Hi deco doc,

I have PMd you my another email ID
Please check it.

Hi deco doc

Is there any limit for threading length in ENC 162?. And can we use two tools at a time, one for rough cut and another for finish?. Actually, bar stock is 14.2mm and i want to use two tools at a time, instead of giving whole load on single tool.

My another problem is, when I set geometry offset in W place for T6, i have to also adjust for other tools and this is messing up the dimensions of part. And i m not able to adjust the distance of part in the mid of tolerance and total lenght also is not coming to that value what i have mentioned in program. Overall We are not getting the distance on part what we have programmed. If you have solution for it please reply me.

Thanks

Hi Chetan

You did not say what length of thread you want to make, I assume you mean to screwcut? Normally for screwcutting you dont want to exceed the internal land length of the guide bush, otherwise when the threading tool cuts the bar diameter with a full form insert there will no longer be any support at the bar diameter from the guide bush. You can set the tool further away from the guide bush to increase the length a little, I use a left handed tool for this.

You can use two tools to cut at once, but only for turning, not threading.

Hi
Exactly i mean screwcut only. Part is having 25mm threading length.M8x 1mm(Right hand). Bar stock is 13mm. How it can be done? Do i need to first turn the bar upto 8mm and then screwcutting.? If yes how guide bush will support the bar then. Can we use threading canned cycle.?

Hi, Martin this may be too much to ask but i have been setting/programing a deco lathe and would like to know if you have any c axis programing examples, as i would like to know about programing this axis, never had to use it so far but would like to know how to for the future.

Cheers.

hi
you can read in tb-deco software's help menu, the code is m198.

Hey Martin,
I have an ENC264 and was wondering if there is any way to use my geometry/wear offsets without setting them with a g10? everytime I need to change my part size I have to manually edit my g10. Can I use my g10 for geometry and still use my wear offsets to control part size? Or am I just stuck using g10? Any help would be appreciated. BTW I Don't have a presetter.
thanks
Dan

Hi Dan

The ENC264 is an old machine that I don't know at all, but I will try to help you.

As I understand it you could just alter the wear offset to adjust the size of the part, you could also delete or bracket the G10 comand in the program and then use the geometry offset to adjust the size of the part. I don't think you need to use the G10 to enter the tool geometry as you should be able to enter the tool geometry directly from the control. This procedure is described in Chapter 5.8 of the Manipulation manual.

It is normal practice to adjust the geometry to get the part size correct while you are setting with a new tool, and then use the wear offset to adjust the size of the part while in production.

Hope this helps

Hi Martin,

What is the use of M90 and M91 command in ENC 162. Actually i have one query that in programm manual they have given sample in which there is no M10 and also no command for returning haedstock. Why is it so?

Hi

Looking at the programming manual the M90 command is 'Reduce speed, fine precise stop'

The M91 command is 'Deviation command, block transition with no drop in speed'

M90 is the default modal command, it means the cutting tool will reduce its velocity at the end of the current block (segment) to make sure the tool makes a momentary exact stop at the end of the block before continuing with the next block. This is to ensure that the programmed cutting tool path is exactly followed.

The M91 command supresses the exact stop of the cutting tool between blocks allowing the cutting tool to make a continuous movement between each programmed block.

The M91 command is used where a cosmetic surface finish is required when an exact stop between segments leaves a visible mark on the surface of the component, for example where there are several intersecting radii along the outside of a part.

When using the M91 to supress the exact stop between segments the tool may deviate very slightly from the programmed tool path.

Hope this helps

Hi Martin,

Thanks for the help. I m asking you too much about this machine. this is my first cnc m/c. Can you tell me how to use sub routine G160 H9918 (Manual Pg 34)?

My m/c gets stop at G160 H9810. Doest it mean that my m/c has lost this sub routine? If yes then how to get it.
