Production of repeat parts:
Review the engineering drawing to verify that the set up sheet and program apply to the current revision level.
Set up and operate CNC machine centers in accordance with established Set Up Sheets on file for production parts.
Verify that parts produced comply with specified requirements through first part inspection and routine production inspections as required.
Where appropriate, offer suggestions for changes to established Set Up Sheets that will improve the quality of the parts or reduce the time required to produce them.
Where no Set Up Sheet exists (one-off and R & D parts):
Examine input information (engineering drawings, sketches, sample parts) to determine dimensions and tolerances of finished part, sequence of operations and setup requirements.
Create a program and setup sheet.
Select, align and secure holding fixtures, cutting tools, attachments, accessories and material to ensure the work is properly positioned and securely held.
Calculate and set controls to regulate factors such as speed, feed rate, coolant flow and depth and angle of cut.
Start and observe machine operation to detect malfunctions and any process errors that would produce unacceptable (out of tolerance) parts. Where machine or process issues arise, take appropriate corrective action.
Confer with engineering and/or production personnel to resolve manufacturing or assembly issues.
Verify, through a systematic inspection that finished part conforms to specified requirements.
