Re: [Emc-users] OT - help identifying machine in a collage
To follow up on this off-topic thread, my librarian friend contacted the curator of the museum and got the following response about the machine in this collage http://www.flickr.com/photos/60584010@N00/4304142095/ Quoting Davor Kernel : Hello! About machine in the middle of collage of Černigoj: After the conviction of the Honorable colleague, dr. Vižintin (University of Ljubljana, Faculty of Mechanical Engineering), this is a portable winch, which can be used for lifting loads in the construction, forestry or elsewhere. The winch can have inner gearwheel or belt transmision. The picture: lower, brake shaft, that juts out, is prepared to fix somekind of winding up drum, small handle in the middle is used as a handle for hand or manual drive. Regarding to the year (1925), Černigoj probably wanted to show utility for the manipulation or supply of apartments in higher floors in the neighbourhood or even on the streets.

Re: [Emc-users] Fanuc tool changes - was Ideal Tool Table
Andy, I can imagine that a format like T10.12 would work (tool 10, offset 12). What I think one really wants is to have code that will run on either a standard industrial control or LCNC. This means no . between geometry and offsets values. Others what are using this patch can chime in - I suspect they will have the same opinion. The big difference between Fanuc-style and LinuxCNC style tool changes is not actually in the offsets anyway. That is that the T-word causes the toolchange, not the M6 command. No - the big difference IS the offset application. The fact that you don't have to type M6 G43 is just syntax. The real functionality is the ability to program wear offsets separately from geometry offsets. I've mentioned it before, but the use case is one tool asked to turn two diameters with two different tolerances: dia 1 = 1.000 +0.0, -0.003 - dia 2 = 2.000 +0.003, -0.0.

Being a commercial operation I can move from control to control and the tool data both geometry and wear offsets is handled very similar from control to control (different brands). I think the major differences come into play on the conversational side. Having programmed Cincinnati, Fanuc and Fagor it is my belief that the tool is still described to a pocket or a tool number. I do know that you can call a similar tool from a different pocket in case of tool breakage and or wear. Using Cam for 99.9 percent of our programming the tool is described to the cam system not the machine. In a shop that uses conversational more I can see where the ability to describe tools to the control would be better but I still believe that is driven by pocket numbers. Mazak conversational has the ability to look at the tool description and find that tool but I have never actually used their control.

One line lookahead is a little misleading. The limitation that Steve describes comes from the calculation of the suggested velocity for each line segment.

Re: [Emc-users] Plasma
Viesturs, It depends what kind of machining you'll be doing - the forces in milling are lower than those in drilling. Based on some axis motor testing I did a couple years back, I would guess at a conservative estimate of around 250 lbs per spindle horse power for the worst-case machining parameters. For example, if you have a 2hp spindle and you're using all 2hp, you'll need to deliver 500 lbs of thrust along the axis of cut. Forces required in Z for drilling - Machinery's Handbook (p1061 in Edition 28) estimates 7/8 hole in low carbon steel, 8 thou/rev needs 2313 lb thrust. Also consider that on profiling passes with a high helix end mill you'll see the end mill pull itself into the part - these forces can be higher than milling XY forces as well. How these numbers translate into sizing your rotary spindle stage depends on the geometry of that stage. Kistler makes nice instrumentation for measuring machining forces (http://www.kistler.com/mx_es-mx/4111_Application/Applications-Force-During-Stock-Removal-Process.html). I imagine you could find some academic literature using their instrumentation to give you more exact data.

Re: [Emc-users] Plasma
Viesturs, I was testing in Aluminum, but I think that for a given spindle HP your results would be similar in other materials. If you're on an open loop machine it's preferable to size the motors such that you stall the spindle before stalling an axis motor because it's often an easier failure mode to detect. If you're only using small end mills, then the max axis force required is simply just a bit more than the force required to snap the end mill. I would think that a 6mm end mill wouldn't be capable of delivering 1.5 HP to a workpiece. It's nice (and somewhat surprising) that the website you referenced comes up with nearly the same numbers as my recollection of results from a couple years ago. Formulas like the one listed on that site usually seem to only be good within an order of magnitude.

The starting data I used are: Tool diameter = 6 mm Spindle speed = 5000 RPM (smallest number the Kress 1050 will do) Spindle power = 1,5 hp So max cutting force with given spindle and tool diameter in any material would be 54,5 kg.

Re: [Emc-users] Work Coordinates
Michael is absolutely correct about this: ...so Andy's scheme will report the last offset active, not the current one being used relative to execution In fact, any attempt to display the G5x offset, the spindle S command, or the feedrate F command, the modal G94/95 (feed per unit/feed per rev), G96/G97 (RPM/surface speed) that is current with respect to the motion of the machine will fail because these variables are set during the interpretation of the NGC file. The last values used before a queue-buster (e.g. tool change, probe, M66) are the ones that will be displayed the moment the run button is pressed.

Re: [Emc-users] Work Coordinates
How can I see, what the numbers for the work offsets are and which work offset I am using? For example, I can see the the tool offset values in HAL with motion.tooloffset.x, I would like to display on a Glade side panel - which work offset is being used and what the values are. Is this possible? The work offset being used is displayed in the Active G-Codes field in Axis. That doesn't give you the offset values, but it will at least tell you what G5x offset is currently active.

Re: [Emc-users] GladeVCP / File Selector Button
Andy,
I don't think there's much more you can do to make it neater. If you create
the filter object in your glade file you could get rid of the self.filt =
gtk.FileFilter() and self.fb.add_filter(self.filt) calls, but then you'd need a
builder.get_object('filter') before you'd be able to add your pattern. Glade
doesn't yet allow you to do anything with the filter object:

Re: [Emc-users] GladeVCP / File Selector Button
Andy, You must define a callback associated for the gtk.filechooser's file-set signal. In the call back, use widget.get_filename() to return the file name as a string. As far as the file filter goes, I've not personally used one but it looks like you'd create a gtk.filter object and add the pattern for which you'd like to filter with add_pattern(), then add the filter to the filechooser with add_filter() More info here: http://www.pygtk.org/docs/pygtk/class-gtkfilefilter.html#method-gtkfilefilter--add-pattern http://www.pygtk.org/docs/pygtk/class-gtkfilechooser.html#method-gtkfilechooser--add-filter Rogge I don't seem to be able to figure out how to extract the selected filename as a string into code, or how to set up a file filter. -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

Re: [Emc-users] GladeVCP / File Selector Button
Andy, Those are the docs for a different object, I think. Those docs are for the gtk.Filechooser interface that is implemented by the gtk.FilechooserButton. You can use any of the methods or properties associated with the gtk.Filechooser in the callback. OK, I will try that. I didn't see get_filename as a function/method for the filechooserbutton in the docs. If the file-set signal for your filechooserbutton is named on_filechooserbutton_file_set your callback would be: def on_filechooserbutton_file_set(self, widget): self.gcode_filename = widget.get_filename() print Yippee! From Googling I get the impression that nobody else has ever made this widget work, and that it is in fact entirely useless. I don't know about the filter, but the filechooser button works fine.

Re: [Emc-users] Why do we need G43?
On the mill (HAAS) you use the G43 Hxx for whatever tool you need. Not sure why you need the G43, it seems redudant since I cannot think of another instance where I use H Maybe just tradition. I always thought that this stemmed from shops with extensive tool libraries that do off-line tool measurement. My old HAAS mini mill had a 10 pocket ATC, and required M6 T1 - T10 commands to retrieve the tools from the carousel. If I have 100 tools in my crib (which are measured offline) and I put tool 68 in ATC position 1, I'd want to use an M6 T1 G43 H68 command to apply the correct offset. Pro E's CAM dealt with this sort of thing nicely.

Re: [Emc-users] Trying to understand EMC's operation
All, I have a dual boot computer configured with both Windows/Mach and Linux/EMC2.4.6. I ran Steve's code on both systems and the problem that he describes is evident when running the code on EMC, but not on Mach. To answer Jon's question: Does it start out running well, but then the slowdown develops later in the part program? No - The problem is apparent at the first G2 move. The machine appears to change feedrate between G2 and G1 moves. Moving from one G2 line to another G2 line is smooth, and moving from one G1 line to another G1 line is smooth. G1 moves appear to run at around 60% of the feedrate of the G2 moves, so the transition from G1 to G2 (or G2 to G1) makes the machine seem erratic. If I slow the feedrate down, the problem persists. My test machine is a stepper machine - the change in feedrate is even more noticeable because of the change in pitch at different motor speeds. I don't think that this is a processor power issue, as I can reproduce it even after deleting all but the first 6 lines of motion code (leaving the safety block). Rogge -- Got Input?

Re: [Emc-users] erratic behaviour at low feed rates
If you swap the X and Y drivers it will be fairly easy to determine whether the problem is with the driver (as Gene suspects) or with friction or mechanical linkages (as Jan suspects). If the problem stays on Y after swapping drivers, then your driver is absolved, leaving only mechanical or step signal generation problems as possibilities. You can distinguish between these last two by only swapping the control leads between drivers while leaving the motor leads hooked up as they are now. Rogge If it looses position I would say too little or too much friction in the movement and the steppers jump position.
