Process sheet is a set of manufacturing instructions for a specific batch, lot or runs. It describes the operating parameters and settings for the equipment and facilities used. And also associated tooling or supplies.
It contains part information, routing information and operation detail information.
We all know what a blueprint is and how it works; so trust me when I say a process sheet works exactly like a blueprint. This article finds out all about process sheets and how they are done.
Process sheet is a set of instructions that can be followed to achieve the desired goal. It is a manual that involves detailed procedures of tasks.
This rule book actually focuses on converting the raw materials into the final finished product; getting the job done in a systematic manner.
It not only outlines the detailed mechanisms but also describes each and every event in a step by step manner. This is where the importance of the manufacturing process sheet lies.
Firms with infrequent productions, a complex production pattern or elaborate and irregular steps are required to follow a process chart efficiently.
In fact, the process sheet is developed way before a firm actually starts operating. This helps in having control over operations from day one.
The components outlined in a process sheet
A process sheet for machining comprises of two units,
- A route sheet.
- A process sheet.
A route sheet is like a map that mentions the path to be followed, and exactly how the production and management activities were to proceed. A process sheet not only mentions the step by step programs to be followed but also one which outlines all the materials required for each task, maintains a logbook of items arrived or yet to arrive.
It is an irreplaceable tool. It actually keeps a tab on the entire work process for which it has been designed. It keeps a count on the amount of raw material required, total processing time taken, the number of workers, specifications of the machines functioning, and so on for every separate component involved in the production.
For example, a process sheet documentation designed for preparing a food item would not only consist of the recipe, but also each component mentioned in the exact quantity required. It will also consist of cooking time with a detailed description of each task, the number of workers required in each task, and also if any remarks are needed to be followed, by previous experiences.
Structure of a typical process sheet for manufacturing
- Outlining the sequence of work.
- Figuring out the assemblies and sub-assemblies involved and drawing a map to figure out where each one fits.
- Determining the number of units to be produced.
- Machines, tools, and details of other instruments required, along with other details like their efficiency, capacity and run times to be mentioned.
- The sequence of these operations, drawn in detail on a map which develops a clear conception of how the raw material is converted into the finished product.
- A certain quality is required throughout the process; hence quality controlling instructions are also important.
- Instructions during packing and handling of the products, or movement during the processing are also mentioned.
A process sheet for production drawings can be used for various purposes. A separate sheet can be made for different operations.
It can be used as a planning tool to plan wisely and efficiently, and also as quality control.
Different departments can monitor operation for various purposes, at the same time, thus developing an economically efficient plan and seeing it succeed through skillful execution.
