Abstract
A sewing machine includes a feed portion, a detection portion configured to detect ultrasonic waves, a processor and a memory configured to store computer-readable instructions. The computer-readable instructions cause the processor to perform processes that includes identifying a first position based on the ultrasonic waves, calculating a first distance based on the first position, causing the feed portion to feed the work cloth in accordance with first data, identifying a second position based on the ultrasonic waves after the feed portion has fed the work cloth in accordance with the first data, calculating as third distance based on the first distance and the second position, calculating a feed efficiency of the feed portion, correcting a fourth distance to a fifth distance based on the feed efficiency, and causing the feed portion to feed the work cloth in accordance with second data for feeding the work cloth over the fifth distance.
