The return distance must not exceed the length of one block.
Return peak value Sb' can be specified in parameter No. 15059.
This is intended to use the output peak value Sb' that is different
from the peak value Sb of block B during movement through the
distance Lr. If this parameter is 0, machining is performed with
Sb' = Sb.
Selecting the edge function
The edge machine function is enabled by setting an edge data number
from 201 to 205 in the "edge selection" item in the machining data
group. To disable this function, reset the "edge selection" item to 0.
Edge machining command
If a program specifies a machining data set number using the E
address, when the program is executed, the "edge selection" item in
the specified machining data is referenced, and the edge data set
number is read for edge machining.
Cutter compensation
If a very small block is created for cutter compensation, angle decision
is made on the angle made by the current block and the very small
block, resulting in the angle differing from the one specified by the
program. If cutter compensation is applied during edge machining, a
very small block is created at the edge, causing the following
operations.
1 Piercing is performed before the very small block created for
cutter compensation.
2 Execution of the very small block begins with the return data,
and operation continues to the next block. After the return
distance is moved through, the programmed machining
conditions are applied.
To execute edge machining with the path on the machining
program in cutter compensation mode, set bit 3 of parameter No.
