General Mach Discussion / Re: Determing THe X and Y direction of the workpiece so it can be in any direction

« on: November 10, 2015, 09:19:47 AM »

hi,

G68 is used in the Gcode to change in XY plane, but it is not what i mean. I mean i want to put a plate on the table for example 15 degrees out of parrallel with the Y axis and than teach the machine that the Y axis is now no longer at 0 degrees but it will be a diagonal line on the bed.

So when i run a program, it will always take into account whezn moving along a same X coordinate that the machine will have to move diagonally as the workpiece is not straight with the Y axis.

General Mach Discussion / Determing THe X and Y direction of the workpiece so it can be in any direction

« on: November 10, 2015, 09:01:03 AM »

Hi all,


I have a question, does mach3 support the possibility to determine the edges of the workpiece so it can itself determine the X direction and the Y direction to work on rather than the machines X and Y fixed directions.

I have seen other machines who will touch an edge of a workpiece on 2 different points like 50 cm apart and thus the machine knows that this is the X axis and than they touch the other side of the workpiece on 2 different locations and thus that is set as the Y direction.

Than they load in the Gcode and the machine does it job taking into account that the workpiece is not 100% parrallel with the X and Y direction of the machine.

This means you can put a plate not parallel to X and Y on the table and still get the machine to work as if it was perfectly parrallel.

I think it should be able as this is like a problem everybody would face, so i hope this has a simple answer to it and i really hope mach3 is able to do this.

THanks for any help,

Stephane

Ok but which 5 axis postprocessor i start with from solidcam to mach3?

Hope u have an idea

OK. Thanks for this answer. But the cam is doing the work. I work with solidcam but it is the transpolation in the postprocessor that gives the problem.

Anyone has tips or tricks how to program this in the postprocessor when the cam is working with different coordinate systems???

I really hope so

G-Code, CAD, and CAM discussions / Rotate the WCS around the Y axis

« on: October 26, 2015, 06:04:25 PM »

Hello everyone,

I am breaking my head here.

I want to rotate the entire coordinate system around the Y axis. Like the righthand XYZ and than turn 90 degrees CCW. This is to mill side pockets. I have a rotary on the spindle so the rotary is turning parallel to the Y axis.

How do i implement this in Gcode. I was looking at G68 but that only allows me to rotate in the XY plane and i want to be drilling in the YZ plane.

I think a lot of people have this problem though, as i need to figure this out so i can implement in postprocessor.

Basically i would like to know if there is Gcode that will make this easier, rather than having to calculate every single position of the machine to drill the side pockets ( taking into account that X becomes Z and thus headbreakers ) . As it needs to calculate based upon another coordinate system set in the Cam software, this will be different everytime depending on the piece. Very difficult to get the correct coordinates.

Any help pleassseeee THX

Hello,


He is asking me for the Zero transformation points between the different coordinate systems in mach3

"Not good transformation zero points. I, I gotta find it somewhere example. "

Anyone knows.

Thx

Hello everyone, since shortly I am part of the mach3 milling community and happy about this. 

Now my problem is following. Someone is writing me a postprocessor but his english is the worst ever. So he asks me for the following.

"For your Mach3 need parameters indexed. It should set the parameters for indexed.
I need example NC.Program - From supplier Mach3 get."

Does anyone understand what the hell he would like me to send him, cause I don't have a clue.

Postpro is for solidcam. And it seems he programmed for simultaneously which ment I couldn't set 3 coordinate systems to side drill with a rotary attachment on the spindle. So he needs to change it to indexed. Whatever that may mean... . anyway this is what he send me, so please help what do I sooooo

Thanks for your help.
