Help Needed with 3+2 Programming

Anonymous — Mon, 01 Apr 2019 19:29:57 GMT

Hello Everyone,

I'm in need of some assistance with a part that I'm programming. We currently have an Okuma Milling machine with a 5-axis rotary table bolted on to the machine (The center of the 5-axis at B90 is 5 inches from the table of the machine) I am trying to drill a hole a create a flat face on a part and I don't even know where to start. I tried doing a drilling op with the WCS perpendicular to the hole and got a failed post. I don't know how to make fusion know where my part is once it's tilted. I am pretty good at 3-axis programming but I've never delved into 3+2.

Here's a picture of the part, not sure why I can't attach the fusion file.

You can go File>Export to get your file to attache. I tried your link and it gave me a file that fusion could not open.

When you go to attach a file it needs the links broken otherwise it comes in as a .f3z what needs to be uploaded not just opened,

A good way to do it is to do a save as then brake link then attach that file this gives you a .f3d what can just be opened.

What post are you using.

If you are using the default post A and C axis is turned off a change needs to be done to the post to get what you want.

This bit here

function onOpen() {

if (false) { // note: setup your machine here
var aAxis = createAxis({coordinate:0, table:true, axis:[1, 0, 0], range:[-110, 20], preference:0});
var cAxis = createAxis({coordinate:2, table:true, axis:[0, 0, 1], range:[-360, 360], preference:0});
machineConfiguration = new MachineConfiguration(aAxis, cAxis);

Change to this

function onOpen() {

if (true) { // note: setup your machine here
var aAxis = createAxis({coordinate:0, table:true, axis:[1, 0, 0], range:[-110, 20], preference:0});
var cAxis = createAxis({coordinate:2, table:true, axis:[0, 0, 1], range:[-360, 360], preference:0});
machineConfiguration = new MachineConfiguration(aAxis, cAxis);

It is online 194 in the post

One other thing you did not have the setup down correctly you did not set the WSC if at any time you move the model even by mistake the cam output will be wrong and it will crash.
