Leonard Singel

I have worked in the trade since February 1977 and for the last 37 years at Ronal. I have used all shop equipment from Mills, Lathes, Grinders, Wire EDM and Sinker EDM. Using all measuring equipment made parts from sketches and drawling. Built Die parts and Whole Dies. Built Mold tooling and Molds completely from start to finish. along the way making tooling parts from all kinds of Steel from Tool steels A-2 D-2 CPM-10 to all the stainless steels to titanium. All of these require the knowledge to what type of tooling and the machinery to manufacture a good

quality part. I've taken dies that were running parts with a problem, pulled them apart and diagnosed the tooling issues and machined the replacement parts installed them and got the Dies running properly again. Inspected parts before and after to make sure the parts were to specs.

During the time spent at Ronal we had a number of Apprentices that I had a big hand in training them on our shop equipment and emphasize the need for safety while doing there job correctly.

• Set up and operated various machine tools to produce precision parts and instruments.
• Maintained quality and safety standards; kept records of maintenance and repair work.
• Calculated dimensions and tolerances using knowledge of mathematics and instruments such as micrometers or vernier calipers.
• Read blueprints, skhes, drawings, manuals, specifications or sample part to determine dimensions and tolerance of finished work piece.
• Adjusted machine feed and speed, changed cutting tools, or adjusted machine controls when automatic programming was faulty or if machines malfunctioned.
• Verified conformance of finished work piece to specifications by checking measurements with a variety of precision measuring instruments such as height gauges, surface plates and protractors.
• Observed machine operations to detect malfunctions or out-of-tolerance machining and adjust machines accordingly.
• Changed worn cutting tools as needed during operation.
• Trained new employees in the use of machinery used in the manufacturing process.
• Selected appropriate speeds and feeds according to metal type and finish specifications.
• Observed operating machines or equipment to diagnose machine malfunctions and determine need for adjustments or repairs.
• Read and followed blueprints, diagrams and drawings to fabricate products.
• I operated horizontal boring mills, CNC machining centers. Lathe Mills and Grinders
