What is variant process planning?

What is variant process planning? The variant approach involves retrieving an existing plan for a similar part and making the necessary modifications to the plan for the new part. The generative approach involves generation of new process plans by means of decision logics and process knowledge.

What are steps to variant process planning? Steps involved in VARIANT CAPP are as follows:
Define the coding system.
Group the parts into part families.
Develop a standard process plan.
Retrieve and modify the standard plan.

What are the types of planning processes? The types are: 1. Manual Process Planning 2. Automated Process Planning 3. Generative Process Planning.

What is CAPP in manufacturing?

Computer-aided process planning (CAPP) is the use of computer technology to aid in the process planning of a part or product, in manufacturing.
CAPP is the link between CAD and CAM in that it provides for the planning of the process to be used in producing a designed part.

What is a variant approach?

What are 4 types of planning?

There are four types of planning. Each type of plan commits employees within different departments and their resources to specific actions. While there are many different types, the four major types of plans include strategic, tactical, operational, and contingency.

What are three types of planning?

There are three major types of planning, which include operational, tactical and strategic planning.

What are the 5 steps in the planning process?

Execute and manage your plan.
Review and revise the plan.

What is need planning process?

Process planning is a preparatory step before manufacturing, which determines the sequence of operations or processes needed to produce a part or an assembly.
This step is more important in job shops, where one-of-a-kind products are made or the same product is made infrequently.

What are advantages of planning?

Planning helps in reducing uncertainties of future as it involves anticipation of future events. Although future cannot be predicted with cent percent accuracy but planning helps management to anticipate future and prepare for risks by necessary provisions to meet unexpected turn of events.

What are the objectives of planning process?

To provide specific direction • Planning provides a specific direction for doing various activities in an appropriate manner. 5. To bring economy in managerial operations • It is an important objective of planning. Planning provides a proper guidance to an organization how to bring economy in all around operations.

What are types of CAPP?

There are two approaches for computer aided planning process: retrieval type CAPP systems and generative CAPP systems. Both these systems have been described below. In the retrieval type of CAPP system the various parts to be manufactured are classified, given codes and grouped within certain families.

Where is Capp used?

Commonly used by manufacturing engineers, CAPP can be used to develop a product manufacturing plan based on projected variables such as cost, lead times, equipment availability, production volumes, potential material substitution routings and testing requirements.

What are the advantages of CAPP?

Advantages of CAPP and there future trends.

Reduced process planning and production lead-times.

Faster response to engineering changes in the product.

Greater process plan accuracy and consistency.

Inclusion of up-to-date information in a central database.

Improved cost estimating procedures and fewer calculation errors.

What are the advantages and disadvantages of manual process planning?

10.
4 Advantages and disadvantages of manual process planning.
The only real advantages of manual process planning are that it is a low-cost task and is flexible, in terms that the system can be changed easily.

What are the factors affecting process planning?

The following information is needed to develop a process plan.
Knowledge of Various manufacturing processes.
Engineering drawing of the component.
Knowledge of various tooling and fixtures.
Relative costs of various processes, tooling and raw materials.
Resources available in the factory.

What is the difference between a variant system and a generative system in computer aided process planning?

Two approaches to computer aided process planning are defined—variant and generative.
The variant approach retrieves existing plans for a similar part while the generative approach synthesizes plans from built-in knowledge.

What is manual process planning?

Manual process planning is based on a manufacturing engineer’s experience and knowledge of production facilities,equipment, their capabilities, processes, and tooling.
Process planning is very time-consuming and the results vary based on the person doing the planning.

What are the elements of computer integrated manufacturing?

Computer Integrated Manufacturing (CIM) system has several key components: an automated storage and retrieval system (ASRS), at least one automated workstation such as CNC machining, a continuous-loop conveyor, a central management control station, a TCP/IP communication network, and OpenCIM software.
