Also speeding operations is the gantry loader, which quickly loads/ unloads parts, thereby reducing machine idle time
The Schunk Zero Point pallet system has helped Machine Specialties reduce its machine idle time
, improve part throughput from operation-to-operation and machine-to-machine, as well as provide greater flexibility with machine job allocation, all accomplished without sacrificing accuracy, repeatability, and rigidity.
This resulted in significant reductions in machine idle time
, which reduced overtime costs by 40 percent.
Check machine capacities, formula time, machine idle time
, soiled-linen delivery schedules, etc.
Machine uptime is measured in percentage of scheduled time and can depend on the amount of downtime for clean-up, breaks, and sand delivery as well as machine idle time
while waiting for core racks.
Actual energy savings will depend on the length of the machine idle time
relative to the overall cycle time.
Benefits for the customer will be reduced surveying manpower, less machine idle time
and improved job quality resulting in a lower cost for the movement of material."
In order to assess performance criteria for each plant layout, mathematical models based on queuing theory principles were developed to enable the performance of each generic plant layout to be assessed on relative costs of WIP and machine idle time
. Queuing theory has its origins in the early 1900s for the design of telephone systems.
But if they reduced the machine idle time
by providing a faster tool change and chip-to-chip time, the improvement would be about 6%.
"We really underestimated how much setup time, part-handling, and machine idle time
was costing us."
A "side-by-side" view of turret activity also allows synchronization points to be moved around to reduce machine idle time
This optimizes turret use, helps prevent turret and spindle conflicts, and allows synchronization points to be moved to minimize machine idle time
. It is also indispensable for turret and spindle synchronization, collision avoidance, establishing turret priorities, and resolving potential conflicts.
