Hi, is there any way how to change transitions between cuts in Surface high speed area roughing? How to make transitions smoother (red lines) This is someties causing undercuts because of tool vibrations.

Thanks

Best way: Create 2D contour toolpath with compensation off - center of tool, lead in/out off. Set tolerance and arc filter. Then save toolpath geometry into any level and delete vertical lines (if there any). 

Hi,

you can do it via post modification. I created this into my post, little modification and it can be applied on your case.

http://www.emastercam.com/board/topic/87537-how-to-filter-duplicates-from-buffer/

Just add simple condition, when parameter 15346 = 3, than pop up window to warn programmer....

i just added new postblock to warn programmer when he uses different tool compensation on same tool. If i have already this information stored in buffer, why not to use them :-) It only compare wear vs. control/rev.wear. Not control vs.rev.wear

ptlkontrola  #controls if wear / (control | reverse wear) is used with same tool

got it.... :-)

Hi,

i have two buffers and need to filter duplicates from them.

For example Buffer 1:

20 20 20 20 24 18 18 20

and buffer 2:

2 0 2 0 0 2 0 0

I want to filter from buffer 1 only values that match "2" in buffer 2. In this case it is only  numbers 20 and 18 and want to have theese numbers only once in buffer 3.

so i wrote this:

    zero = wbuf(3,wc3)  # put 0 to buffer 3, no null size buffer
     size1 = rbuf(1, 0)
    while rc1 <= size1,
  [
       toolnumber = rbuf(1, rc1)
    size2 = rbuf(2, 0)
    toolcomp = rbuf(2, rc2)
    if toolcomp = 2,
    rc3 = 1
    size3 = rbuf(3,0)
    while rc3 <= size3,
    [
        toolselect = rbuf(3,rc3)
        if toolnumber <> toolselect,
        toolnumber = wbuf(3,wc3)
    
      ]
    ]

and result of this in buffer 3 is : 0 20 20 18 18 18

I think, this reads values from buffer 1 and 2, if it match condition "2" than it scan buffer 3 if toolnumber is present, if not it write it to buffer 3 and than "rewind" buffer 3 (rc3 = 1)

What is wrong with this code or am i miss something?

Thanks for help.

I am very experienced using WCS and modelling. Also i programmed 3+2 for years, very variable jobs, so not only  copy and paste. But in september we went to five axis and it was completly new world. Especially Tool axis control page :-) It takes me about 1 month to learn what which toolpath do and how and when to use it. Hardest part for me is postprocessor and machine simulation, i am still arguing with reseller about that.

But i'm still cautious and paste program pause into g code before five axis part of program :-) I am still learning.

c9k is only defied variable. c9k=9999

thanks

i tried to set condition rc2 = size2 inside second loop which should stop looping

    if stplnam <> swcsnam, rc2 = rbuf(2, 0)

but this doesn't work :-(

Finally i programmed this:

#buffer definition
stplnam
size2 : 0
rc2 : 1
wc2 : 1
fbuf 2 0 80 0

swcsnam
size3 : 0
rc3 : 1
wc3 : 1
fbuf 3 0 80 0

pwrttparam$ #pre read routine

      if prmcode$ = 20014, sparameter$ = wbuf(3, wc3) #store WCS name to buffer 3
      if prmcode$ = 20012, sparameter$ = wbuf(2, wc2) #store T-plane name to buffer 2

pwcscheck # postblock to read and compare WCS - T-plane

    size2 = rbuf(2, 0)
    while rc2 <= size2,
    [
       stplnam = rbuf(2, rc2)
        size3 = rbuf(3, 0)
        while rc3 <= size3,
        [
        swcsnam = rbuf(3, rc3)
        ]
    if stplnam <> swcsnam, result = mprint("WCS - TPlane ARE DIFFERENT!!!")
        ]

psof$            #Start of file for non-zero tool number

 pwcscheck

...

...

It looks like it works, but i have another question:

is it possible to stop while loop after first postitive result? Because at this moment it gives me as many pop-up windows as many differences in plane names.

Thanks

I would like to warn programmer, that WCS and T-plane are different, so i added this into my post:

"string definition"

s_wcsnam
s_tplnam
 

and in pparameter$  section

    if prmcode$ = 20012, s_tplnam = sparameter$
    if prmcode$ = 20014, s_wcsnam = sparameter$
      [
         if s_tplnam <> s_wcsnam, mprint("WCS-TPlane !!!)

      ]

but i get this error:

PST LINE (914) - The post block output type processing has failed!, , Label has not been defined[32]
PST LINE (914) - The post block output type processing has failed!, , Illegal character(s) encountered
PST LINE (914) - The post block output type processing has failed!, , Label was expected but was not found[51], Illegal character(s) encountered

I think that boolean <> is allowed for strings and result is 0 or 1. I tried many options how to fix this, but it still doesnt work. Pleas, can you help me?

And the next level is how to capture WCS origin coordinates and compare them to warn programmer.

These values are in OP_VIEW003 parameter 15366-15368, but i dont have this output in NCI.

Any Idea?

Thanks,

Smrk

Hi,

i want to generate total maximum/minimum coordinates of whole program, so i added this into my post:

#buffer 2 min/max
b2_xmin : 0
b2_xmax : 0
b2_ymin : 0
b2_ymax : 0
b2_zmin : 0
b2_zmax : 0
size2 : 0
rc2 : 2
wc2 : 1
fbuf 2 0 3 0 0

------------------------

# variable def
fmt "" 2 x_tmin     #min X
fmt "" 2 x_tmax     #max X
fmt "" 2 y_tmin     #minY
fmt "" 2 y_tmax     #max Y
fmt "" 2 z_tmin     #min Z
fmt "" 2 z_tmax     #max Z

-------------------------

# in psof section:

      ptravel
      pwritbuf2
      ";(","X-MIN= ",*x_tmin,")",e$
      ";(","X-MAX= ",*x_tmax,")",e$
      ";(","Y-MIN= ",*y_tmin,")",e$
      ";(","Y-MAX= ",*y_tmax,")",e$
      ";(","Z-MIN= ",*z_tmin,")",e$
      ";(","Z-MAX= ",*z_tmax,")",e$

ptravel
    if x_min$ < x_tmin, x_tmin = x_min$
    if x_max$ > x_tmax, x_tmax = x_max$
    if y_min$ < y_tmin, y_tmin = y_min$
    if y_max$ > y_tmax, y_tmax = y_max$
    if z_min$ < z_tmin, z_tmin = z_min$
    if z_max$ > z_tmax, z_tmax = z_max$

# buffer read write
pwritbuf2
     b2_xmin = x_min$
    b2_xmax = x_max$
    b2_ymin = y_min$
    b2_ymax = y_max$
    b2_zmin = z_min$
    b2_zmax = z_max$

and the result is this:

It looks exactly what i want, but i would like to ask you, if this code is without any hidden bug.

Hi,

i wonder how to create machine definition for machine simulation. I have solid model.

In machine simulation toolbar is "machine conversion" but after clicking to this button i have pop-up window " Please fill the path in where machine to be exported in IOF_machine_path.ini from user\Documents\my mcamx "

I dont have this file in that folder.

Thanks for help

Do the same with surface finish toolpath. Video in flash in attachment.

2014-05-02_0718.zip

So you can select "update tool" in pop-up window after editing tool. My problem is, that after tool edit i have two same tools - not original and new one with different diameter.

Bug description:

When a tool is used by multiple operations, double clicking, editing, and electing to create a new tool is no longer editing the original tool and then not updating the original toolpath.

I think, this bug is not fixed in MU2. I still have this problem.

not even in private message? I am asking because when i ask my reseller first time for price, he told me something and second time ho told me almost double than before.

Please, can you tell me, what is the price of multiaxis licence and Heidenhain 5 axis post processor? I am just curious, what prices are in other countries (resellers)

in our company (we have "only" two seats of Mastercam) i set up directly into postprocessor line "programmed by: ..." on each computer. But this solution doesnt cover changes in models etc, but we can find responsible person for NC programs.

inkscape or mastercam c-hook rast2vec or upload that file somewhere, i can convert it for you

I did some tests and the winner is.... "surface finish contour" operation

In example file are ops 1-7 (7th is finish contour)

Three stock model ops:

8 - stock as bounding box, selected operations 1-6 (without surface finish) - this takes aprox 19 sec to calculate - so no problem

9 and 10 have selected all ops as source operations - and it freezes during calculation

TK-TEST.MCX-7

I have Dell precision T1650 workstation with Nvidia Quadro 2000, i7-3770 processor.

I suspect Windows 7 updates to do that, because i dont have this problem month ago
