I'm exploring an idea to automatically measure the runout of a spindle probe every cycle. It would then measure locations and update work offsets.
I have failed to find an indicator with output that would work at all. There are some that would do what I need, but they are either not sealed well enough to survive that environment, or they have too much deflection pressure; Ie the indicator would deflect the probe, not the other way around.
Machine is Brother R650 and probe is Blum TC-52. Budget is $3,000 or so to outfit two machines and preferably have a spare tool.
Requirements for this tool is:
- Coolant proof to survive inside a CNC mill full time
- 1nm measuring force max (probe deflection force is 1.5nm)
- Be able to measure TIR and report if out of a given tolerance: IF [TIR GT .0003] SEND SIGNAL ... type of thing
- Preferably hard wired for power, but batteries would be ok if the device can be made to alarm the machine if the batteries die
If such a tool exists, I'll need to know:
- How to trigger the start of measurement from within a program
- How long the TIR cycle will take in seconds
- How to deal with I/O to be able to use macros to decide what to do with the information gathered.
