What you're seeing is Inverse Time feedrates: https://diy.haascnc.com/reference-docs/inverse-time-and-feed-minute-modes

 

G93 Inverse Time

G93, Inverse Time Mode ON, translates the linear (inches/mm) feedrate into a value that takes rotary motion into account. G93 specifies that all F (feedrate) values are interpreted as strokes per minute. In other words, the time (in seconds) to complete the programmed motion using G93 is 60 (seconds) divided by the F value.

G93 is generally used in 4 and 5-axis work when the program is from a CAM system. When you use G93, the F value tells you how many times per minute the stroke (tool move) can repeat.

When G93 is used, feedrate (F) is mandatory for all interpolated motion blocks. Therefore, each non-rapid motion block must have its own feedrate (F) specification.

Program code G93 to start Inverse-Time mode.

G93 was introduced in Mill software version 9.22.
