Re: Cranks and buttons
Darrell
I don't know about the other manual mills, but retro fitting a Bridgeport

manual mill is not a cost effective plan. A good Bpt manual goes for around $7000 add ball screws, motor mounts, motors, power supplies, driver cards and a PC control and you have just spent $6000 to $8000 on the retro fit and now your "new" machine is worth about $5000 - $6000. If you have room, just get a BOSS control machine and add a new control all for less than $5000. If you don't have room for both, sell the manual and take a vacation with the $2000 profit.

Re: Jog Pendant
the only machine I've seen that used a joystick to jog is the Omniturn
retrofit package and that just used a digital stick in place of the usual 4 jog buttons it seems like a good idea at first but the stick turns out to be awkward to use for jogging ,buttons and an encoder dial are much more natural (for me ) a better use for the j-stick port might be to use the joystick button inputs for jogging and wire the analog inputs to feed/speed override dials(in 10% increments) that is IF you wanted to use the j-stick port at all ,you wont be editing in another window while jogging so the normal keyboard commands should be ok my concern was Jon's point about E-stop being the only way to bail out in the situation he described on most of the machines I've worked on the 3 main pendant controls are E-stop,feed hold and cycle start ,and are always grouped together in the easiest to reach spot on the pendant jog controls and override dials come next and the keypad and edit functions usualy get pushed to the top-far side of the control Brian The problem with the PC game joysticks is they are extremelydiscussion of shop built systems, for CAD, CAM, EDM, and DRO.

From: Fred Smith <imserv@...> html/search-bool.html&r=17&f=G&l=50&co1=AND&d=pall&s1=Hurco&OS=Hurco&RS=Hurc oI read this post and the patent it references right before I went to sleep. I just now awoke in a cold sweat after having the strangest dream: My wife and kids were trying to keep the cops busy at the front door. I was in the bathroom desperately trying to flush a huge K&T CNC mill down the toilet. I kept pushing on it, but it just wouldn't go and I could hear the cops coming down the hall... Matt |

I can't allow a machine that can exert over 1000 Lbs of linear force to be controlled by something that unreliable. Jon |

Again, I sure wish I could get you in front of an AcuRite machine.Yup, I had the local dealer for AccuRite out to show me their system. The CPNC was VERY impressive, I was very excited, until I heard their price. At the time, they only had what they called 2 1/2D, that means 2 axes with motors and one with a linear scale and manual movement. All that for ONLY $13,000. And, I think, ballscrews might have been EXTRA! I tried not to laugh as I ushered the guy out. I'm doing without, and not too unhappy. If somebody comes out with an affordable way to add this feature, with or without graphics, I'll gladly add it, but I'm not going to pay $13,000 for it. Jon |

I sometimes machine with the jog keys, but that ties up one hand, so I often key in the G-code to make various cuts. I can key in a multiple command, and mill down an edge, pull away, and then quickly return to the begin point, all with one key press. That way, the tool doesn't dwell at the end waiting for me to enter the next command. Jon |

Jim,

I have Vector CAD/CAM and am a very happy customer. It is easy to use, amazing in what it can do (just love the pocket and skin functions), and best of all the support from Fred at IMService is the best. If I had to come up with a complaint it is that the program will not let you use long file names. I am just a home shop hacker, but sure do feel I would not want to do CNC without Vector. I have no relationship to Vector except as a satisfied customer. Tim [Denver, CO] -----Original Message----- |

But, after using Vector for a while, I can get around in it very well. In fact, I use it more than Autocad 2000. Vector has contour milling, pocket milling, true type font machining, copy/cut/paste, dxf input, etc... Fred Smith has been very good to work with. He is one of the reasons that I continue to upgrade. Lately, I have been calling him and bugging him about buying the next release that has surface machining. Thanks, Dan |

I'm just getting started with it. Been limping on a demo 14.0 version of Bobcad for several years (cutting and pasting 11 lines at a time into Notepad...). Vector is different from Bobcad, and there appears to be as much or more CAD oriented features as CAM. That does me little good as I'm ususally working from geometry created from Cadkey files. I'm sure the CAD features will come in handy sooner or later when I catch some booboo while programming. If I stay with Cadkey another revision, I'll move on to Acucarve eventually which runs from inside Cadkey. But for now, it appears to be a great tool at a good price. And, I doubt you will find better service/support than offered by Fred Smith, here on the list. Jon |

Re: Subject: Manual Vs CNC Was Re: Names
Jon Anderson
Sometimes CNC can be the way to go for even a single hole.
Some years back in a sheetmetal shop I worked at, a custome rectangle punch/die was ordered for a job. Needless to say, it showed up at the very last minute, and the operator quickly discovered the index pin was missing, along with the hole! The supervisor brought to me and asked if there was any way in heck I could put a 1/4" dowel pin in the hardened die. I hand ground a solid carbide spade drill, programmed a single through hole with peck increments of .001. Gave it lots of coolant and walked away. 15 minutes later, we had a perfect thru hole. I'd not have wanted to stand there pecking a manual machine like that! Jon |
