Item Details
Theoretical The theoretical arc radius reduction[mm]
radius reducing for an arc with radius R is calculated
difference based on the data of the parameter
[mm] used.
Command path
in G-code program
R5mm arc clamp The arc deceleration speed[mm/min] for
speed an arc with radius of 5mm is calculated
[mm/min] based on the data of the parameter
used.
R1mm arc clamp The arc deceleration speed for an arc
speed with radius of 1mm is calculated based
[mm/min] on the data of the parameter used.
