Old Colony Machine Tool & Technology
Junior /Senior Shop
Around the shop we have added new tooling and equipment. Machine & Tool now has a CMM (Coordinate Measuring machine) thanks to a donation from Autocam Medical of Plymouth. The CMM will allow students to inspect their work using cutting edge industry standard equipment. Autocam also donated a box of carbide end mills. We have added to our CNC tooling, adding Cat40 tool holders and ER collets. Machine students are part of an integration project with Metal Fabrication and CAD, we are doing a design build project for an outside customer.
The junior class has been busy on multiple projects, the vise stop, tap wrench, 123 blocks, Millpower programing and N.I.M.S. Several students are moving along on the tap wrench. One student has only the jaws to make and the project will be complete. Students are programing in G & M code and machining the 123 blocks in the Haas machining center. Three students have completed the programming, machining, and heat treatment of the 123 blocks. All students have programed multiple jobs in the CNC Mill Power milling machine using conversational programming. The NIMS shop Layout and the Bench work tests have been passed by all students.
Juniors are now eligible for Co-Op and once again jobs are abundant. Three juniors are on Co-Op, one at Auto Cam Medical in Plymouth and 2 are at AA Precision in Fall River.
The senior class all programed and machined their name using G&M codes. Students are programing in G & M code and machining the T slot cleaner in the Haas machining center. Two students have completed the programming and machining. All students have programed multiple jobs in the CNC Mill Power milling machine using conversational programming. Portfolios are being updated in preparation for graduation.
Once again the Machine & Tool job market is great for our Co-Op program. Three seniors are on Co-Op at Auto Cam medical in Plymouth, one student is at AA Precision in Fall River and one student is at RM Machine in Fall River. Employers are happy with all our students and have taken some juniors.
We would like to welcome our Freshman Class of 2019 to Machine & Tool Technology. The first day of the shop cycle was spent getting to know each other a little better, and reviewing the shop policies, rules, and procedures. Of course safety in our shop is of the highest priority so naturally a refresher was revisited. Each member of the class machined a spring center as their first project and all turned out well. The second project the class completed was a hardened center punch that exposed them to a couple of new processes, namely knurling and heat treating. By the start of the second week of the shop cycle the class had moved onto their first major project, the miller Jack. This project will introduce the class to turning between centers, taper turning, single point threading, and some basic milling setups.
A list of necessary shop tools has been sent home for students to purchase.
The sophomore class is working on their vise project. About half of the class should finish this by the end of the trimester. The remaining should finish by the end of their next shop cycle. Their next major project will be the mill table stop. Sophomores will also be taking their benchmark tests this spring. Sophomores will also start machining some practice pieces that will sharpen their skills in preparation for NIMS testing which will take place during their junior year.
A form for T-shirts and sweatshirts will be passed out in the very near future for students to place an order for shop attire.
At this point the freshmen have settled into the Related class well. Classroom rules have been established and we seem to have a mutual respect for one another. All have the required binders along with the essentials list that was sent home earlier this month. For coursework completed, they have had general shop safety tests and are continuing to learn the safe operation of engine lathes. One of the first theory chapters we learn regards tapers and threads. Students learn how to apply algebraic formulas to real shop problems. After that we cover threads and how to cut them on engine lathes. The scientific calculator comes in handy at this point
The sophomores have had a busy year so far. In the first trimester, they have reviewed safety in the shop and on specific equipment to remind them how important it is to be aware of their surroundings while working. Related theory lessons in layout, measurement, engine lathe operation, offhand grinding, hand and mechanical saws and hand tools have been covered. Blueprint reading units in orthographic projection and isometric views is an ongoing process. Another topic we have worked on is shop mathematics. Cutting speeds and feederates for specific tools and materials has been completed. However, it is an ongoing process while machining parts and projects in the shop.
The junior year is a tough one with several state and national tests and the opportunity of co-op. The junior class has started the year with several tough chapters of Related Theory. The following have been covered precision grinding, geometric dimensioning and tolerancing, jigs and fixtures. As for blueprint reading, we have covered auxiliary views, decimal dimensions and tolerances and dimensioning angles. Another topic to add to the mix is exposure to computer numerical control better known as CNC programming. A huge accomplishment by the entire junior class is they all earned their OSHA 10 hour General Industry and Health certificate. Those tested have passed the national NIMS level 1 written test and nine students have passed the level 1 MACWIC (Manufacturing Advancement Center Workforce Innovation Collaborative) state manufacturing test.
MACWIC is currently in negotiations with community colleges and state universities to offer college credit to those students pursuing higher education in the manufacturing field.
The senior class has a different challenge. Many are on co-op and miss some time in the Related Theory program. One way to qualify what they are learning is to complete a co-op cycle reflection giving a written narrative on their time on the job. The students highlight what they have learned as well as include a picture of a product or piece of equipment they have worked or trained on. Aside from that the chapters in Related Theory covered are quality control, electro machining, non-traditional machining, gearing, dividing heads and automated manufacturing. As for blueprint reading we have covered the following, various hole descriptions such as counter bores counter sinks, spot facing, dimensions and tolerancing, fillets, rounds and slots and machining symbols. Exposure to CNC programming continues with G and M code writing where we will create part programs in the Related Theory class and machine the parts in the shop
