Abstract
Preventive maintenance is early access or pre-planned maintenance of the problems occur in any machinery units and it has become the important part of today’s industry to avoid breakdown as it can save costly faults, keep Continues production with standardize machinery, reduce waste and also important for safety of deployment. The paper describes the way to avoid breakdown in CNC’s by using time based scheduled preventive maintenance for different parameters, while taking 20 CNC machines under observation. PM sheet of CNC’s is divided into parts over time for different parameters like chuck pressure inspection is kept in daily basis list while ATC Arm in 4 month check list. Some parameters set on the basis of theoretical studies of material fatigue life and some on experimental basis in the resultant sheet. The developed sheet could help manufacturers to figure out the problems in CNC’s on their usage over time range, simply the sheet can be taken as survey of performance of CNC’s. Also a proper planed PM sheet can save a valuable amount of money on maintenance.
Highlights
Maintenance is a most important activity in production process since it accounts about 60 to 75% of its total costs; including material, transport and technical support costs
To maintain the standard of product, performance of equipment can only be preserved by its preventive maintenance [3]
The research is focused on problems arising in CNC machines after scheduled preventive maintenance for different parts of CNC’s
Summary
Maintenance is a most important activity in production process since it accounts about 60 to 75% of its total costs; including material, transport and technical support costs. A proper scheduled preventive maintenance modal can be solution for increasing components life, decreasing cost factor sudden breakdown in machines, which directly disturbs production process loss of time and cost for technical work. Another important factor is control of quality, which directly depends upon the condition of equipment. Check sheet includes the following points Check Point Details, Standard, Check Method/ Method of Maintenance, Condition/Reading and Remarks. Method of maintenance for each check point been defined as per used for the following research
