Chamfering the 90 degree corners of a board is a good idea for a number of reasons.
One of the most obvious is to protect workers from hand injuries.
Often it makes the assembly simpler to assemble... and sometimes they are used as a 'lead in' to a housing that requires sliding the board into slots to assemble.
Most common is 50 mils by 50 mils, a 45 degree chamfer.

Subject: [DC] Chamfered PCB
I've got a request if a PCB can be chamfered. My initial inclination is yes, but I've never been asked.
What makes this difficult is the small size and one side in rounded.
PCB is 35.95mm long X 12.10mm wide (standard 1.57mm [0.062in] thick)
Chamfer would be 45 or 55 degrees all the way around, except the one width (12.1mm) side would be straight.
Shape is pcb is like this:
