incremental repeat function?

[Joe Miranda]

I have a milltronics lathe with a cent 5 controller. Say I want to bore a 1.000 dia. hole and I have a .750 dia. starting dia. Is there a repeat function so that I can say something like repeat this boring move 4 more times moving
.0625 inc in the "x"? It seems like there should be a function similar to the mirror function of the scale function.

Thanks,

Joe

I ended up using the face grooving function under the drilling heading to bore my hole. Is there a better way?

use the turning rough event.
just make sure your start position is set below .750.
hope this helps

Lyn,

OK - I will try that. Let's see ... how do I get it to move out incrementally rather than in? I'm not looking at my control right now and maybe it's self explanatory but I thought that there was no sign involved in the incremental move. I must be thinking wrong about that. Do I just reverse the sign - in other words - if when you are turning you tell it to move in the minus direction when you ar boring you tell it to move in the plus direction?

if your start position is set smaller than your final dia.,it will increment in the plus direction. if your start position is set larger than your final dia., it will increment in the minus direction.

Ah! Thanks. I am learning so much from you guys. Thanks.

Joe, load the attached files into your machine and take a look at the ID turning program. This may give you some more help. I had to insert a txt file extension to the file name so that I could post the files. Just rename the files to O2006 and P2006 and then load them into your machine.

I just came inside after another frustrating evening in the shop. I thought I understood what Lyn was saying and I wrote a program with two boring cycles and could not get them to work. At the end of the "z" minus move it would make a move in the "x" plus direction!!! What the heck?! I thought when your start move is less than your final move it increments in the plus direction and vice versa. What's with the little "x" plus move at the end of the "z". That's catastrophic. It must be the way I defined the "U" and the "I"? I see in the one text file that you sent me that you have them defined with negative signs. I didn't get your post until I came in and I'm going to bed and I won't be able to get back at this until Wednesday. If you will let me know what you think it would be helpful.
Thanks.

If it moves in the x plus direction at the end of the z minus move, the control is executing a od turning cycle. Try moving your x start further in towards the center of the chuck. Keep trying, it will work. Hope this helps.

Lyn,

OK. I will try that either later this evening or tomorrow. I am busy with my other job today and I have a class tonight plus my refrigerator conked out and I am going to pick up another one this evening (hopefully). Thanks for the help.

are you programming in conversational of text? and do you have a programming manual?
call milltronics and get one if it did not come with your machine. it has several examples of different parts and explaines how to answer the conversational questions and why.
when it clicks with you, it will be the easiest control you have ever programmed. think how you would do it on a manual lathe with DRO and then program the cnc like wise
good luck

Lyn,

I tired what you said - no luck. I then went through every parameter in the rough turning sequence and tried inserting a different value and I finally figured it out. But it's been a couple of days and now I have forgotten what I did. I will have to go and stand in front of the control for a while and try to remember. I will try to post what I did so you can see where I made my mistake. Maybe you can shed more light on what I am doing in terms of my approack to pragraming the workpiece.
Thanks.
