Custom Chip Break drill cycle

[Guest]

I seen a couple of discussions in the past about a chip break cycle with a full retract.

 

Well here's one if anyone thinks they can use it.

 

You set your top of stock & total depth as normal, you add a peck amount, # of full clearance moves you want and the height above the next peck start.

 

If you want to start at .05 abouve on the pecks, place .05 in, if you want .01 put it in.

 

Formatted variables

 

code:

---

fmt Z 2 inc_depth

fmt 4 no_step

fmt 2 total_depth

fmt 4 pass

fmt 4 count

fmt Z 2 cut_depth

fmt Z 2 cut_1

fmt Z 2 rpt_cut

fmt R 2 r_plane

fmt 2 r_hght

Custom cycle

code:

---

pdrlcommomb

if drillcyc$ = 8,

[

no_step = peck2$

r_hght = retr$

total_depth = depth$ - tosz$

inc_depth = total_depth / no_step

cut_1 = tosz$ + inc_depth

pbld, n$, *sgdrlref, *sg73, pdrlxy, *cut_1, prdrlout, *peck1$, *feed, e$

pass = 1

count = no_step - 1

rpt_cut = cut_1

r_plane = cut_1 + r_hght

while count > 0,

[

rpt_cut = cut_1 + (inc_depth * pass)

pbld, n$, *sgdrlref, *sg73, pdrlxy, *rpt_cut, *r_plane, *peck1$, *feed, e$

pass = pass + 1

count = count -1

r_plane = rpt_cut + r_hght
