how to drill some holes.....

[JG]

Hi Everyone,

 

I have a upcoming job where i will need to drill at least 90,000 + holes in a part (small holes, large part).....the data I will have will be a point with a line going in the direction of the hole C/L, it's likely the point will be mid length of the line, also, I may have a free form surface that the point will lie on. the hole will not necessarily be normal to the surface, they will likely be at some arbitrary angle. any thoughts on how I can go about this, if I have to do it manually I will be ready for the single sleeve white shirt that ties in the back......

 

thanks,

Multiaxis drill with points/lines as your tool axis control....

90000 + small dia holes.......... EDM???

Hi Keith,

 

that was going to be my first attempt.....sometimes it chooses the wrong direction though....

 

thanks again,

How are you coming up with the points and lines?

I use hole axis.... but never had to do more than 60-100 holes...

90k, good luck

three steps:

1.) open mouth

2.) insert large caliber pistol

3.) pull trigger

 

90,000 holes thats crazy stuff right there

are all the holes the same angle, or at least are there large blocks of holes with the same angle?

Hi Keith,

 

the points and lines are customer supplied, thats the way they do it instead of actually putting the holes in a solid body. I'll take a look at hole axis, i've used that before.... Dodgerfan, even if i did that they would still find a way to make me do it....besides, i would not want that job as my last thought....

[SledGeek]

I use this......

Festus,

 

I have not received the file yet, apparently someone is putting the lines and points in, actually i don't know how they put the data in, but i do know (from similar parts) there will be groups of holes that are normal to the surface (no problem there) and groups that have the same angle from a the surface, but the surface is curved making those holes unique as far as programming goes...

The vector must terminate at the point & all the vectors should point toward the spindle, I use a compensation surface for tip control

the hole will not necessarily be normal to the surface, they will likely be at some arbitrary angle.

 

Wouldn't a surface for tip control keep the spindle normal to the surface? (i.e. not what he is after?)

Can you ask the customer how they input the data? If they are using something like an Excel Spreadsheet you can probably export from Excel as a Comma Delimited File that has all of the vectors in it. From there import into MC then select all points.... should work like a charm!

 

HTH!

If you spend 30 seconds on each hole, that's 4.5 months of 40 hour weeks just picking holes. LOL!

Hey Josh T,

 

maybe your on to something there...I'll have to ask how they come up with it in the first place, I'd guess they have a grip routine or something like that....

No, the vectors are controlling the tool/spindle normal, the surface for tool tip control is how I control the depth.

By using a surface for the tool tip control the vector and point can actually be down in the hole.
