How do you maintain consistent tool life across long produ

In higher-volume CNC production, we sometimes see noticeable variation in tool life even when cutting the same material (mainly 6061, 7075, and 17-4), using the same CAM strategy and the same batch of tools.

Factors like spindle thermal behavior, coolant concentration, or chip saturation seem to influence tool wear more than expected.

I’m interested in how other production environments approach this:

Do you monitor load/horsepower per tool to adjust tool life dynamically?

Do you track coolant concentration daily or automate it?

Any experience with stabilizing tool wear by adjusting ramp-in strategies or stepdown ratios?

We already log wear offsets per batch, but I’d like to compare notes and see what methods others use to make tool life more predictable and stable over long runs.
