mech140 BASICS OF MACHINE TOOLS (BMT)

COURSE OUTLINE

Course Instructor:  Kasra Shafizadeh | kshafiza@sfu.ca

Requirements:  

  • Completion of the Shop Safety Training course provided by SFU or equivalent organization.
  • Fundamental understanding of material properties and compositions.
  • Proficiency with basic hand and power tools.
  • Basic knowledge of orthographic views and CAD design.
  • Preliminary understanding of fits and tolerances.

Description:
“Safety, Hands-on Experience and Fun”.  This training workshop focuses on hands-on experience with basic hand and power tools, along with acquiring practical skills in conventional lathe, mill operations, and standard machine shop equipment usage. Participants will also learn essential measuring techniques and devices. By the workshop's conclusion, attendees will grasp basic machining theory and be capable of executing fundamental machining tasks and other shop practices. These skills are crucial for mechanical design, prototyping, and future fabrication projects.   Furthermore, this workshop serves as a prerequisite for advanced training programs such as "Basics of CNC Machining," which delve into professional-level machining and fabrication skills. Successful completion of the SFU safety course (or equivalent) is a mandatory requirement for participation in this training program.

Organization:
The workshop will be structured as follows:

  • Participants will receive a blend of theoretical knowledge and hands-on experience.
  • Classroom sessions will cover machine descriptions, the functioning of machine components, basic mathematical calculations for feed and speed, and procedures for using hand-tools and bench-work techniques.
  • In the state-of-the-art "Mechatronic Machining & Testing Centre," participants will work directly with real machines and tools. Approximately 80% of their time will be dedicated to practical exercises, ensuring they acquire fundamental skills aligned with the workshop's objectives.

Objectives:

  • To acquire practical machine shop skills and expertise.
  • To educate participants on the fundamentals of commonly-used machines and tools, equipping them with theoretical knowledge necessary for conventional machine shop work.
  • To provide participants with industrial standards essential for mechanical design, prototyping, and subsequent project fabrication.

  • The workshop will include demonstrations on the use of measuring instruments, work planning, layout techniques, and bench work procedures.

General and Shop Safety Rules:

  • Cellphones, headphones, and EarPods are prohibited due to the risk of distraction, which is the leading cause of injury in the machine shop.
  • No food or drinks are allowed in the workshop area.
  • It is mandatory to clean and tidy up the machine workspaces and the entire shop at the end of each workshop day/session.
  • Proper PPE (Personal Protective Equipment) must be worn at all times, including safety glasses, closed-toe shoes, and appropriate clothing. Loose clothing, shorts, slippers, jewelry, and untied long hair are not permitted.
  • Strict adherence to safety guidelines and instructions is required, including signing a disclaimer agreement before entering the machine shop.
