The postprocessor does not fulfill the fusio360 conditions (CYCLE800)

[kpekepc5]

Good afternoon. There was a problem in the cycle 800 postprocessor. The post processor works correctly when using the "B" or "CB" axes together. The problem is that when the tool is oriented around the Z axis, the table in the program does not rotate. This is due to the absence of CYCLE800 in the generated code. Attached screenshots and the code generated by the postprocessor

Hi @kpekepc5 

What post are using if you are using siemens 840d post then you should get expected output

[kpekepc5]

I use the post 840D, but there could have been changes made before me. Currently I'm trying to figure out the problem, I can't find a function that is responsible for turning the axis under similar conditions.

[boopathi.sivakumar]

This is the function which is taking care of rotating around Z axis

[kpekepc5]

it looks different to me. 😥

I would suggest to use the latest post. recently we had added improvements to the post.

[kpekepc5]

The problem remains. I used the new postprocessor without changes, the result is the same. Cycle800 is missing from the generated program.

[kpekepc5]

there is an opinion that FUSION360 itself does not provide the necessary parameter for the reversal, it simply converts the orientation of the tool and executes the program without using axis rotation.

[boopathi.sivakumar]

Hi @kpekepc5 

you need to define the machine kinematics into the post either via machine configuration or hard coding the kinematics in the defineMachine() function in post.

[kpekepc5]

The situation is the same. When the tool is oriented for the "B" axis, everything is fine, but the "C" axis does not lend itself to physical rotation.

[boopathi.sivakumar]

Hi,
I can able to get the expected results


Where did you set the machine kinematics?
Are you defining it in the post? or using machine configuration?

[kpekepc5]

[boopathi.sivakumar]

I feel still you are using the older post. Kindly share the older post and newer post you are using

[kpekepc5]

Right. Sorry, my head is too overloaded.

function defineMachine() {

  var useTCP = true;

  if (false) { // note: setup your machine here

    var bAxis = createAxis({coordinate:1, table:true, axis:[0, 1, 0], range:[-10, 120], preference:1, tcp:useTCP});

    var cAxis = createAxis({coordinate:2, table:true, axis:[0, 0, 1], range:[-360, 360], preference:0, tcp:useTCP});

    machineConfiguration = new MachineConfiguration(bAxis, cAxis);

    setMachineConfiguration(machineConfiguration);

    if (receivedMachineConfiguration) {

      warning(localize("The provided CAM machine configuration is overwritten by the postprocessor."));

      receivedMachineConfiguration = false; // CAM provided machine configuration is overwritten

    }

  }

I checked, the result has not changed.

[boopathi.sivakumar · Accepted solution]

instead of false you have to set this as true as shown below

 if (true) { // note: setup your machine here

[kpekepc5]

Ouch.... good! it worked!

[kpekepc5]

Ouch.... good! it worked! Thank you very much! I apologize for my ignorance.

Added a block for convenience, so that you can disable and enable the function.

cycle800Rotation: {

    title      : "CYCLE800 On/Off",

    description: "On or Off CYCLE800.",

    group      : "multiAxis",

    type       : "boolean",

    value      : false,

    scope      : "post"

  },

.................................

function defineMachine() {

  var useTCP = true;

  if (getProperty("cycle800Rotation")) { // note: setup your machine here

    var bAxis = createAxis({coordinate:1, table:true, axis:[0, 1, 0], range:[-10, 120], preference:1, tcp:useTCP});

    var cAxis = createAxis({coordinate:2, table:true, axis:[0, 0, 1], range:[-360, 360], preference:0, tcp:useTCP});

    machineConfiguration = new MachineConfiguration(bAxis, cAxis);
