The variable tool.maximumSpindleSpeed appears to only be set by the operation. I would like to be able to store the tool.maximumSpindleSpeed within the Tool Library. There isn't a field. This variable is especially important when using constant surface speed on the lathe. It should be setable on the Feed & Speeds tab.
I looked through the tab separated value (.tsv) backup of my tool library and the variable is not there.
