MACHT 201 is designed to get you started in the basics of machining. In the learning process, you will acquire the basic skills of the most prevalent machines available in the industry, starting with the engine lathe, vertical milling machine, pedestal grinder, drill press and surface grinder.
By the end of the course, you will have completed three projects, which are designed to slowly build your confidence on the machines while acquiring new skills.

MACHT 202, a follow up course, continues to build on your previous experiences by providing more difficult projects where expectations in accuracy are also higher. Manufacturing procedures will be of your own design. Blue print reading and interpretation is strongly reinforced.

MACHT 203 - In your third semester of study, you will be acquainted with support equipment of the industry, as well as outside processes. New set-ups and operations for the lathes and milling machines will be learned. Set-ups for medium size production will be utilized. Application of algebra and trigonometry will become imperative for the manufacturing of the projects.
Attend workshops on workforce preparation and résumé writing.

MACHT 204 builds on the foundations necessary for computer numerical control (C.N.C.). Emphasis is placed on techniques for mass production. The coordinate system, "G" codes and "M" codes will be thoroughly understood. Projects are completed with minimum assistance.
4th semester students must have an updated résumé on file.

GENERAL NOTES FOR MACHINE SHOP------ALL CLASSES

1. Broken, damaged, or dull tools must not be returned to the Tool Crib. These items are safety hazards.

2. Each piece of equipment will be cleaned thoroughly, sliding surfaces re-oiled and the surrounding area swept clean at the close of each class session or upon completion of its use. Sweep up and pick up ALL of your chips and dirt.

3. Return all tools to the TOOL CRIB, not your locker.

4. There is no need to interchange the tool holders on the lathes. If any one of them does not work properly, turn it in to your instructor so that it may be repaired or adjusted. Make NO repair or adjustment yourself unless specifically instructed to do so.

5. Your highest degree of cooperation is needed in order to keep the steel stock rack in order.

6. Be sure to store ALL equipment and steel stock, no matter how heavy or light, in a safe and secure manner.
It may be your foot that it will fall on if not stored properly. Observe good safety practices at all times.

7. In ANY instance, if there is anything you do not understand thoroughly, do not hesitate to ask your instructor.

8. Each machine has a lube oil can painted red in a holder in a convenient position on the machine.
This is for lube oil only. When the can is empty, fill it up!

9. Do not change the FEED rate on the power hacksaw. Use this piece of equipment with great care as the blades are quite expensive.

10. Report the malfunction of any piece of equipment to your instructor.
Do not attempt any repair yourself unless specifically instructed to do so.

11. Do not abuse any piece of equipment. Use it, but do not abuse it. If you are unsure how to use a certain piece of equipment, ask your instructor. Maintenance service is expensive and very difficult to obtain.

12. Use cutting oil very sparingly.
It has NO cooling effect unless applied in a flood or stream. Do not let your work area look like a big bird has taken a bath in cutting oil! Excess use of cutting oil creates a very serious safety hazard.

13. NEVER, UNDER ANY CIRCUMSTANCES, are you to leave a cutter in an adapter or a cutter on an arbor. This creates a very serious safety hazard. Fly cutter heads are to be removed from spindles and adapters.

14. Cut only steel stock that is color-coded Brown and White or Blue unless given specific instructions from your instructor.

15. Be positive that you are using the correct blade, the correct speed, and the correct feed when using the band saw. This machine is to be cleaned thoroughly after each use.

16. Milling machine vises will not be used as drill vises.

17. Dividing heads, rotary tables, end mill adapters, arbors, etc., must be returned to their respective storage areas after their use or at the close of each class session. We do not have servants in this shop!

18. AT NO TIME NOR FOR ANY REASON, will any material other than CARBIDE be ground on the CARBIDE grinding wheels. Do not grind on the rim of these wheels; use the face only.

19. Non-ferrous material will not be ground on any grinding wheel. Materials in this category include: aluminum, copper, brass, plastic, rubber, and wood.

20. No equipment, tools, or material of any kind will be left on the shop carts or wagons. Clean them off after each use or do not use them. Return the carts and wagons to their respective storage areas after each use so that they may be readily found when needed.

21. NO TOOLS OR EQUIPMENT belonging to the college will be placed in your locker.

22. Bring safety hazards to the attention of your instructor or correct the hazard yourself. You may be the victim of this safety hazard.

23. Keep the lathe quick-change head as far to the left of the compound slide “T” slot as is practical. This helps prevent machine damage, breakage, and several other unpleasant problems.

24. Tools being returned to the tool crib will be placed in the proper storage space. If you do not know where this is, or cannot see where a tool belongs, ask your instructor.

25. Blueprints and Process Sheets must be returned to the “Blueprint File” at the close of each class.

26. Scrap metal and chips only are to be place in the containers by the machines. Do not put paper or rags in these containers.

27. It is imperative that no rags, steel stock, or other material be wasted. Waste of anything brings on shortages or a “furnish-it-yourself” situation.

28. Personal projects will be stored in lockers only. No other storage space is available in the Machine Shop.

29. If you choose to use a lock on any locker in the Machine Shop, you will ensure that a key of the combination is on file in the Shop office. This is your responsibility! Locks without keys or combinations on file are subject to removal.

30. Use of drugs, alcohol, or other hazardous substances while in the Shop or before coming to the Shop will be cause for immediate dismissal.

31. Finger rings and wristwatches may not be worn in the Shop.

32. Open toe shoes, including tennis shoes and thongs, may not be worn in the Shop.

33. Safety glasses will be worn at all times in the Shop.

34. Long hair will be tied back or otherwise secured to the satisfaction of the instructor in charge.

35. PLEASE DO NOT STEAL OUR TOOLS! We do not have the money to replace them! When a tool is stolen, please remember that you are depriving many other students of the use of this tool. Class fees may have to be raised in order to help pay for “misplaced” items! Also, remember that it is entirely possible that you may be required to furnish more and more of your own tools!
