TWEEKIE, Question on the E1p0(;-)   How are you generating your Gcode for laser???

WOWZER Tweakie, I don't often drool over organic art but I think I feel a new machine in the near future.  How fast does the Machine NEED to be to be effective with Laser cutting.

Got any Plans or info on the laser part. No problem on the machine build but that last thing I played with light wise was a flashlight.

Do you use mirrors or perhaps a fiberoptic system?  Spill the beans (;-)

Steve the way we do it here is generate the lobe profile. Load the blank into the 4th between centers. Rotate to a start point on the blank. Cut the profile onto the first lobe. Move over in X to the next lobe rotate the cam to orientate the next lobe center and cut that lobe then on to the next. Once you start it is very easy to index the separate lobes at the proper lobe centers. IF you want a split profile just substitute the intake profile for intakes and exhaust for exhaust.



I am sure your process works for you but 47 cuts per lobe?? that is a lot of setup(;-)

Keep us up to date on your project.  Mini's look cool but I will stick with the big boys

Ed does have a good Idea to do the lobes and then silver soldered or braze them to the shaft them to the shaft. Without a 4th that would be a good option (;-)

(;-) The design prevents the lifter from digging in. Your lobe must be correctly designed to run with your lifter. The curve is the actual ramp of the lobe. You can run right up to the edge of the lifter with the ramp design without problems. Over at the Andrews cam software you can download a free simple design program to design the lobe to fit properly. Also the trick is to design a constant velocity lobe but that is another story.

Steve we have run flat lobed cams and flat lifters well over 11k rpms in race engines.

Steve do you have a 4th axis for your mill?  Cranks and Cams are fairly easy with a 4th. You can turn the blanks in the lathe to rough out and do all the offset work with the 4th. In bigger stuf we used round for the blanks to save time then did all the work on the mill and 4th

You can always light the torch manually(;-) the OXY/Fuel valves can be M8 on M9 off THe Oxycut valve can be M3 on M5 off.

Rene on the standard screenset it is on the settings page (the green one) top right hand corner it says Rotation Radius

In gen config you need to Check "Home Slave axis with master " that way the A slave will home with the Y master axis and use the Y switch.
