work holding

Hi all,

I am aware this is not directly related to topics of this forum, however I would imagine there are many members who are experienced in manufacturing alongside their CAD.

I am looking to machine the component shown in the below image, using the most efficient work holding method.

I have thought to maybe use a vice for the central features and then bolt the part down to the bench using the holes to machine around the outer profile.

or

to grip the initial material in a vice, machine the central features and then machine around the outer profile leaving 1mm at the bottom as not to completely seperate the component, then peel it out later,

Thanks all
