For V9.0, you have 2 options
1/- extend your geometry
2/- use "Lead in/out" , this will add additional movement to the start and endpoints of your contours , the arc is the entity the connects to your geometry , the line is the extension onto the arc along which the cutter comp. is taken up, ( or if at the end, cancelled )
On many machines, cutter comp is taken up or cancelled on a line only
-if you use "Wear" , then the compensation value in the control should be 0(zero) , lead in / out ( lines & arcs ) can be zero or +ive. ( you are programming the tool centreline)
-if you use "Control" , then the compensation value in the control should be the tool radius , lead in / out ( lines & arcs ) can be zero or greater than the tool radius.( you are programming to the part contour )
If you can get V9.1 or .2 - go for it , it has more options in the lead in / out area ( eg extend/shorten path ) |
