Introduction
Route sheet or process sheet is the map or the blueprint of the manufacturing process in a production unit, providing the precise route or sequence to be followed. A processsheet describes the series of actions to be performed to achieve a particular task in the manufacturing or production process. Thus, a process sheet is a document which has information and instructions for converting raw materials into finished components or specific assembly; containing details such as material requirement, date and time, remarks, log in/out, etc.
Process sheets are essential for efficient planning to perform
manufacturing sequences in an economical way. Different process sheets are
prepared for different parts keeping in requirement of the components,
equipment availability; their capacity and run time, number of skilled work
force available, etc
A typical process sheet contains the following information:
- Identification
and sequence of work arrangement.
- Drawing
of part, assemblies or sub-assemblies of the product
- Estimated
number of units to be produced.
- Machines,
tools, jigs and fixtures used in the operation, their run time, efficiency
and capacity.
- Operations
needed on the given part.
- Sequence
in which these operations are performed.
- Inspection
and quality assurance requirements.
- Packing
and handling instructions during movement of components through the
operation stages.
Process sheets can be applied in different ways. They may be used
as planning tools, and for quality control purposes. When used as planning
tools, a process sheet may be used by different departments as they set up the
step by step production of an item. Different supervisors and managers are able
to monitor progress, production time, equipment use, and operator history
throughout the production process using the routing sheet. Therefore, a
process-sheet can be used during planning, production, monitoring, and quality
control for an item or items during the manufacturing process
