Circular pattern in XY plane
Reference data of XY plane:
ID : Contour
PT : Milling depth
C
:
Spindle angle
IR : Limit diameter
ZR
:
Reference dimension
Parameters of pattern:
X
,
Y
:
Center
of pattern
QP : Quantity of points in pattern
DR : Dir.rot. (default: 0)
DR = 0, without EP : Figures are arranged on a full circle
DR = 0, with EP : Figures are arranged on the longer circular
arc
DR
= 0, with
EPi
: The algebraic sign of
EPi
defines the
direction ( EPi < 0: clockwise)
DR
= 1, with
EP
: clockwise
DR = 1, with EPi : clockwise (algebraic sign of EPi has no
effect)
DR = 2, with EP : counterclockwise
DR
= 2, with
EPi
: counterclockwise (algebraic sign of
EPi
has
no effect)
DP : Diameter
AP : Start angle (default: 0°)
EP : Final angle (no entry: the pattern elements are distributed
evenly around 360°)
EPi : Final angle – Angle between two figures
H
:
Element pos
0: Normal – The figures are rotated around the circle center
(rotation)
1: Master – The position of the figure relative to the
coordinate system remains unchanged (translation)
Parameters of the selected figure/hole
You can use the
Select reference plane
function to determine the
Reference dimension ZR and the Limit diameter IR .
