文摘
- •
An electromechanical model is proposed to reveal the mechanism of feed fluctuation.
- •
The analytical expression of displacement fluctuation is deduced.
- •
Displacement fluctuation increases significantly in the situation of resonance.
- •
Feed fluctuation leads to bright and dark stripes of part.
- •
The mechanism of stripes is the periodic change of scallop height on part surface.
