Minimum deceleration ratio (MDR) of the inner circular cutting rate in
automatic corner override
[Data type] Byte
[Unit of data] %
[Valid data range] 1 to 100
This parameter sets the minimum deceleration ratio (MDR) when the
inner circular cutting speed is changed by automatic corner override.
In circular cutting with an inward offset, the actual feedrate
for a specified feedrate (F) is expressed as follows:
Rp
Rc
F ×
Rc: Radius of the path of the cutter's center.
Rp: Programmed radius
Then, the actual feedrate is controlled so that the feedrate on the
programmed path can achieve the specified feedrate F.
Rp
Rc
Path of the
cutter's center
Programmed path
Fig. 4.17 (a) Rp and Rc
If Rc is too small in comparison with Rp, such that Rc/Rp
0, the
cutter will stop. To prevent this, a minimum deceleration ratio (MDR)
is set.
1711
Angle (θp) used to recognize an inner corner in inner corner override
[Data type] Byte
[Unit of data] Degree
[Valid data range] 1 to 179 (standard value = 91)
This parameter sets the angle used to recognize an inner corner for
inner corner override by automatic corner override.
1712
Amount of override for an inner corner
[Data type] Byte
[Unit of data] %
[Valid data range] 1 to 100 (standard value = 50)
Set the amount of override for an inner corner.
