Very bad idea (although many places use it). Lets do some ROUGH math.
Assumptions:
1) Assume there is a rule that 15% must fail each class (quite a generous curve, as I've seen 20% must fail in many curves).
2) Assume that if someone fails a class in his/her major, then he/she drops out of the department.
3) Assume there are 10 semesters (about average now), and assume you take at least one class in your major a semester.
4) Assume students drop out at a 10% per year rate for other reasons (an iffy estimate on my part, adjust the numbers if you wish).
1st semester: only 85% of people survive.
2nd semester: only 72% of the starting people can pass. So after 1 year you are forcing a 28% dropout rate - not very good.
1st year is done: 10% drop out since college isn't for them. 65% remain.
3rd semester: 55% remain
4th semester: 47% remain
2nd year is done: 10% drop out as college isn't for them. Only 42% of your students are left.
By last semester only 13% of your starting students are allowed to graduate. It doesn't matter if you started with all straight A, perfect SAT, genious students - you still force 87% to drop out. Would you go to a school that forces 87% to fail? That policy is sickening. By your senior year, the weeds should have already been weeded out. You should be left with a strong core of cabable students. Why still force 15% of your most gifted students to fail each semester just because you have a stupid policy?
