Advantages And Disadvantages Of Hacksaw Machine

ABSTRACT

There was always a need of developing some machine which could cut multiple components at a time. A four way hacksaw machine can be used to overcome the problems that arise in the conventional hacksaw machine. This machine can be used for cutting work pieces of varying lengths and work pieces. The main aim of this project is to increase the production rate, reduce the lead time, decrease the material handling and improve the productivity. This project is useful for meeting the mass production requirements in an industry. This project involves the development of a machine which is able to cut four components of the same or maybe different materials simultaneously. Apart from this, the project is provided with a drilling and grinding

Sometimes it does happen that due to the constraint of cutting one component at a time on a conventional hacksaw machine, it becomes difficult to meet the deadline for the mass production requirement. This further results in the overstressed workers and increases the cost of production as they are to be given extra wages for their work. So, there arises a need to develop a machine, which is able to meet the mass production requirements effectively and

For this purpose, he describes the use of a d.c. motor and an eccentric cam mechanism to convert the rotary motion of the motor into the reciprocating motion of the hacksaw blades. He suggests that four components can be cut at the same time of the same or different materials.

In this paper, the focus is on automating the conventional hacksaw machine in order to achieve high productivity of work pieces by using double bladed hacksaw. For this purpose, a d.c. motor is used for the conversion of the rotary into reciprocating motion. Also, there is no need to the measure the length of the workpiece as a mechanism is used to feed the workpiece. This paper also suggests that four components can be cut at the same time.

3. Theoretical Analysis of Multi-Way Power Hacksaw Machine by Ksihsagar Prashant
This paper proposes the machine which can cut four components at the same time with the minimum jerk and vibrations. The project proposes an eccentric cam mechanism to convert the rotary motion into the reciprocating motion. It involves the information about cutting four components at a time of different
