in my simulator your tool movement looks strange but nothing like you describe.
your tool moves away from the chuck. is this external or internal tool?
where is your Z0? it should be set on the face and the Z's should be minus but all of your Z's are positive.
did you generate the program with software or by hand?
what are you actually trying to machine..... give your part dimensions etc or a simple sketch and I can give you some working code.
