Thread: What Did You Do Today 2021
12/04/2021 00:20:46
Posted by John Haine on 10/04/2021 13:02:58:

Finally connected up the 4th axis drive on my Novamill so I can experiment with some helical milling.


That method of drive coupled with the stepper holding power should resist any movement under cutting forces without clamping the D/H spindle.
That machine looks new still !!!


Thread: An explanation of CNC machining terms

If you are using Meshcam addon for Alibre if you Export your 3D model as a step. file to a folder with Fusion running you can Import the same step. file and using Manufacture produce the CAM and postprocess to suit your machine.

Stuart, looks like you got the answer on the iO Colchester Group ?


Thread: DeskCNC resurrection - USB to serial adapter
09/04/2021 15:17:26

Thanks for the advice the adapter works OK, this topic often arises on the Emco and Denford forums when using old machines that need the Serial link for communications.

Here's a link to 1 of many you tube videos that may be helpful.



Thread: Hangar door suspension
06/04/2021 22:01:56

On occasions when the top support structure proves inadequate to support the weight of the door it is jacked up to provide floor track clearance and a wheel is fitted at each end of the door on the free side if double doors are fitted.

You may need a 2800 rpm motor on the jig borer to get speeds suitable for small cutters, .37kW output minimum.

For the wheel cutting engine perhaps a 1450 rpm motor will suffice, as suggested 300W output.


Thread: Warco 712 Bandsaw
05/04/2021 09:55:32

Most likely Richard also wants the extra capacity (180x300) offered by the 712, but if not like many who have commented I would certainly look at improving the performance of the existing machine before going ahead with another purchase.

Not good to export and reimport as that only brings the part back and you have to do the CAM all over again.

If you can't edit a file losing the CAM by Exporting and Importing is a small price to pay, as you say Jason only 10 minutes to do the CAM from the model.


03/04/2021 10:43:50

If you open the Model and EXPORT a stp file to your computer and save under another name then IMPORT new named stp file it may show the original sketches, if not with the model loaded you can generate any number of new drawings from the model.


Thread: CNC - What's the Problem?
01/04/2021 11:44:44

Nigel, a bit more of an insight:

I use a 1985 Emco 5cnc lathe and an Emco F1 cnc mill, both are programmed by manual G&M code entry, either at the machine control pad or via an RS232 link to a computer.
On the lathe a single line of code will face the end of a bar, another line will turn any amount off the bar at the chosen depth per pass and selected cutting feedrate.
Threading either metric or inch is also a single line entry for threads from 0.25 to 2mm.
To part the work off also only needs 1 line of code.
There are 2 methods of programming, Absolute or Incremental that is used below.
In the code below the bar is 16mm diameter extending 25mm from the chuck jaws.
The RH cutting tool is positioned at 16mm diameter and the end of the bar.
No decimal points are used so 800 = 8.00mm and 50 = 0.50mm
After each cycle the tool returns to the cycle start position.
g code sample.jpg

Line 01 faces off .50mm for 8mm depth at 100 mm/min feedrate.
Cutting point of tool now 0.50mm from end of bar.
Line 02 turns 6mm off (12mm off diam) for 21.50mm length at 100mm/min
Line 03 Toolchange to threading tool, X&Z dimensions are the tool offsets
Line 04 Threading cycle .50mm depth of thread for 19.50mm at 1.0mm pitch

The 21.5 and 19.5mm dimensions are because the cycle starts 0,5mm from the end of bar.

It is only a 2 minute job to enter such a program at the machine control, takes less time than a computer takes to start and load the CAD.CAM program never mind about doing a sketch, converting to a model then completing the Manufacturing set-up then finally using a Postprocessor to output the machine code.
This is only true for simple turning and milling operations, for more complicated work and 3D milling CAD/CAM wins hands down, unfortunately such programs cannot be used by my old Emco machines without retrofitting, I have been messing with a lathe conversion and have CAD/CAM facility on that using Mach3.

Are you certain the existing motor is not dual voltage 380/220v, to be sure check inside the terminal box for number of connections.

Posted by William Ayerst on 29/03/2021 16:48:50:

Am I right in thinking the shed should in theory already be on a concrete slab? So pouring another 3" or so to replace a boarded floor should in theory be more than stable enough for a mill?


Much depends on the soil in your area and of course was the base prepared before the shed was erected.

IMO you need 100mm of hoggin compacted by vibrating below a concrete slab of 100mm thickness to provide a suitable base for your machines, you may want to consider a steel mat insert for added security.

Thread: Denford Starturn 8 Lathe Docs & Software needed.
27/03/2021 17:55:16

Just because the boards have a different appearance they can still use the same software, you won't know until you download and attempt to run the machine.

If you use the link it takes you to a copy of the software to run your machine, if you want an older version I can send that via email if you pm me your email address.

Michael, strange the link got corrupted, thanks for re-posting a working link. Same happened again when using the LINK menu, link when posted didn't work.

Check which mode, Diameter or Radius, the program is written in matches the setting in Mach.

When you select the tool use the Setup option in the Tool menu to orientate the tool correctly, you can Edit the tool after selection if you need to change anything.

Also when completing the work setup you can Flip the WCS direction for Z and X axis.
