Fig. 4-22 Set lead-in/out line
CAUTION
There is no obvious boundary between line-type lead in/out and arc lead in/out in
operation, so the two can be exchanged with each other. For instance, if users set
arc-type lead in/ out to a rectangle, the system still calculates its line-type lead
in/out automatically.
The type of lead-in/out line is chosen in terms of cutting technique; besides, the
use of lead-in/out line is for precise machining, the user can decide whether to set
it or not.
Angle: included angle of two edges of lead-in/out line.
Length: length of cut-in edge or cut-out edge of lead-in/out line.
Seal Len: range of seal length is from -500 to 500.
Seal length decides whether lead-in/out line is cut-out or seal lead-in/out line.
In case of a negative value, under-cut will appear, i.e. this is a cut-out lead-in/out line.
In case of a positive value, over-cut will appear, i.e. this is a seal lead-in/out line.
Cut Mode: fill, unfill and changeless (with no change to current cut mode) are available in cut mode.
Seg No.: there are probable N straight lines (N is a natural number) on the selected object.
‗‘Segment No.‘‘ refers to the sequence number of the segment on which the lead-in/out line is
among all the segments of the selected object (It is used to fix the location of lead-in/out line on a
certain segment).
Pos Ratio: it refers to the ratio of the distance from the position of lead-in/out line on a segment to
the beginning of this segment to the whole length of the segment, and its range is [0, 0.999].
Simplified: this button is to switch between simplified and advanced setting. Under simplified mode,
segment No. and position ratio are not available.
Manual Set: after clicking this button, the position of lead-in/out line can be set manually.
