multi-part programming

Anonymous — Thu, 12 Oct 2017 15:50:43 GMT

Dear all,

I would like to get your help, so I can change one of my work processes.

Currently the programming of the pieces in all positions, roughing and finishing is done 100% with automatic processes, but one session is used for each piece.

In the machine are placed several pieces at once, in which the machining position is defined by the machine operator.

My goal is to calculate (one session) for several pieces at the same time.

I do not know how to resolve the following points

1) Positioning of parts on the powermill (no interactivity)
2) After setting position, how to rotate the part over the point itself.

My working rule is with Z zero at the base of the part, so the rotation of the parts is always in the X-axis direction.

Thank you for your help.

Is the operator using G54-G56 for setup??

Hi Pijetro,

No, shift points are used.

Okay...

So I'll assume that each part is movable on the machine, and each part can be picked up and moved independently, and not related to one another.

So typically, what I'd do in a scenario like this, is create a workplane for each pickup point...Each workplane would have separate NC outputs for each part..

I go into my Fixture offets within the NC output, and assign separate pickup points (in my case, G54-G59)..

Of course, you can assign Macro variables here.

But I'm not 100% sure about your needs...

Hi Pijetro,

"So I'll assume that each part is movable on the machine, and each part can be picked up and moved independently, and not related to one another." - YES

"So typically, what I'd do in a scenario like this, is create a workplane for each pickup point...Each workplane would have separate NC outputs for each part..

I go into my Fixture offets within the NC output, and assign separate pickup points (in my case, G54-G59).." - This is what I want to avoid ...

On the machine I already have fixed points. I want to use only one orientation point (G54) and the position of the parts in the machine must be done according to the PM session.

My greatest difficulty is to prepare the session in the PM (position the pieces) and how to rotate the pieces over the "center" itself so that you can rotate the processes on the second side. Programming of individual model the rotation is done on the axis (X), but for several parts, when rotating the axis, the models are in inverted position.

There is an easy way to move the parts to the correct position.

You have a table model, with the target points (I suppose, there are workplanes defined.)

You have a method (automatic or not ), to set up a workplane relative to the work part. So what You need to do is to move the part between the two workplanes.

On the model transform form, there is a button to move the part to the global csys origin and orientation,

TRANSFORM TYPE WORLD TRANSFORM MODEL "Yourmodel"

and an other one, to move the model to the active csys.

TRANSFORM TYPE WORKPLANE TRANSFORM MODEL "Yourmodel"

So first activate the second workplane (what is relative to the part), and move the part to the global.

Then activate the target workplane, and move the part to the active workplane

Dear Kukelyk,

Thank you very much, your help was very helpful.

How do you suggest me to ration the models to the second programming position?

Is there any way to interconnect a particular work plan with a model? The work plans can have fixed names, but the models do not have a fixed name, it is possible to connect the first work plan with the first model, second work plane with the second model, etc ...

Thank You

So when You have Your parts in the first position, You should have to set up the second position's reference position in the current part location. After that You can use the above positioning method. See image: You already have the orange coordinate-systems, You need to define the blue one.

Hello,

After analyzing and understanding this procedure, this is my right way.

Thank you so much!
