4600 T, C COMMAND IN
INTERPOLATION
In the linear interpolation (G01) mode
or circular interpolation (G02, G03)
mode, a T command or C–axis com-
mand was specified.
Under normal direction control, a punch press shears a sheet while
holding the sheet and moving the tool with interpolation. The cutting of
an arc should be programmed as follows: Linear positioning is performed
with the C–axis set in the direction normal to the tangential direction at
the start point of the arc; The sheet is held by the PF signal; A C–axis
normal–direction movement is made with circular interpolation. The
program should be created so that an arc and a straight line are connected
by a tangent even in the normal direction control mode.

² Positioning for creating a tangent at the start point of
the arc (G70: Positioning and press off command)
² Positioning to the arc start point with the C–axis set in
the direction normal to the direction of the arc tangent
The PF signal lowers the rams to hold the sheet.
