An Indicator Based on Spatial Coordinate Information for Assessing the Capability for Dynamic Machining Performance...

Area of Science:

• Manufacturing Engineering
• Metrology
• Mechanical Engineering

Background:

• Touch-trigger on-machine probes are crucial for ensuring machining quality in manufacturing, particularly in five-axis flank milling.
• Conventional quality assessment using deviation is insufficient for flank milling due to its unique machining characteristics.
• A more comprehensive indicator is needed to evaluate dynamic machining performance accurately.

Purpose of the Study:

• To introduce the error mutual moment as a novel indicator for assessing machine tool dynamic performance in flank milling.
• To validate the superiority of the error mutual moment over traditional deviation methods.
• To explore the potential of the error mutual moment as a quality assessment sensor.

Main Methods:

• Utilizing spatial coordinate data from touch-trigger on-machine probes.
• Developing the error mutual moment indicator, considering flank milling error distribution characteristics.
• Conducting experimental validation comparing error mutual moment with deviation.

Main Results:

• The error mutual moment demonstrates more significant discrepancies than deviation in assessing dynamic machining performance.
• Experimental results validate the effectiveness of the error mutual moment.
• The proposed indicator offers a more nuanced evaluation of machining capabilities.

Conclusions:

• The error mutual moment is a more effective indicator for assessing dynamic machining performance in flank milling.
• This new metric has the potential to be integrated as a quality assessment sensor in manufacturing.
• Adopting the error mutual moment can lead to enhanced machining quality control.
