CROSS-REFERENCE TO RELATED APPLICATIONS AND PRIORITY
[001] The present application claims priority from Indian Patent application no. (201821041291) filed on 31st October, 2018.

TECHNICAL FIELD
[002] The present disclosure in general relates to the field of manufacturing. More particularly, the present subject matter relates to milling cut collector for outside machining of web of submarine.

BACKGROUND
[003] Generally, circumferential machining of frames and web elements generates a lot of metal scraps that get scattered on a machine floor and nearby area. The scattering of the metal scraps may lead to injury, accidents or hot burn on the hands of operators during jamming of a jack. As a huge amount of metal scraps scatters on the floor the operators face a hurdle in their movement around the machine or may pierce into the shoes of the operators and thereby damage the shoes. However, cleaning and dispose of the scattered metal scraps involves additional labour cost. Also, the metal scraps resulted from the circumferential machining are quite hot and occasionally strikes the nearby operators or passer-by causing injury and damage to their boiler suit. Sometimes the metal scraps fall on the pathway of the jacks of machine resulting in jamming. Milling mechanics are required for repairing the jammed jacks and hence it adds to the labour cost. During the time of cleaning and repair of the jack, the machine is kept idle which leads to production loss. Hence, the working environment gets unsafe since no mechanism exists for collecting and removing the metal scraps from the working machine area.
[004] Conventional system and method generally relates to manual collection and disposal. Some of the conventional system and method includes a complicated method to remove the metal scraps. Removing metal scraps by vacuum method involves creating a vacuum and transporting the metal scraps through large pipelines and dumping the metal scraps at the point of discharge away from the machine. Some other conventional procedures include a positive pressure method, where the pressurized air is passed through the cutting area and metal scraps are blown away by pressurized air and metal scraps are collected and transported through pipes to the discharge area.
