Engineering Standards For Estimating

Process Automation on the Gears.Engineering standards for estimating is critical in order to come up with a consistent way of quoting.   Standards are based on time and not dollars because shop rates are different based on each individual company.  Standards are different based on machines and skill which are relatively consistent.

Engineering standards shown are for the metalworking industry and can be adjusted based on your machines and skill level.  Software has improved greatly in the last few years with software from vendors such as Metamation Inc., Sigmanest  and others.

Sheet Metal parts take about 20-60 minutes to program or 3 minutes per 1 minutes of machine time.  CNC Lathe parts take about 20-60 minutes to program or 10 minutes per 1 minute of machining.  Machining Center takes 4-40 Hours or 30  minutes to program 1 minute of machining time.

Tool design for fixtures, drill jigs, welding jigs, etc has been approximated that the manufacturing time and cost will be 2 times greater.

You should create a spreadsheet for estimating that uses the standards shown or use an estimating software like QuoteIt! from MIE Solutions to enter the formulas which best match your requirements.

David Ferguson has been to over 100 manufacturing companies helping and guiding them to be more efficient and cost effective. As a child in Junior High School David Ferguson found a passion for the early computer systems, which would drive much of his future work. David Ferguson created and sold his first computer program, Arrow Data Systems, which was an early CAD/CAM system for the Apple 2e Computer. In the late 1980's after seeing his father (a sheet metal manufacturer) come home many nights estimating, David Ferguson saw an opportunity to optimize his effort through computer technology. Shortly thereafter the FabriTRAK Production Control package was developed. The Quote It! estimating package was developed out of the FabriTRAK system to become one of the leading sheet metal estimating packages in the world. David Ferguson has always had a passion for developing software to make the manufacturing process simpler, faster and more efficient. Prior to founding MIE Solutions David Ferguson worked with his father at Alco Sheet Metal, METALSOFT Inc. and was a consultant at Toyota Motors Sales. David Ferguson has his Masters in Computer Science and Mathematics from California State University, Long Beach.
