Sitting in a dip machine doing dips is like doing squats in a smith machine. The movement is set to a defined path and your core muscles don't get a chance to work. More so with weighted dips, I find the pecs, abs and lats get way pumped up compared to just strapped in a chair pushing some levers down.
That's a stupid analogy.
and there are so many things wrong with this sentence in general.
All exercises barbell or machine are defined by their paths.
"core muscles" are/should be the deep flatter muscles closer to the spine the the rounder ones you see externally.
the rounded ones do the mechanical work, they have a large range of motion.
the "core" type play a more supportive roll there not really responsible for moving joints but more so just making sure, joints are held together, if they move they fatigue real quick.
using a dip machine will enable one to focus on the limbs doing the movement thus enabling greater inroads into fatigue.
