The broaching operation in which the work moves past the stationary tool is called: 

The broaching operation in which the work moves past the stationary tool is called:  Correct Answer Continuous broaching

Explanation:

The differences between push, pull, surface and continuous broaching are as follows:

Pull Broaching
  • Work-piece is clamped to the broaching machine in a stationary position and the broach is pulled through the work.
  • Broaches are usually long and are held in a special head.
  • Mostly used for internal broaching.

Push Broaching
  • Work-piece is held in the broaching machine in a stationary position and the broach is pushed through the portion of the work-piece to be machined.
  • Normally it is done by hand and arbor presses (hydraulic press).
  • It is also recommended for internal broaching like sizing and finishing hole cavities and keyways.

Surface Broaching
  • Anyone of two, either work-piece or broach (tool) is kept moving and the other is kept stationary.
  • Broaching tool is specially designed for the shape to be finished.

Continuous Broaching
  • In continuous broaching, the broach is held stationary in the broaching machine and the work-piece is moved continuously.
  • The teeth movement of the work-piece may be either straight, horizontal or circular.
  • Generally used for broaching a large number of similar work-piece at a time.

Paddy transplantation in Punjab is a very hard labor-intensive back-breaking job. In the transplant season, teams of special people swarm the entire rural landscape employed by the farmers and can be seen laboring away in the fields under the hot sweltering sun. Farmer Jagtar Singh has a full-time help at his sprawling farm who goes by the name of Hari, and who hails from Allahabad, UP. During the paddy transplant season, it is up to Hari to rope in his brothers, sons, and cousins from his native village to complete the task well in time. All his people are skillful and masters of the trade and equally efficient at their jobs. So, this past season, this is how the work went. Hari started the work and after 't' hours was joined in by his brother Jaggi. After another 't' hours, Neelu, their cousin, also jumped into the fray. So, after every 't' hours, 1 person kept on joining the team of already working men, and this process kept on continuing till the completion of the work. The last person worked for 't' hours. In the last season, the very same men had completed the same work working 2 shifts of 12 hours all of them working simultaneously owing to some peculiar weather conditions and time constraints. Jagtar Singh is a fair and just paymaster which is why he faces no labor shortage at this crucial time and which is why the whole 'Hari clan' are more than happy to work for him and are at his beck and call. He pays each of them individually proportional to the work done by them. This time around, Hari received 11 times as much as Surinder, his eldest son, who was the last person to join in. In how much time was the work completed?
