Boa noite pessoal.
Estava navegando na internet a procura de informações e idéias para o meu torno south bend (aqui no Brasil não se encontra absolutamente nada sobre ele ) e deparei com este site .

http://www.metalworking.com

Tem muita (mas muita mesmo) informação nele.
Ainda não vi nem 1/10 mas achei uma série de manuais muito interessantes.
No apêndice por exemplo temos várias tabelas e aquelas fórmulas de área, dimensão e volume de sólidos que quando precisamos......... .. esquecemos como era .

Abaixo os links.
