General Mach Discussion / Re: Circular pocket shout out

« on: June 12, 2006, 06:14:27 PM »

Doing a normal circle you only have 4 direction changes,  with a spiral pocket this is multiplied by the number of arcs cut, so the backlash is highlighted.  Also the cutter can be pulling and pushing the table at varying amounts as the circle gets bigger.

Hi Keith,

The flat could be cutter flex or backlash.

For your information :-

Circular holes can be cut very easy with the following commands.

Hole is at X0 Y0 with a radius of 1.000"

G00 X0 Y0                   (move to start)
Z-.1                            (move to Z depth)
G01 G41 X1. D(offset number for tool rad) F5. (move X pos+radius and use compensation)
G03 I-1.                      (do a full circle cut)
G00 G40 X0 Z1.           (rapid to X start and Z safe)
M30                           (end)

General Mach Discussion / Re: Limits HELP!!!!!!!!!!!!!!!

« on: June 11, 2006, 08:06:27 AM »

Hi,

normally the Y axis zero point is to the front of the machine and the X is with the table to its left most point.

If you go to Homing/Limits in the config menu you can reverse the homing direction and set the G28 values.

If you set G28 as X0, Y0, Z0 you then use G54 to position your work zero, this is on offset form zero return to the zero point on the job.

E.g. If you clock a hole on a part and look at the Machine DRO and it says X-5.5000 and Y-3.000 these are the values you enter into G54 offset.

I hope this helps, come back for more if not.

I came across this today, thought it may be of interest to somebody.

It converts images to CAD.

I will be there too.  I can't stand not knowing what went on.

Benny why not use your new advert block to ask for pictures, video etc.

Don't know who will pay the $1000.00 per week though

I would have thought it should look more like this

But I may be wrong as I use VB 2005

G-Code, CAD, and CAM discussions / Polite request

« on: June 06, 2006, 02:57:20 PM »

Dear Brian & Art,

would it be possible to add U,V and W to Mach3 turn, the X,Y and Z incremental moves are a major part of turning code.  Also could we have I,K and R automatic chamfer and radius.

This may seem petty but Mach3 mill is very comprehensive and turn seems to get the raw end of the deal.

Thanks

Graham.
