INTRODUCTION TO PROCESS PLANNING
2 – marks question and answers
1. What is process planning?
Process planning is the systematic determination of how a product is to be manufactured economically and
competitively. It involves deciding the sequence of operations, selecting equipment and tools, and
specifying the processes needed to transform raw materials into finished products. Essentially, it bridges
the gap between product design and the manufacturing process.
2. Mention the methods of process planning.
There are three main types of process planning: manual process planning, computer-aided process planning
and generative process planning.
3. List the major functions of process planning.
To determine the basic manufacturing process.
, To determine the sequence of operations.
To determine the equipment's and tooling required.
4. What are the factors affecting process planning?
Process planning is influenced by several factors including the product's functional requirements,
production volume, necessary operations and their sequence, available tools and equipment, and the
characteristics of the materials used. Other important factors include the available resources, cost
considerations, and the overall production environment.
5. Why is process planning important in tool engineering?
When done right, process planning helps manufacturing engineers design for manufacturing, develop
processes that align with the design intent, meet quality requirements, and manage as-built configuration.
6. Why is it important to evaluate materials?
Evaluation of learning materials serves several important purposes: Quality Assurance: Evaluation ensures
that the learning materials meet established standards of quality, accuracy, and relevance. It helps maintain
the credibility and integrity of the educational content.
7. What are the 7 steps in the planning process?
Step 1: Develop Objectives.
Step 2: Develop Tasks to Meet Objectives.
Step 3: Determine Needed Resources.
Step 4: Create a Timeline.
Step 5: Determine Tracking and Assessment.
Step 6: Finalize the Plan.
Step 7: Distribute the Plan to Team.
,8. What are the functions of jigs and fixtures?
Jigs and fixtures are indispensable tools in modern manufacturing, playing a crucial role in ensuring
precision, consistency, and efficiency in production processes. These specialized devices are designed to
securely hold, guide, and support workpieces, enabling machining and assembly.
9. What is the route sheet?
In process planning, a route sheet is a document that outlines the sequence of operations needed to
manufacture a product, including the machines and resources required at each step. It acts as a roadmap for
production, ensuring each part or product is fabricated according to the planned process.
10. 1. List the material selection parameters in process planning.
2. In process planning, material selection parameters encompass factors like functional requirements,
appearance, reliability, service life, environmental conditions, compatibility, productivity, and cost. These
parameters ensure the chosen material is suitable for the intended application and manufacturing process.
13 and 15 marks question and answers
11. Explain Methods of process planning.
, Process planning methods involve a structured approach to determining how a product or service will be
created, delivered, or executed. These methods aim to optimize efficiency, reduce costs, and improve
quality. They can be broadly categorized into manual, variant, and generative approaches, each with its
own strengths and applications.
