1) Screen explanation
Select when backboring. It can be done when the positioning of the spindle is possible. It is possible to
select up to 10 tools, including the tool used for pre–hole machining. The chamfering tool is automatically
selected.
2) Input item explanation
I : RETURN POINT
Input the Z coordinate of the point to which the tool will return in rapid traverse mode after the cutting
feed. Be sure to input when back boring.
U : THICKNESS
Input the thickness of the workpiece. Be sure to input.
X : SHIFT OF X
Y : SHIFT OF Y
After the spindle stops at the fixed position when backboring, release the cutting tool so that it does
not interfere with the inner wall of the workpiece.
When performing a canned cycle, input one of the two values. Which value to be input depends
on the settings of bit 4 (RD1) and bit 5 (RD2) of parameter No. 5101.
Be sure to input.
YA : CUTTING DEPTH OF ONE PATH
When cutting a workpiece with a certain thickness by several paths, input the cutting depth of one
path. When no value is input or 0 is input, THICKNESS (U) is assumed to be the cutting depth of
one path. It is automatically decided using the [F.S.AUTO] soft key. After automatic decision, the
value can be altered if necessary. The angle/sizing value corresponding to the value input in TOOL
ID NO. (T) is read from the tool file and displayed.
