Peck Cycle, Full Retract

I recently had a customer that needed to drill some deep holes with multiple drills and needed a full retract.

 

Typically this is a good solution for a macro, except, that they know zero about macros and are not even sure that they have Macro B. So I needed a Mastercam solution....so here is a custom cycle for anyone who can use it

 

 

I created a new fs statement for rounding, if you already have an fs22 change it to something you don't have, just make sure you set the variable for the new fs statement

fs2 22  3 09 3 09   #Output for rounding peck values

variables to be defined

fmt      2  drill_dist  #calulate drilling distance
fmt      2  pck_amt     # Peck amount
fmt      22 pck_no      # Calculate no. OF PECKS
fmt  Z   2  drl_depth   # Calculate Z drill depth
fmt  Z   2  z_return    # Rapid Z dpeth
fmt  Z   2  rtr_hgt
fmt      2  z_calc      #calulated Z doeth
fmt      2  prv_zdrill  # Capture previousl drilled depth
fmt  Z   2  z_clear     # Z clearance return value
fmt      2  z_clear_val  # Clearance distance to previous peck
fmt  Z   2  z_start_pos

pass      :-9999       # Calculate number of pecks remaining

Define the custom call

pdrlcst$         #Custom drill cycles 8 - 19 (user option)
      #Use this postblock to customize drilling cycles 8 - 19
      if drillcyc$ = 8, pdrilldeep
      if drillcyc$ > 8, pdrlcst8

The actual cycle

      
pdrilldeep
      pdrlcommonb
      pck_amt = peck1$
      drill_dist = (-depth$ + tosz$)
      pck_no = (drill_dist/ pck_amt)
      pck_no = fmtrnd(pck_no)
      pass = pck_no
      rtr_hgt = peckclr$
      z_calc = 0
      z_clear_val = peck2$
      z_clear = (tosz$ + z_clear_val)
      z_start_pos = initht$
      
      pbld, n$, pxout, pyout, e$
      pbld, n$, sg00, *rtr_hgt, e$
      while pass > 0,
      [
      drl_depth = ((tosz$-(pck_amt)) + (-z_calc))
      pbld, n$, sg00, z_clear, e$
      pbld, n$, *sg01, *drl_depth, *feed, e$
      pbld, n$, sg00, *rtr_hgt, e$
      
      prv_zdrill = drl_depth
      z_calc = z_calc + pck_amt
      z_clear = (prv_zdrill + z_clear_val)
      pass = pass - 1
      ]
      
      z_clear = (prv_zdrill + z_clear_val)
      pbld, n$, sg00, z_clear, e$
      pbld, n$, sg01, pfzout, *feed, e$
      pbld, n$, sg00, z_start_pos, e$
      pbld, n$, "(", "HOLE COMPLETE", ")", e$
      pbld, n$, "(" ")", e$
      pcom_movea

The field changes

[drill cycle 9]
1. "PECK SPECIAL"
2. ""
3. ""
4. ""
5. ""
6. ""
7. "Peck"
8. "Clearance Distance"
9. "Clearance Height"
10. ""
11. ""

Peck = Amount of Drill Peck

Clearance Distance = Distance away to rapid down from previous drilled depth

Clearance Height = Height to retract to clear hole.

and if you want to setup to do multiple holes

pdrlcst_2$       #Custom drill cycles 8 - 19, additional points (user option)     
      #Use this postblock to customize drilling cycles 8 - 19
      if drillcyc$ = 8, pdrilldeep
      if drillcyc$ <> 8, pdrlcst8_2

I see there is a redundant F4.04, how do I remove all of them but only leave one F4.04?

 

 

Thanks.
