General Cutting Load Model for Workload Simulation in Spindle Reliability Test

As the key functional component of the machine tool, the reliability test of the spindle is necessary to verify the reliability of the machine tool. In the reliability test, the cutting load model is the guideline of workload simulation and is the prerequisite to ensure the accuracy and effectiveness of the long-term experiment. However, the existing load models usually aim at the specific cutting force at the tool-tip, thereby ignoring the versatility, maneuverability, and accuracy of the load model when applied in the spindle reliability test. In this study, a general cutting load model for the machine tool spindle is established in a form of radial-axial-torque decomposition, and the radial force is simplified as non-rotating status for the maneuverability of conducting a load simulation. The difference between rotating and non-rotating radial force on the reliability calculation is also discussed and corrected using bearing fatigue analysis. A spindle reliability test platform with radial force, axial force, and torque simulation is developed according to the cutting load model, while the loading spectrum is compiled for conducting the spindle reliability test. This research is of great engineering value for the designing of the spindle reliability test.

“…For each TWE, the tool is divided into discrete axial elements along the tool axis. TWE information is described in ECS with the start immersion angle st k  and exit immersion angle ex k  of the cutting flutes at axial height zk along the tool axis for the discrete axial element k, as shown in Figure 2 [22] . The TWE information throughout the five-axis tool path is obtained from the virtual machining software MACHpro TM [23] .…”

Five-axis ball-end milling has been used extensively in the manufacturing of parts with sculptured surfaces. This paper presents the general cutting dynamics model of ball-end milling process for machine tools with different five-axis configurations. The structural dynamics of both the tool and workpiece are considered for the prediction of chatter stability at each tool location along the tool path. The effects of tool-workpiece engagement (TWE) and tool axis orientation are included in the model. By sweeping the spindle speeds, the chatter-free spindle speeds are selected followed by the prediction of forced vibrations in five-axis milling of thin-walled, flexible parts. The proposed model has been experimentally illustrated to predict the cutting stability and forced vibration on a table-tilting five-axis CNC machine tool.
