History of iso casting standards
Since its inception in the late 1940s, the International Organization for Standardization (ISO) has played a pivotal role in the development and advancement of numerous international standards. Among these is the ISO 9000 family of quality management systems (QMS) standards, which provides guidance and requirements for organizations that want to implement a QMS.
The first ISO 9000 standard, ISO 9001, was published in 1987 and has since undergone several revisions. The most recent version, ISO 9001:2015, was published in September 2015.
The ISO 9000 family of standards is divided into three categories: Fundamentals and vocabulary, Quality management systems requirements and Quality management systems guidelines.
The Fundamentals and vocabulary category includes the following standards:
- ISO 9000:2015 – Quality management systems – Fundamentals and vocabulary
- ISO 9004:2009 – Managing for the sustained success of an organization – A quality management approach
- ISO 19011:2011 – Guidelines for auditing management systems
What is casting tolerances
Casting tolerances are part of the process when creating manufactured parts from metal, plastic, or other materials. In this precision process, dimensional accuracy must not stray beyond a certain threshold for the part to be considered successful.
The tolerance range is created prior to casting to ensure any product will meet design requirements and serve its intended purpose, such as a vehicle fitting properly with another part made by different processes.
To make sure this occurs, fine-tuned calculations are made and manufacturing on a larger scale is adjusted accordingly. The skills needed to develop accurate tolerances require an individual with good technical knowledge and understanding of production-machine capabilities.
What is dimensional tolerances
Dimensional tolerances are very important in the world of engineering. They are the set values that allow a certain amount of deviation from the given design specification when making parts or components. Dimensional tolerances must be considered when assembling components into larger units or systems, to ensure that each component functions properly when put together.
Without dimensional tolerance specifications, engineers and manufacturers would have much greater difficulty in constructing items that meet desired standards and performance criteria. Using appropriate dimensional tolerances can help minimize costs and maximize production efficiency by reducing the time it takes to assemble a component or system.
As such, proper knowledge and understanding of dimensional tolerances is critical for any engineer working on designing products that function correctly and effectively.
