1st i would do the left holes first, then move to the right to eliminate travel.
so
x15y35
y-35
x100
y35
then start from the hole you ended on and do the same for the drill.
2nd ,i assume that the endmill isnt coming down into the part, would be to feed faster or even rapid to the desired z depth.you can also rapid out of the part.
getting rid of the n lines for every line will help a little.
that's all for me for now, metric hurts my head.
