Machine tool leader Mazak Corp. introduced multi-tasking by marrying an automatic tool changer and two-position spindle with a slant-bed lathe in the mid 1980's.  While a powerful new way of thinking about machining processes was born, the challenge of designing for the multi-tasking capability is ongoing, says Brian Papke, President. The goals of multi-tasking include the following:

1. Reduce direct cost -- fewer machines, fixtures, tools and far less labor.

2. Slash non-value-added time, multiple setups, part handling and queue time.

3. Compress lead-time -- from days or weeks to hours.

4. Improve cash flow -- smaller, frequent shipments on customer demand.

5. Reduce work-in-process (WIP) inventory -- releasing cash for operations/investment.

6. Improve part accuracy -- no tolerance build-up from multiple setups.

7. Reduce indirect costs -- less floor space, utilities and maintenance.

8. Reduce lot sizes with no cost penalty -- lots-of-one or assembly kits.

9. Run "lights-out" with automation -- more cutting time with no added labor.

10. Improve customer satisfaction.

11. Improve competitiveness -- seek new customers and markets.

12. Greater profitability.
