Polygons for radius bends

Hello,

  I am a new to the forum and modeling so please bare with me.I like to create polygons for big radius bends so they can be bumped on the pressbrake.The polygons create individual bend lines that can be unfolded  in flat pattern .My question:is there a way to make more than a 40 sided polygon.Why is that the limit?
