Geometrical Dimensioning And Tolerancing Application Project

This project was undertaken to:

  1. Increase the awareness of geometric tolerancing for the delegates

    Correctly display geometrical tolerancing company X production drawings

    Functionality deriving manufacturing tolerances

    Bring down costs within design, manufacturing, quality and assembly

    The Project consists of five delegates, first of all they went through the foundation training to uniformly understand geometric tolerancing as a communication tool. Then two application sessions were created using similar type components which were derived by Seize A Solution Limited, to take the delegates through a step by step procedure to derive the functional tolerancing. Following the application sessions the delegates then worked on their part of the assembly and a one to one mentoring session was undertaken. We then held a drawing review day where the drawings were scrutinised by the team and changes made where needed.

    Results we are as follows:

  2. The time taken by the designer to complete the drawing increased by one week.

The design drawing went out right first time without interpretation problems.

Tolerances used to define the components were well within the manufacturing capabilities of the machining department.

The quality department use conventional instruments to measure the components.

The manpower and the time taken to assemble the components was drastically reduced

Costs:

Initial fundamental training: five days 3750

Two applications sessions: four days 3000

Mentoring sessions: three days 2250

Drawing review: one day 750

Project Total 9750

Savings:

Manufacturing time to cut down by 25% 30000 per year estimated

Amount of shims used in the assembly 1500 per year estimated

Reduction of one assembly engineer 43200 per year

Warranty claims down by 75% Confidential Amount

Overall Saving in the first year 64750 without including warranty claims.
