Lathe ? For CNC

[Don S at Barefoot CNC South]

Hi all

Why arn't any of the lathe X posts setup to use stock advance? At least some kind of generic start point in the post would help. Are all the misc ops that way also? I have a Daewoo lathe post from version 9 updated to X2 and am trying to add this in. Also mplmaster lathe post isn't setup either.

Thanks

I'd tell you, but I'm a little busy right now.

 

j/k, I have no clue

If you look in the NCI file for "900" you will

see the numbers that come from the settings

in job setup - then look in the post for"900"

and you will see the defintions for each of

the spindle moves - problem is as the post

comes standard it does nothing with those numbers

it just goes to the predefined block and outputs "stock transfer" - currently trying to

make this work on a Mazak myself - any hints

or help appreciated

Hi Don,

 

Stock advance or stock transfer?

[Don S at Barefoot CNC South]

Greg

stock advance

[Thee Dragracer1951]

I'm also interested in this Don.

[Don S at Barefoot CNC South]

I wish sombody from CNC would respond.

If you're talking bar-feeder or bar-puller, (don't get this wrong Stork), I just hard coded a few postblocks right after pheader using misc integers to flag wether or not to use the routine and misc reals to provide needed data.

Can also create a template as a manual entry

toolpath - save it - and fill in the numbers

for each op when you call it up

Don have you sent a request off to CNC via email on this??

[Don S at Barefoot CNC South]

yes a year ago

[Don S at Barefoot CNC South]

Ron

I just sent it to them again.

[crazy^millman]

I will send one off as well.

Look in mplfan

code:

---

pstck_trans$ #NCI code = 900 available variables:

#stck_spindle, stck_init_z, stck_final_z,

#stck_chuk_st_z, stck_chuk_st_x,

#stck_chuk_end_z, stck_chuk_end_x,

#stck_chuk_st_dz, stck_chuk_st_dx,

#stck_chuk_end_dz, stck_chuk_end_dx

if toolchng <> two, ptoolend$

toolend_flg = zero #Do not execute ptoolend again after xfer

[

!spaces$

spaces$ = zero

pbld, n$, "M00",e$

if prv_spaces$ > 0, " ",e$

if stck_spindle$ = 0, "(Xfer Part from Left Spindle)", e$

if stck_spindle$ = 1, "(Xfer Part from Right Spindle)", e$

spaces$ = prv_spaces$

]

---

each different type of op has the different variables listed at the top of the post block.

 

What output are you lookin for?

[Don S at Barefoot CNC South]

That is for stock transfer, I am looking for stock advance using stock stop or bar puller.

Thanks

The explainations are right above there:

code:

---

 # --------------------------------------------------------------------------

fmt Z 2 stck_init_z$ #Initial Z position of the stock (900-902,904,905)

fmt Z 2 stck_final_z$ #Final Z position of the stock (900-902,904,905)

fmt Z 2 stck_chuk_st_z$ #Initial Z axis Chuck Position (900-903)

fmt X 2 stck_chuk_st_x$ #Initial X axis Chuck Position (900-903)

fmt Z 2 stck_chuk_end_z$ #Final Z axis Chuck Position (900-903)

fmt X 2 stck_chuk_end_x$ #Final X axis Chuck Position (900-903)

fmt W 3 stck_chuk_st_dz$ #Destination chuck Z axis reference position before transfer (900)

fmt U 3 stck_chuk_st_dx$ #Destination chuck X axis reference position before transfer (900)

fmt W 3 stck_chuk_end_dz$ #Destination chuck Z axis reference position after transfer (900)

fmt U 3 stck_chuk_end_dx$ #Destination chuck X axis reference position after transfer (900)

fmt Z 2 stck_clear$ #Stock clearance value for stock pull operation (902)

fmt X 2 stck_tool_x$ #Tool X axis position for bar stop / puller (902)

fmt Z 2 stck_grip$ #Grip length value for stock pull operation(902)

 

fmt F 18 stck_adv_fr$ #Used with Lathe Stock Advance (Bar-Feed/Pull) function (NCI 902)

fmt F 18 stck_appr_fr$ #Used with Lathe Stock Advance (Bar-Feed/Pull) function (NCI 902)

 

#Flags

stck_op$ : 0 #Stock advance operation method (902)

#(0=Push stock,1=Push stock with Use Tool Stop option,2=Pull stock)

stck_spindle$ : 0 #Active spindle with stock to transfer (900-902)

#0=Left Spindle,1=Right Spindle

clmp_op$ : 0 #The selected Operation mode: 0=Clamp,1=Un-clamp,2=Re-position (903)

clmp_spindle$ : 0 #Active spindle for clamp/unclamp 0=Left Spindle,1=Right Spindle (903)

tlstck_on$ : 0 #Retract or engage the tailstock (0=Retract,1=Engage) (904)

 

toolend_flg : 1 #Flag to execute ptoolend sequence or not

 

 

# --------------------------------------------------------------------------

---

Then the bar pull/stop:

code:

---

pstck_bar_fd$    #NCI code = 902 available variables:

#stck_spindle, stck_op, stck_clear,

#stck_grip, stck_init_z, stck_final_z,

#stck_chuk_st_z, stck_chuk_st_x,

#stck_chuk_end_z, stck_chuk_end_x,

#stck_adv_fr, stck_appr_fr

if stck_op$ <> 1, # if NOT using the 'Tool Stop option'

[

if toolchng <> two, ptoolend$

toolend_flg = zero #Do not execute ptoolend again after xfer

]

else,

toolend_flg = one #DO execute ptoolend after xfer

 

[

!spaces$

spaces$ = zero

pbld, n$, "M00",e$

if prv_spaces$ > 0, " ",e$

if stck_op$ = 0, "(Push stock -",e$

if stck_op$ = 1, "(Push stock with Use Tool Stop option -",e$

if stck_op$ = 2, "(Pull stock -",e$

if stck_spindle$ = 0, " from Left Spindle)", e$

if stck_spindle$ = 1, " from Right Spindle)", e$

spaces$ = prv_spaces$

]

What output do you need? Put up a sample or email me.

Don, Good luck! Lathe support stinks in MC for Lathe. If you can't get it running from the above post shoot me an email and the way you want you code to look and I'll throw it together for ya! I've set up advance and transfer successfully a quite a few times now.
