Make sure automated machinery is programmed and running properly.
Sets up and operates numerical-control drilling machine to drill holes into printed circuit boards: Reviews setup instructions and specifications. Loads control media containing programmed commands into control console of machine or enters commands to retrieve programmed control data. Attaches depth collars to drill bits and measures bit depth, using depth gauge, to verify specified drill bit cutting depth. Measures drill bit sizes, using micrometer, and installs specified drill bits in tool magazine of machine. Positions and secures PCB’s to indexing table of machine. Enters commands to activate machine that automatically aligns indexing table and printed circuit boards under spindle, selects drill bit, and drills holes of specified dimension, location, and sequence into PCB’s. Monitors machine operation and display readouts to detect malfunctions. Compares display data to specifications and notifies supervisor of machine malfunctions. Inspects and measures drilled PCB’s to verify conformance to specifications, using measuring devices, such as micrometer, plug gauges, and test board. Performs machine adjustments and maintenance, such as setting speed and feed rates, cleaning machine parts, and replacing worn or damaged drill bits, using handtools.
