    Sorry to break your balls a little, but unless you are using V9. Mastercam and Turning is asking for a headache. Been there, all the conversations about how slow and wrong stuff is and how to make it better, all the while ignoring the fact the Mastersuk is not Turning software anymore. Don't get me wrong I use MCam more than any other software, for Milling it's great, but since X, meh...for Turning. It barely passes itself off, luckily we still have V9 on one of the computers.

    I think this post deserves a "well, that escalated quickly" image, but I'm too laszy to attach it, so here's a link.

    some guys are hot tempered, and this may put them in a bad situation

    is important to have patience and be able to locate the issues, especially with teenagers

    well, this does not mean that that guy, leaving, did not make you a favor

    i met guys really stressed from previous working places, acting unsafe, etc, and some of them turned out well

    in the end, is a lotery

    but with all respect, that question of yours is pretty basic for 22years (=15 years killing my body and 7 years killing my mind)
    ...maybe this is why your rookie left

    ps : this will get me in flames, i know

    Every shop has standards.
    The new guy, no matter how experienced, has to adopt to your shops way and one should be able to explain how they all come out the same.

    My dot is the one in center on the bottom of tip. The one on the left bottom also has some advantages.
    Namely that entering any offset or calculating is time consuming and gives you one more number to fat finger screw up.

    The kid may have a point but you can't turn the shop rules upside down just because the newbies never punched a tape.
    But those who did need to understand the new kid's methods also and not just shoot them down thinking my old methods are the "right" ones.
    Do so and yup, they will quit, at which point you are now short a man. Now everyone does the lose-lose thing which is not productive.

    Hello Tom,
    So where is the setting datum for full radius tool being set on the machines with probes (Tool Setter)? It can't be easily set for centre radius for that type of tool and then to the leading edge in X and Z for a R/H OD turning tool, unless you have an underlying Macro driving the system where a Tool Type can be passed as an argument.

    Regards,

    Bill

    One advantage with tip no. 3 in external machining is that at least in straight turning and facing, there would be no error even without radius compensation (ignoring end effect).

    I wont flame anyone! I posted the question to prove to him that the world doesn't rely on how they were trained and to show him that there are multiple ways to wind up at the same point. I was trying to help him become a successful machinist but his age and lack of respect for knowledge led to his demise. I have worked in some real hell holes for some real bastards and I pride myself on not EVER making someone feel the way some of my past supervisors have made me feel about simple mistakes.

    I usually program them correctly. however this instance I had to use a center point style for the bottom of the V-groove we are cutting. We were having blending issues with the 'correct way' and it blended beautifully this other way.

    I am writing the policy, procedures, and standards manual

    I never shot him down or belittled him, he continued to escalate the issue until he quit and when he quit he did it with style, I can give him that.

    I teach everybody differently, I usually adjust my teaching style to the trainees learning style. Bottom line is he was a bottom of the barrel student (I contacted his course teachers to find out where to send his check and they gave me the low down.)

    this part does not run on those machines. we have a "cell" style of grouping our machines here

    Balls busted?? let me check........ nope I am still intact.... we are slowly excommunicating our 2 axis lathes and replacing them with machining centers. we have 3 mill/turn machines (live tooling and live y axis)

    You are not experienced enough in this subject.

    Deadly kitten clogs up more threads with useless, complex, difficult to understand replies.
    At best, his solutions are bizarre, some are flat out retarded.
    He gets corrected quite often by more knowledgeable members to try to keep the integrity of the info on this board.

    While you are tooling them up get Esprit, trying to make Mastercam® work for Mill/Turn machines is a nightmare. The worst thing is that CNC software® and Mastercam® Engineers will lie to your face before the Maintenance bill arrives, about how well they handle it, and how easy it is to modify the post. Don't listen, Mastercam is not designed for it.

    They will try to modify an existing post to fit your needs, BECAUSE they haven't written an original for it. That is like the car salesman that promises to fix the used car just like new. Sorry MC rant over.

    No, that's not the case at all. I'm non racist and a strong believer in equal opportunity. Accordingly, I regard ALL pretenders with equal contempt.

    This Num Nut is a pretender of the most profound order. In another recent Thread, where there are over 100 Posts (a Thread that should have been concluded is half a dozen Posts at most), the majority of the Posts are from the Pussy, basically arguing Black is White, and me and others batting the ball back, trying to convince him that there is actually a difference. His greatest fail to date and it happened in the aforementioned Thread, was that he advocated using the one tool (one insert) to both turn a shoulder feature and screw cut to the shoulder. Even the greenest new chum knows better than that. Sounds like the Go To person for advice - NOT.

    So you usually set the Full Radius Tool to the edge, but for that job you changed to Radius Centre setting. So why did the new guy's method seem so out of kilter?

    I can't see how changing the way the tool is set would make a scrap of difference (apart from one program being harder to read if TRC at the machine is not used). To the control, the program path is just a series of numbers, the resolution of which can only be as fine as the Least Programmable Increment of the control, irrespective of where on the Insert the tool is set.

    Regards,

    Bill

    nice one Tom you are not a parasite ...

    in this moment i have codes that use 2 different reference systems on same insert

    thus programing_point <> tool_senzor_point

    code is created with translation factors, that simply compensate the geometrical difference between those 2 points

    a soubroutine checks input corections, so cnc will stop if an offset is out of tolerance

    admisible tolerance is <<< geometrical difference



    this was an example for using translation factors

    translation factors + rotations, scale, mirror, etc, are geometrical functions

    such functions can be used by :
    ... implementing them into code
    ... switching cnc status :
    ...... from code
    ...... from control switches

    for me it began when the control could not handle negative radius when milling on spindle frontal



    you said that you have 3 live axis lathe

    if you wanna drill a hole with 2 drills :
    ... on a mill, both tools will be in main spindle
    ... on a lathe, each tool will be in a live holder, and live holders do not index with their axis colinear; thus, the 2nd drill will be a little excentric

    if you put inside each live tool a center drill and drill at same coordinate, than you will get a different point for each tool

    this deviations exist, but generally are lower than the part tolerances

    however, as a result, life spam for mill tools working inside a lathe may be reduced, compared to tools working in a mill

    if at some point you will need to deliver tight tolerances on a random part on a lathe ( by milling with live tools ), you may find transition factors to come in handy

    kindly !

    i also have in mind future aplications for using multiple_points on same insert, like making life easier for less experience operators, but so far is only an idea

    the reason for it is that sometimes i hear : i input an corection and the machine did not take it, and in that moment my tension raises, because a specific setup may fail from such a mistake, and is me the one who will have to put it back
