Definition CAPP (Computer Aided Process Planning)

CAPP (Computer Aided Process Planning) is a system developed for the resolution of the complex process baking task.

It is the act of preparing detailed operating instructions to convert an engineering design into a final piece of information.


The following cost savings list is from a study of several companies:

  • 58% effort reduction planning process.
  • 10% savings in direct labor.
  • 4% savings in material.
  • 10% reduction in scrap metal.
  • 12% savings on supplies.
  • 6% reduction in work in process.

Variant Approach

Also, there are intangible benefits, as follows:

  • Quick response to engineering changes.
  • Updated information in a central database.
  • Improved cost estimation procedures and fewer calculation errors.
  • More complete and detailed process.
  • Ability to introduce new technology.
  • Reduces work in progress.

They divide the parts based on design and also manufacturing attributes. These pieces are familiar as masterpieces.

The work plan for the part is created by recalling, identifying, and retrieving an existing design for identical parts and making modifications necessary because of a new piece.

  • If the planner makes a mistake in the classification and coding (TG), there will be no quality process plan.
  • It gives efficient elaboration and control through the reduction of resources.
  • It creates standardized procedures, which helps better knowledge.
  • Lower cost of software creation and also
  • Generative Approach


Plans get generated using decision logics, formulas, technological algorithms, and geometry-based data to convert a part from raw material to a finished state. They store manufacturing rules and equipment capabilities on a computer when used; a process plan gets produce without the involvement of a process planner.


  • Keep updating logic rules.
  • It gives higher application and installation costs than a recovery CAPP.
  • It is fully automatic.
  • They provide more accurate, consistent, and economic results.
  • Less dependency on the planner.
  • They need less effort to maintain and update process plans.
  • Automate process planning and job preparation.
  • Integrate CAD and also CAM for effective production.
  • Establish process plans.
  • Reduce human resources for planning tasks and also
  • Optimization of resources (time, supplies, labor, etc.)

CAPP systems have been evolving temporarily and also technologically, starting from the traditional/manual approach towards the two traditionally recognized approaches: the VARIANT and the GENERATIVE. Today, most of these systems have characteristics of a combination of both.


Select and define, in detail, the process that must run to transform raw material into a given shape. The primary objective is to define feasible methods. Cost and production are secondary objectives, and also the available resources (machine tools, cutting tools, and work) act as constraints.

Since the 1970s, the manufacturing environment has become more complex and competition has become more intense; therefore, process planning has become a critical factor in the success of many companies.

Some companies already had an Integrated Computer Manufacturing (CIM) system in the early 1980s to improve the collection, analysis, and use of plant information. By the end of the decade that Computer Aided Process Planning or CAPP was built, which integrates the CIM systems, particularly CAD and CAM, with plant control systems.

CAPP software

Microsoft Project (or MSP) is project management software designed, developed, and also marketed by Microsoft to assist project managers in developing plans, assigning resources to tasks, tracking progress, managing budgets, and analyzing workloads.

TOTVS concentrates its efforts on developing services and solutions that meet the specific needs of each client. Much more than just tools, TOTVS solutions and services represent real advantages for better company management.
