I might be able to help. I need some more information.
Are you using a conventional die, punch and blankholder?
What kind of material are you trying to form?
What shape is the blank(square/circle)?
What size is the blank?
What is the material clearance in the die?
What is the size of radius on the draw die?
Are there wrinkles in the failed parts?
What is the surface finish on the blankholder and die?
What type of lubrication are you using?
What type of press are you using(single/double action)(hydraulic/mechanical)?
Are you attempting this form with multiple draws or just one?
How close to the bottom of the draw can you get? Does the punch go thru at first contact of the blank or does the bottom rip out half way down or near bottom?
If you can post a picture of the failed part I may be able to see some problems.
