Here is a very helpful video on 'how-to' setup a subplate with SpeedLoc by mPower.
Types of Workholding There are many ways to skin a cat. Dedicated fixtures have more or less fallen by the wayside just like dedicated transfer lines. This trend will probably continue for two primary reasons:
Modular fixturing is the buzzword. “Modular” takes on numerous forms from a variety of manufacturers. It can be as simple as components and clamps that are assembled into a “dedicated” fixture for a job but then can be disassembled and the components used for another job.
The key to modular tooling is that you start with a good “foundation”. The foundation for most modular systems is a tombstone or subplate. Modular fixturing allow you to make “dedicated” fixtures that can be disassembled and reused for other “dedicated” fixtures.
Modular fixturing is a very good solution for longer part runs or fixturing very hard to hold part shapes.
SPEED is the KEY! Modular fixturing is a great idea, but as your customers begin to demand faster turnaround and smaller lot sizes just the fact that you can re-use your tooling components doesn’t always help. What matters, remember, is spindle up-time.
Taking apart your components and setting up others takes TIME. So there has been a demand for new innovations from Workholding manufacturers in both modular AND Quick Change fixturing. Have you ever found yourself thinking: “I need fast set-ups, good repeatability, and quick changeover… and I want the tooling to be modular to a point where I don’t have to completely disassemble everything.”
Reducing set up times in workholding start with the foundation. You want to have the ability to move your fixturing from Vertical to Horizontal CNC's as lot sizes of parts increase or back to the Vertical CNC as lots sizes reduce.
Foundation level systems are systems that you can build dedicated or modular fixtures on and quickly remove them for another set-up.
They will also allow you to set up you fixtures off-line. That is, they will allow you to set the fixtures up OUT of the machining center. They key benefit to this is that you can still continue to make chips on one job while setting up another outside of the machine
Another major benefit to these types of systems is that they will enable you to make quick changeovers. If your total “in-the-cut” machining time is 5 minutes but it takes you 10 minutes to change out the new parts and put in more raw material these system can save you a great deal of time.
There are two issues to look at when considering a certain type of fixture:
The mPower SpeedLock and ModLoc fixturing system show in the video above is one of the foundation systems that you may want to consider as part of a shop wide set up and changeover reduction process.
Consider all of the types and sizes of the parts in your shop and then determine which baseplate size to start with that can provide you with the most versatility.
The process of standardizing your workholding will take some time, but once complete you can move jobs around with the same simplicity as when your kids are playing with their lego's.
