Need help with generic Haas TR series 5X Mill post

[MSL]

Hi,

I’m working on a post for a Haas TR-160Y Trunnion Table. I need to activate the A & B axis break when I’m doing a positioning cut and deactivate when operation is done. Also need to disable A & B axis break when I’m doing a 5 Axis drilling.

I'm using the generic Haas TR series 5X Mill post that comes with Mastercam.

Using X6MU2

Thanks in advance.

Ara.

Are you referring to the M10 - M13 clamp codes?

If so there is a variable in the post called "use_clamp"

 

use_clamp : 1 #Use the automatic clamp Mcode <<< Make certain the value is set to one and it will be active.

Thanks for the reply.

Yes, I'm referring to the M10 - M13 clamp codes. I have the auto clamp set to 1 now. I don’t want to have the clamp on when I’m doing 5 axis drilling. Only want them when I'm doing a positioning cut. I want my axises to be clamped so I can cut more rigid.

Thanks.

I don’t want to have the clamp on when I’m doing 5 axis drilling.

 

That would require some custom post editing,...

 

Do a search for "use_clamp"

 

#Lock rotary axis

#if use_clamp & (cuttype = zero | opcode$ = three | opcode$ = 16), <<<< I copied this line of code below, the pound sign will cause the post to ignore it

 

if use_clamp & cuttype = zero, <<< to turn off the clamping for drilling remove the opcode$ 3 & 16 information

 

You will need to do a search for all instances of this, opcode 3 is for drilling toolpaths opcode 16 is for 5axis drilling.

 

In the punclamp post block you'll need to make changes as well.

 

punclamp #Unclamp the rotary axis

if use_clamp,

[

#Force both rotaries to unlock if multi-axis

#if cuttype <> zero & opcode$ <> three & opcode$ <> 16 & (p_lock = one | s_lock = one), <<< change this line to look like the one below

 

if cuttype <> zero & (p_lock = one | s_lock = one),

Thank you for the help.

That worked out pretty good. The only thing is I need to un clamp it when I'm done with cutting.

Thanks.

In pretract, you can call punclamp in the line before the optional stop. That way the post keeps track of the condition.

Thanks for the help. That worked out perfect.

ara,

 

Did you have problem in the 5 axis drilling where it wants to move the A axis back and forth on simple drilling?

No, I just didn't want to have clamp called out when I'm doing 5 Axis drilling.

Hi CNC Apps Guy.

I just find out that it does unclamp only when I post multiple ops (when it see M01). If I only post one op. it won't unclamp in the end as I post out my codes above. Can you show me where to add the punclamp in the post please, I might placed it in a wrong place.

Thanks.

[CJep]

Ara,

Instead of using the "pretract" there is a postblock called "protretinc",... it resets the C axis rev counter in the post. There is already logic in the post block that will output the M11 / M13, you may also want to shut down what was added in "pretract"

 

protretinc #Reset the C axis revolution counter

if frc_cinit,

[

p_abs = zero

p_inc = zero

s_abs = zero

s_inc = zero

pset_dlt_to_abs

# if use_clamp, #Unlock rotary axis <<<< you will need to remove the pound signs from these lines

# [

# p_lock = zero

# s_lock = zero

# pbld, n$, s_slock, e$

# pbld, n$, s_plock, e$

# ]

# pbld, n$, *sg28, p_out, s_out, e$ <<<< to here

p_wnd_ang = zero

s_wnd_ang = zero

!p_wnd_ang, !s_wnd_ang

]

 

##### Stop custom changes #####

Thank you. I'll try this today.

Hi CJep. Thanks for your help. I'm using "protretinc" it works good. The problem I have now is that when I'm machining in different plane, it looks like it's clamping and unclamping in every 1/2 degree until reaches to next position. This is only happening when I post all my operetions. If I post different operations from same plane it works fine. below you see what is happening. This has nothing to do with the changes I did in "protretinc".

Thanks.
