Accident Avoiding System For Cutting Machine

The aim of our project Accident Avoiding System For Cutting Machine is to take a system-wide approach to preventing the machine accident. The system includes not just the machine and the operator; but rather, it includes everything from the initial design of the machine to the training of everyone that is responsible for any aspect of it, to the documentation of all changes, to regular safety audits and a finally a corporate culture of safety-first.
Design is the part of a machine’s life where the greatest impact can be made in relation to avoiding accidents. The designer should ensure that the machine is safe to set up and operate, safe to install, safe to maintain, safe to repair, and safe to decommission.
Although safe operation is usually at the forefront of a designer’s mind, safe maintenance and repair should also be a high priority. Around 50% of fatal accidents involving industrial equipment are associated with maintenance activities, and design is a contributory factor in some 32% of these fatalities.
In our project the IR sensors are used to avoiding the accident. The system automatically stops, when the IR sensor detecting the any parts of the operating inside the machine.
The designer should make the machine as reliable as reasonably possible to minimize the maintenance requirement and allow for long intervals between routine maintenance tasks. It is also important to design the machine and its control system so that maintenance can be carried out safely.
For example, hold-to-run controls can be installed that allow a machine to be run at a reduced speed, or removable tool holders can be used so that sharp blades can be replaced on a workbench instead of in a difficult position inside a machine. In addition, operators and maintenance technicians must be discouraged from bypassing safety equipment.
Safety components are often designed to interrupt processes in the event of a fault and will have an impact on machine availability. In order to minimize this effect – and the temptation to interfere with the safety circuits – high-reliability, safety components should be specified so as to keep the number of nuisance faults at a minimum.
Designing safety into a new machine is important, but it has to be remembered that the vast majority of machines do not remain unaltered, with unchanged operating procedures, for their entire lifetime.

Modifications are almost inevitable and working practices can evolve or be deliberately revised by managers in an attempt to improve throughput. Any changes made to the machine or the way it is operated also changes the original risk assessment. Research has shown that a significant number of industrial accidents result from uncontrolled changes. It is usually via a complex sequence of events that a change leads to an accident.
Clearly, it is necessary to ensure that machinery and operating procedures are fully documented. Even if a machine and its associated safety systems are all properly designed and documented, it is vital that the machine is monitored during installation, commissioning and first-off production. Often it is necessary to make small changes during any or all of these stages.
It is imperative that any proposed change is first subjected to a rigorous risk assessment, and any changes that are implemented must be fully documented. After production has commenced, a further review should take place to make certain that no further changes have been made. Note also that “no further changes” also refers to the raw materials or components that are being processed by the machine. Audits should be undertaken on a regular basis to check that the machine and operating procedures are still in the documented state.
Furthermore, functional audits should also be carried out on the machinery safety systems. Often the components in a safety control system are only used in the event of an emergency, which can make them very difficult to test. Nonetheless, these systems should be tested at regularly scheduled intervals.
Safety field buses such as AS-I Safety At Work (AsiSafe) and Profisafe can support intelligent field devices able to perform self-monitoring functions and transmit diagnostic data to a central controller that can alert the machine operator prior to the failure becoming an unacceptable risk.
Education and training is another aspect of the company-wide approach to machinery safety. Increasingly complex modern machinery makes education and training ever more important. There are new standards and regulations with which companies must comply. On-the-job experience may have sufficed in the past, but this is unlikely to be acceptable in the future.
Obviously training for machine operators and maintenance technicians is a requirement, but there is also an important need for more general education of the workforce and management in order to generate a safety-first corporate culture.
