thickness variation
[ˈθɪknəs ˌvɛriˈeɪʃən]
nounpl: thickness variations
variação de espessura
1. The difference or inconsistency in the measurement of thickness across a material, object, or surface
The thickness variation in the metal sheet made it unsuitable for precision manufacturing.
A variação de espessura na chapa de metal a tornou inadequada para fabricação de precisão.
2. In manufacturing and quality control, a tolerance deviation from a specified uniform thickness standard
Quality inspectors flagged the thickness variation in the plastic film as exceeding acceptable limits.
Os inspetores de qualidade sinalizaram que a variação de espessura no filme plástico excedia os limites aceitáveis.
3. In materials science and engineering, fluctuations in material density or structural consistency
The thickness variation observed in the composite material was attributed to uneven cooling.
A variação de espessura observada no material composto foi atribuída ao resfriamento desigual.
This is a technical term predominantly used in manufacturing, quality control, and engineering sectors in both Brazil and the USA. In Brazilian industrial contexts, particularly in São Paulo's manufacturing hub, adherence to thickness variation standards is critical for export-quality products. The term reflects the global importance of precision manufacturing and is used consistently across Portuguese and English-speaking technical communities.
