G-Code, CAD, and CAM discussions / Re: ACAD import points to a drawing

« on: June 11, 2011, 10:42:59 AM »

(;-) That is one of the reasons to be able to SEE the profile AN anomoly sticks out like sore thumb.

That looks great.  Converting to polylines would be helpful I could always explode it out if needed.  Is it possible to include a center point for the base circle ?  WouldI just add in a zero lift data point?

NOW the next question. AFTER I have smoothed out any quircks can I do curve fitting where it will work???   CAn you take the finish product back out to points or possible simple GcodeGcode??

NOT an Acad wizz, (;-) TP

This is an example of the basic motion AND the profile based on the data. I can output the points file from EXCELL in about any manner or order you require.

A basic probed point file is 3600 an advanced profile may be up to 360,000 points

ACtually I want to place the points then do a smoothing of the shape.Then output that shape in Gcode form as X (linear) and A axis (polar) being a rotary axis

But I will take anything I can get (;-) This is for a CNC cam grinder project I am working on.

The first column is the height data is is based from the center of the base circle.

The second column is the polar positions in deg. At each polar point the height extends from the center.

HI GERRY, I can put the points in any format. I use ACAD2000.

You could wire the alarm relay with an inverse function.  When the relay (normally closed) turns OFF the allarm comes on.

Justa thought, (;-) TP

General Mach Discussion / Re: Help with converting a Supermax mill to mach

You probably already have working drives and power supply. You just need a controller that can output the Analog signal and receive the encoder inputs. I would recomend the KFLOP controller. It already has the MACH interface for it.

In a nutshell you would remove the old controller leaving the power supplies and drives and any relays that drive the coolant, spindle,et

Then wire in the KFLOP to the the drives and bring back the encoders to the KFLOP. That would get you moving on the axis.

Next you would wire in the controls for the spindle and coolant,etc.

I would contact TOM at teh Kflop site he is VERY knowledgeable in retrofits to the KFLOP system.

BUT AGAIN add the cost up carefully used VWC s with tool changers are CHEAP these days.

DOes anyone know how to bring in points to a drawing in ACAD ?

What I have is a set of points that represents a cam lobe. The points consist of height around a 360deg circle (polar)

The height represents the profile of the lobe around a base circle.

General Mach Discussion / Program A axis to rotate as a Spindle

« on: June 10, 2011, 01:32:51 PM »

It is not possible using MACH in the NORMAL manner.

HOWEVER  IF you had a "manual spindle control " ( you turn it on/off by hand) you could set up the A axis to be run AS a spindle with step direction control. Speeds would be limited though.

Just a thought, (;-) TP
