Material displacement detection method and material displacement detecting device

摘要

PROBLEM TO BE SOLVED: To reduce the labor of a manufacturing test by preventing a reduction in generation of non-conforming articles and a mixture of non-conforming articles and conforming articles when a material is lathe-processed.;SOLUTION: At a reference position of a material B1 when a processor 1 opens a processor chuck 12 to release a post-processed material B1, and a current position of the material B1 during the period from the retreat of the processor chuck 12 with respect to the material B1 to the re-closure of the processor chuck 12, or after the processor 1 closes the processor chuck 12, a feed rod stop signal indicating a stop state of a feed rod 31 when supplying the material B1 to the processor 1 is detected to determine a displacement of the material B1 from the reference position upon whether or not the feed rod stop signal from the reference position reverses at the current position.;COPYRIGHT: (C)2015,JPO&INPIT
