1.6.4 Arbitrary Figure Blocks for Pocketing (XY Plane)
When an arbitrary figure for pocketing is input, data such as a figure
type and machining reference position is specified in the start point
block. Other data items to be input such as a straight line and arc are
exactly the same as for arbitrary figures of other machining types.
So, this subsection describes only the start point block of an arbitrary
figure for pocketing.
For other arbitrary figures, see Chapter 5, "DETAILED
DESCRIPTIONS ABOUT ENTERING ARBITRARY FIGURES," in
Part II.
Start point: G1200 (XY plane)
ELEMENT
Data item Meaning
X START POINT X X coordinate of the start point of an arbitrary figure
Y START POINT Y Y coordinate of the start point of an arbitrary figure
T FIGURE TYPE
[FACE] : Used as a figure for facing
[CONVEX] : Used as an outer figure for contouring
[CONCAVE] : Used as an inner figure for contouring or as
a figure for pocketing
[GROOVE] : Used as a figure for grooving
Remark) When pocketing is selected as machining type,
be sure to select [CONCAVE].
B BASE POSITION Z coordinate of the top surface of a workpiece subject to
pocketing or the bottom of a pocket (in the tool axis
direction)
L HEIGHT/DEPTH When the top surface of a workpiece is selected as the
BASE POSITION, specify the distance to the bottom of a
pocket by using a negative value (radius value).
→ Depth
When the bottom of a pocket is selected as the BASE
POSITION, specify the distance to the top surface of the
pocket by using a positive value (radius value).
→ Height
