Lord parashurama came to fight with lord Rama when lord Rama broke the hara dhanu. Now, why these two avatars meet with each other? What was the main motivation of this occurrence? Does it mean that lord parashurama wanted to say/give something (his bow to defeat Ravana) to lord Rama?
While returning back to Ayodhya marrying Sita, Lord Rama encountered Parashurama.
In that catastrophic darkness, that sand-muffled military of king Dasharatha has seen the son of Sage Jamadagni, namely Bhaargava Rama, the subjugator of kings of kings. He appeared calamitous in his look by wearing tufty matted and unruly head-hair, an unassailable one like Mt. Kailash, an unbearable one like the Epoch-End-Fire, irradiant with his own radiance, hence imperceivable for commoners, and such as he is, he clinched an axe on his right shoulder and clasped a bow in his left hand, that in simile is like a congeries of electroluminescence, and handling an arrow which is as if ready to electrocute, and he vied in his overall look with the devastator of triple cities, namely God Shiva.

- Parashurama challenged Lord Rama -
Take an aim with an arrow that conquers enemy's citadels fixing it on this supramundane longbow... and oh, Kakutstha, should you be capable of it, thereafter I will give you a duel... [1-75-27]
- Lord Rama accepted the challenge -
Raghava, the nimble-handed vanquisher of his opponents, speaking thus in high dudgeon expropriated that estimable weapon, namely the longbow of Vishnu, from the hand of Bhaargava Rama, along with the long-arrow that is already fitted on it... [1-76-4]
- Lord Rama successfully wielded the bow of Vishnu -
On lifting up the bow that is already fitted with an arrow on bowstring, then Rama started to take aim with it, but being indecisive about the target, then Rama of Dasharatha irefully said this to Rama of Jamagadni. [1-76-5]
- Parashurama recognise that Lord Rama is Vishnu -
"I have realized your touch of nature as that of the Immutable Supreme Being, God of Gods, the Exterminator of the demon Madhu, namely Vishnu, by the touch of your handling that bow... oh, enemy-inflamer, blessedness alone betides you... [1-76-17]
- Lord Rama destroyed the ascetic merits of Parashurama -
But I triumphed over matchless realms of heavens with my ascesis, oh, Rama, you may hash them up with that irreversible arrow... let there be no time-lag... [1-76-16)
- Parashurama leaves for Mahendra mountain -
On seeing all of his realms of heavens are shot-blasted by Rama of Dasharatha, Rama of Jamadagni vanished in a trice to Mt. Mahendra, the heavenly mountain. [1-76-22]
