| The
Automation Cycle
- A
company may identify potential for automation whilst undergoing
a yearly review of existing plant and projected orders.
- Perhaps
a critical process has inherent problems and a solution must be
found to eliminate a bottleneck in the production process.
- A
new product may be coming on stream which requires a revolutionary
approach to the manufacturing process.
- A
start up product may be proving so successful that production
volumes require a fresh approach to manufacturing methods.
Having
identified a specific need to solve any of the above problems (amongst
others), the process begins.
The
first step and the most important as far as the purchaser is concerned,
is to establish a reference point or datum, known as 'The Project
Specification'.
When
the product Spec has been accurately defined and internally approved,
it can be used to investigate automation potential.
This
should produce, in conjunction with external suppliers, a variety
of possible solutions.
The
next stage is to examine the pros and cons of the proposed solutions,
and determine the most suitable approach.
Simulations
and workflow analysis can be used to test proposals. This should
help to establish performance under variable conditions.
Assuming
12 weeks to carry out the preparatory work, and 12 weeks to undergo
the budgetary and firm phases of the bidding process, it can be
assumed that 24 weeks should take us to the point of order placement.
A realistic build schedule for a simple robot cell will be in the
order of 24/28 weeks, so the minimum automation cycle will be in
the region of 1 year from start to commissioning and sign-off.
A well
ordered installation with good project management should enable
an automation cell to be installed and commissioned in 2/3 weeks,
from start to finish. This assumes a high level of build and minimum
dismantling at the suppliers facility, prior to shipping.
