I need to make a plate that will blank off a hole left after modifying a machine at work.
The attached PDF shows my attempts so far, it's a simple 12mm (1/2") thick plate & only the holes internal to the outer profile need to be accurate to any degree.
I've tried to draw a smooth & flowing profile around these holes that will machine with a 16mm cutter but it just doesn't 'look' right, both in the drawing & in the prototype.
I'm so much of a beginner at design that I don't even have the words to describe what I'm trying to achieve, can anyone see what I mean & point me in the right direction?
