In step S2, if the thickness of backing plate changes, the lower dead center M of drill point0Position also change, remember again
Record the lower dead center M0Opposite distance Z of the machine origin in the Z-direction of lathe coordinate system0。
Drilling M in step S3, when drill point carries out PCB drilling, on drill point and aluminium foiliGalvanic circle is contacted and is formed, and
The drilling M on aluminium foil is recorded by the grating rule displacement sensor on latheiOpposite machine origin is in the Z axis side of lathe coordinate system
Upward distance Zi。
In step S4, the processing module and memory module are respectively mounted on computers, and lathe passes through data line or network will
The data Z of record0、ZiIt is sent to processing module.
The present invention has the advantages that
(1) present invention improves the usage degree of drill point to the maximum extent, reduces under the premise of guaranteeing drilling quality
Drill point cost in PCB bore operation.
