BTEB Machinist study guide
BTEB Machinist · Work through your exam, one topic at a time.
The BTEB Machinist credential sits under the Bangladesh Technical Education Board, the government body whose website publishes results, curricula, syllabi and examination regulations for technical education. The board's page identifies its chairperson and secretary and links to separate result portals for diploma, HSC and SSC level examinations. Candidates preparing for a Machinist trade assessment should treat the board's published syllabus, course structure and examination regulations as the authoritative scope document, because the public homepage does not list subject-by-subject content, question counts, marks distribution or pass marks for individual trades. The practical scope of machinist work normally spans four broad areas: machining fundamentals and workshop safety; bench work, fitting and measurement; lathe and machine tool operations; and maintenance, materials and trade practice. The BTEB Machinist study guide has 4 sections and about 1,562 words.
01Machining Fundamentals and Workshop Safety
A machinist must understand how cutting tools remove metal: cutting speed (surface speed, m/min), feed (mm/rev or mm/min), depth of cut, and the relationship between them. Know the difference between speed and feed - a common trap is treating them as synonyms.
