Controlled corner rounding, radius blend, (G05/G61)
·199·
(REF: 1709)
The distances from the programmed point to the points where the corner rounding begins
and ends are calculated automatically and they cannot be greater than half the path
programmed in the block. Both distances will be the same, except when one of them is limited
to half the programmed path.
For this type of corner rounding, only the values of the first two parameters of the
"#ROUNDPAR" instructions are used, therefore, all parameters need not be included.
Type 3
#ROUNDPAR [3,a,b]
It defines the distance from the programmed point to the points where corner rounding begins
and ends.
For this type of corner rounding, only the values of the first three parameters of the
"#ROUNDPAR" instructions are used, therefore, all parameters need not be included.
Type 4
#ROUNDPAR [4,e]
Set the maximum deviation allowed between the programmed point and the profile resulting
from rounding the corner.
The corner is rounded by giving priority to the machining geometrical conditions. The
programmed machining operation is executed by decreasing the programmed feedrate "F"
if necessary.
#ROUNDPAR [2,f]
f: Porcentage of feedrate "F" for corner rounding.
#ROUNDPAR [3,a,b]
a: Distance to the starting point of corner rounding.
b: Distance to the end point of the corner rounding.
Depending on parameters "a" and "b", a deviation may occur at the programmed profile (as shown
in the example).
