is itself a very time-consuming task. In this paper, we propose a tracking-based numerical algorithm for constructing FSTA of the conical ball-end cutter amid an obstacle environment defined by freeform surfaces. Our algorithm avoids the time-consuming collision checking by directly tracing out the characteristic curves on the boundary surfaces of obstacles. As a result, it not only tremendously reduces the computing time by only searching around the boundary of FSTA, but also substantially improves the accuracy of the final constructed FSTA as the step size of tracing can be set sufficiently small without increasing much on the computing time. Simulation tests of the proposed algorithm are also reported to validate its time efficiency and accuracy.
Region based five-axis tool path generation for freeform surface machining via image representation
2019, Robotics and Computer-Integrated Manufacturing
This paper inaugurates a brand new five-axis tool path generation method for freeform surface machining, which is solely based on digital image processing. By utilizing image representation, a freeform surface can be digitized into a uniform grayscale image. With this novel representation, we come up with a region based five-axis tool path scheme with remarkably enhanced utility towards freeform surface machining process. The image representation possesses sufficient geometric data for us to evaluate the surface normal distribution and split the surface area accordingly via image processing algorithms. Since each partitioned region contains a limited surface inclination range, one rotary axis is locked with a certain angle during the processing of this region. In addition, by further exploiting the potential of the image representation, the cutter contact (CC) curves are extracted purely from the image of each partitioned region. Preliminary results show that this method is more than adequate for the tool path computation. The computed tool path outperforms the benchmarks by reducing the machining time for as much as 40%, as verified in the physical cutting test.
Vibration monitoring of ball nose end mill tool during milling of sculptured surfaces using MUP6050 sensor
2019, Materials Today: Proceedings
Optimization of parameters like tool path, cutter geometry, feed rate optimization, tool path and feed rate integration for sculptured surface machining has been an active research zone. The next step is to investigate the effect of vibration in ball end mill tool during milling machining of the sculptured surface. Milling machining process which is characterized by interrupted cutting, the problems of vibration occur in the machine-tool-work piece fixation device. In this work, experimental measurement of time domain signals amplitude of vibration (Acceleration) using Arduino Uno (microcontroller board) with MPU6050 (MEMS accelerometer) during machining of the surface of a selected sculpture is performed. These signals are then used to calculate the frequency of acquired signals using NI DIAdem software. The study shows the optimum values of different parameters under consideration. Such an analysis can also be helpful in fault diagnosis of CNC milling machine parts of sculptured surfaces. The investigations indication that feed is the most governing factor affecting the surface texture, and the cutting speed is the key factor affecting tool vibrations amplitudes. The results of experimental investigations are in agreement with the mathematical model generated using.
A multi-objective tool-axis optimization algorithm based on covariant field functional
2018, Journal of Manufacturing Systems
In multi-axis machining, sudden change of tool-axis orientation has adverse effects on the machining quality and efficiency. In this paper, we proposed a mathematical framework to generate smooth tool-axis variation even on part surfaces lacking G2 and/or G1 continuities. An integral functional is formulated as the object function to represent the measurement of the rate of tool-axis change. The functional is covariant so that the result is independent of surface parameterization and applicable to non-Euclidean geometry. The minimization of the integral functional ensures minimal fluctuation of tool-axis. Other machining requirements, such as gouging-free, preferred (or greedy) direction, are incorporated into this optimization problem as constraints. The unified optimization problem is solved by a Finite Element Method (FEM) numerical method. The proposed algorithm is implemented in the planar sections of blade rough machining to produce tool path with smooth tool-axis variation. Machining results indicate that the presented algorithm can improve machining quality/efficiency and avoid gouging.
