Getting Thread Variable from Parameter Page

[Mick]

I have an Okuma Post for a 7000 series control lathe, that I've been using since V6. I've modified it to run in all versions from 6 through to V8.1.1. It works really well, and provides the program in exactly the format I want. However, in V9, it doesn't output the correct start position for a G71 threading cycle, as it doesn't read the stock clearance from the "Thread Cut Parameters" tab on the the parameters page. It only outputs the Thread OD instead. I need to get the stock clearance variable from the parameter page, and add it to the thread od value to give me the correct start position. I've tried to find it, but I've had no luck. Can anyone tell me what value I should be using? I thought it was thdxclr, but that doesn't work. Any help would be greatly appreciated.

The post variable THDXCLR is the variable that is loaded with the value input in the Stock Clearance box on the Thread Cut Parameters page.

I entered the value of -> 0.12345

and then 'dumped' the value in THDXCLR in the postblock PG76. The result is -> thdXclr=.12345

The thread OD value in my post is thdx1dia. However, in the threading postblock, if I add thdxclr to it, ie:

 

thdxstart = thdx1dia + thdxclr

n, psg00, *thdxstart, thdzclr, e

 

the value output for thdxstart is the OD of the thread. It appears that it isn't getting the thdxclr value from the parameter page.

 

Please excuse my lack of knowledge on posts, as I'm self taught :/

 

I appreciate your help
