Benefits of CIM

1.CIM improves the short run responsiveness consisting of :

• Engineering changes
• Processing changes
• Machine down time or unavailability
• Operator unavailability
• Cutting tool failure
• Late material delivery

2.CIM improves long run accommodations through quicker and easier assimilation of :

• Changing product volumes
• New product additions and introductions
• Different part mixes

3.CIM reduces inventory by

• Reducing lot sizes
• Improving inventory turnovers
• Providing the planning tools for Just – in Time manufacturing

4.CIM increase machine utilization by :

• Eliminating or reducing machine setup
• Utilizing automated features to replace manual intervention to the extent possible
• Providing quick transfer devices to keep the machines in the cutting cycle.

Some quantifiable benefits achieved by apply CIM are :

• Engineering design costs can be reduced by 15 to 30 %.
• The overall lead times can be reduced by 30 to 60 %.
• The product quality can be increased dramatically, as measured by the yield of acceptable product, offering 2 to 5 times the previous level.
• Productivity of the manufacturing operations can be increased by 40 to 70 %.
• Operating time related productivity can be increased by 2 to 3 times.
• The productivity of engineers and engineering managers can be increased by 5 to 35 times, measured in terms of extent and depth of analysis in the same or less time.
• Work in process can be reduced by 30 to 60 %.
