Wow !

I can't wait to see pictures of this machine when you build it. Please post pictures.

Good luck,

Hi John,

Just out of curiosity, what sort of weight do you expect to carry on this slide ?.

FAQs / Re: Gear cutting

« on: December 11, 2008, 07:03:43 AM »

Hi Sivtek,

Yes sir, I would use the DRO scale function to adjust the depth. (Type in 1.100 and press return as an example to increase the depth by 10%).
I have not used the 'gear cutting wizard' as I would, in preference, use a gear cutting tool (gear tooth profile) approaching the work from the side, as shown in the earlier diagram - so I can not be much help here.

Regards, Tweakie.

Hi Sivtec,

What I would do is this - Insert a shim between the cutter and work and bring the axis into contact, the shim will be vertical when the height is correct, zero the Z Axis. Now with a cigarette paper on the work and cutter running approach the work (X or Y Axis - which ever you are using for depth of cut) until the paper is touched, zero this axis.
Cut the first tooth and inspect, if necessary increase the depth using the axis scale function ( scale 1.100 for example) and when it looks correct then cut the remainder.

I apologize if this is too basic.

Regards, Tweakie.

Hi,

If it is of any help to you - I have a router which uses linear rails and ballscrews which runs perfectly (during the winter) at 5 deg C no problems. My newly acquired mill which has iron ways and ball screws does require a couple of traverses on each axis before use at this temperature and I have put this down to the lack  of viscosity in the oil on the ways.

Hi Guys,

Something you may find useful when setting up a machine for the first time and there is no response is to check that Mach is actually sending data to the parallel port. The port itself can be monitored using Fred Bulbacks nifty little monitor 'Parmon'. This can be downloaded from the following link.

Hi Civtec,

Are you profile cutting the gears or are you tooth cutting using a forth axis perhaps ?.

Hi Guys,

I would love to attend but the seminar is a little too far away for me to travel but I wish you all a good time.

Merry Christmas and a Happy New Year to you all.
