Chorley star Massaro, the world No.1, was in sharp form and put Chinappa under a barrage of pressure that saw Massaro go a game ahead for the loss of just three points.
Chinappa improved in the second and clawed back some points.
But Massaro’s high pace allowed her to retain her comfortable stronghold on the match, with a number of masterful shots cueing a now-trademark fist pump.
And the Lancastrian took the second and third games to claim a hugely impressive 11-3 11-6 11-3 victory.
“I wanted to go out there and make a really fast start and try and be positive from the beginning,” said Massaro, who will take on Omneya Abdel Kawy next.
“I wanted to get in front and I felt like, in the first round, I was a little bit passive to start with.
“It was just about trying to get out and start strong, keep my intensity quite high and I think I probably set a record for the amount of fist pumps considering the length of time that I was on court for.
“I was making sure that I was there for the entire match and that I didn’t let her get up at any point.”
Massaro will be the only English representative in the quarter-final after compatriots Alison Waters and Sarah-Jane Perry both exited the tournament on the third day of action, due to respective losses against Nicol David of Malaysia and Camille Serme of France.
Waters, playing against David in an arena that is named in the eight-time world champion’s honour, went two games down to the world No.5, before marching into a 5-1 lead in the third.
However, David picked up the pace and roared back to take the next 10 points in a sensational ending to 38-minute encounter with an 11-9, 11-3, 11-5 win sending her through to the next stage.
