7.3.1 Types of corner rounding
There are 5 different corner contouring types. The first 4 execute the
different corner rounding types whereas the last one executes a
square corner. The last one is aimed at special machines (Laser,
water jet, etc.), that use it to avoid "burning" the corner, thus not being
recommended for a milling machine.
Corner rounding is selected and defined through the parameters
associated with the "#ROUNDPAR" instruction. This instruction may
have associated up to 6 parameters whose meaning will depend on
the type of corner rounding selected.
Type 1 #ROUNDPAR [1,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 dynamic
conditions (feedrate and acceleration). It executes the machining
operation that is closer to the programmed point without exceeding the
programmed deviation and that does not require decreasing the
programmed feedrate "F".
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.
#ROUNDPAR [1,e]
e : Distance between programmed point and real profile.
