Morning schedule turned round at place one has cut off (9)

'one has cut off' is the definition.
I can't judge whether this defines the answer.

'morning schedule turned round at place' is the wordplay.
'morning' becomes 'am' (as in ro:00 AM).
'schedule' becomes 'rota' (I've seen this before).
'turned round' shows that the letters should be reversed in order.
'at' says to put letters next to each other (I've seen this in other clues).
'place' becomes 'put' (synonyms).
'rota' written backwards gives 'ator'.
'ator' after 'put' is 'putator'.
'am'+'putator'='AMPUTATOR'
