Fanuc 31i horizontal post processor request

[britovsekmatic128]

Hello,

My company is planning on buying fusion 360 after i've been nagging them for a while.

My question is, will the generic fanuc post output work with b axis?

If not could some help me with editing an existing post? I have literally zero experience with posts and coding.

Thanks!

Hi @britovsekmatic128 ,

Yes. You can download Fanuc Milling generic post-processor from here and make the following changes on your post-processor.

Open your Postprocessor in any editor or VS code & search for function defineMachine() . You will find the following codes in your post-processor.

Step 1 : Now change it from this...

function defineMachine() {
  var useTCP = true;
  if (true) { // note: setup your machine here
    var aAxis = createAxis({coordinate:0, table:true, axis:[1, 0, 0], cyclic:true,range:[-90, 90], preference:0, tcp:useTCP});
    var cAxis = createAxis({coordinate:2, table:true, axis:[0, 0, 1], cyclic:true, tcp:useTCP});

to this

function defineMachine() {
  var useTCP = false; // set it true if machine supports TCP 
  if (true) { // note: setup your machine here
    var bAxis = createAxis({coordinate:1, table:true, axis:[0, 1, 0], cyclic:true, preference:0, tcp:useTCP});
   // var cAxis = createAxis({coordinate:2, table:true, axis:[0, 0, 1], cyclic:true, tcp:useTCP});
    machineConfiguration = new MachineConfiguration(bAxis); // set B axis

Step : 2 Set the following variable to false.

From true to 

var useMultiAxisFeatures = true;

false

var useMultiAxisFeatures = false; // set it to false 

Now save the post modification and test it carefully.

Thanks @KrupalVala 

Made the changes that you posted and it seems that it outputs the correct code,
even changed the coolant calls!
Should i be worriend about the G19 code that it posts or is that only for the lead in/lead out(for facing)?
Going to try it out tomorrow by cutting some air.

Thanks again.

That's most likely there because you have a vertical lead in radius value. I usually set that to 0.

[britovsekmatic128]

You're right, i disabled the vertical lead-in and the program plunges straight to depth without G19.
What is the idea behind vertical lead-in?Less force on the screwballs/axes?

@KrupalValaFollow up question if i may?

Is there a way to add G code before every tool call and behind tool call the Workoff set that is being used(G54)?

Example:

(Face mill D125);
G90 G94 G80 G40 G49;
T1 M6;
G54.1 P016;

Thanks!

Hi @britovsekmatic128 ,

Add following code before the insert Tool Call

    gFeedModeModal.reset();
    gAbsIncModal.reset();
    writeBlock(gAbsIncModal.format(90), gFeedModeModal.format(getProperty("useG95") ? 95 : 94), gFormat.format(49), gFormat.format(40));

    skipBlock = !insertToolCall;
    writeBlock("T" + toolFormat.format(tool.number), mFormat.format(6));

 You will get following output.

N145 G90 G94 G49 G40
N150 T2 M06
N155 S5000 M03
N160 G54​

Thanks,

Thank you @KrupalVala

I downloaded the .cps file and when trying to change "var useMultiAxisFeatures = false; // set it to false" and I can't find that variable

[KrupalVala]

Hi @marcelo_merindol ,

In the latest PostProcessor, Please search for the following setting and set it to false. When it is disabled, the rotary axes will be output for 3+2 operations and the output coordinates could be adjusted for the tables/heads based on the TCP setting for each axis.

useTiltedWorkplane    : false, // specifies that tilted workplanes should be used (ie. G68.2, G254, PLANE SPATIAL, CYCLE800)

Thanks,
