Mori NH-5000 tool life management question

[Slixmix]

We have used too life management on our insert cutters to let us know over a certain time to replace inserts. Now I want to implement setting up multiples  of the same cutters. On our 60 tool magazines the program calls up H99 for each of the cutters and it reads the tool length from the register for whatever tool it is. My question is on this machine there are 180 tools. Is it still H99 in my program or is it maybe H9999? How would that affect the length if I actually had a Tool 99 in the machine? TIA.

My guess is that the G43 actually calls a macro prg.

 

The macro would do something like

IF #8 EQ 99 

Do some stuff with the current tool number variable

G00 G43 H#(set to the value of the current tool) Z#26

M99

 

So having a number other than 99 uses that number and using the length offset of 99 will use the current tool; if the current tool is 99 it uses 99.

 

Just a guess, look in your 9000 programs.

Our NH5000 has 120 tools here and with TLM we are still using G43 H99

Makino has a tool data transfer(M56) during the tool change(M06). Might be something similar.

You want to use H99/D99 in your program for any tool using TLM. The control doesn't allow you use H99/D99 in the program unless it's a TLM tool. Typically we avoid using tool 99 in the magazine for this reason. We have 1 horizontal with all 120 pockets filled and tool 99 uses H199 however when trying to use this scheme in day to day setups usingT99/H199/D199 mistakes have been made and even had a crash as a result, so the preventive action was not to use T99.

 

The T number you call directs the control to look in the TLM table to figure out which tool is active. In the TLM table the H & D is assigned to the T number. Once the tool life is up, either from time in cut or number of pieces, the control flags that tool as expired and next time that tool is called the control will pick up the next tool in the table list.

 

BTW, when using TLM in conjunction with load monitoring you can set a threshold for an Operator Message at a certain load percentage that will flag the tool. Also there's another threshold that would put the machine into alarm state.

Thanks! We'll give it a go.

I must be missing something. I went to prove this out and it's not reading the G43H99Z.10 It grabbed the correct tool just not reading the height offset for the tool (The last tool that ran, height offset is still active). I've attached a pic of the TLM page. Was just reading the book and it says the H99 can be changed (probably to not mess with T99 in the machine). We bought this machine used. Maybe that's the case  Here's my code:

Hmm. After I read the attached pic I changed the T1001 to be right before the M06. Now instead of the using the last tools height offset it changed to H99 which is zero in the control because there's no tool there yet. I'm thinking the parameter was changed to a different number. Now how do I get to parameters 13265 and 13266?????

 

Edit........... I found the parameters. They've been changed to H200 and D200.....

You're Welcome!

Enjoy the new machine!
