Hi Wong, nice to see you 
I have to say I've never had much luck holding anything with just one clamp (screw)
If it was me I would hold it with two clamps on the perimeter - it should allow you to machine 4 'slots'. Then move the clamps to cut the remaining 4 slots.
When I say move the clamps what I do is clamp the perimeter first with two additional clamps then I remove the other two clamps.
The reason I tend to do it this way is to make sure the part doesn't move whilst removing the clamps.
Bit of a mission but it has worked for me in the past
