    nose radius/P numbers

    I only program in IGF mode. I have the OSP 5020L control. On the tool data page, are the x and z nose r comp numbers simply the radius on the insert? Do I enter the insert radius on both the x and z? Or am I mistaken? Also, do I have to enter a P number? What is the P number?I have been reading manuals for hours and I am still not certain. Any help would be greatly appreciated.

    yup

    Do I enter the insert radius on both the x and z?
    yeeess; i really have no clue why there are 2 fields for that

    Or am I mistaken?
    no, you are always right

    Also, do I have to enter a P number?
    if you wish + it may help

    What is the P number?
    try 3

    I have been reading manuals for hours and I am still not certain.

    Well, the boring op is cutting .06" under. But if I change nose comp to zero, it bores to the correct size.

    Re: nose radius/P numbers

    I figured it out. The P value was the problem. The P value determines which quadrant the nose comp is figured from. But I am very grateful for your response. Your recent advice has been helpful.

    P tell machine where is tool radius point. Click here for picture and better picture click Here

    So depend on how your machine setup relative you the part, that is how you put in the P.
    The best way to learn is trial error.

    Re: nose radius/P numbers

    Kitty's guide is correct for P values. As you can see some have only X and some only Z values for radius comp, thus two registers, but only one is used. If you use the P values, it will automatically correct for data entry error such as sign +, - direction entered wrong. Also you can only enter 1 value and it will take the larger number and use it for comping correctly when the P is used. 3 is normal OD and 2 is normal ID turning. If no P value is used, then sign and value matter for the comp registers.

    Best regards,
    Experience is what you get just after you needed it.
