14、塑料注塑成型機(jī) CNC Machining Plastic Injection Mold Plates in theClasss Abstract After finishing their undergraduate educationmany Mechanical Engineering graduates join industryand design parts thatre quire Computer-Numeric-Control(CNC) machining, but too fewgraduates have the knowhowto actually use a CNC

15、machine to produce a complexCNC part. If students were more familiar with the processof programming, fixturing, and running a CNC machine,many of the manufacturing difficulties and costs could be avoided in the design phase. In order to address this issuea CNC machining course has been developed tha

16、t requires students to design and machine plastic injection mold plates for an interesting, unique 3D part. Plastic injection molding was chosen for its prevalence in industry and for the many interesting design constraints that must beovercome when designing for injection molding. This work shows a

17、n innovative, structured, small group approach to teaching the computer aided drafting, machine shop, and design skills necessary to achieve better production part designs. Index Terms Computer-Aided Drafting, Design, InjectionMolding, Machining.QUESTION How do you best teach students the design ski

18、lls necessary tocreate complex computer-numeric-controlled (CNC) parts?INTRODUCTION A CNC mill, figure 1, is a very common manufacturing tool used in industry, however, relatively few mechanical engineering graduates get hands on experience with these machines. Building a CNC part gives student the

19、opportunity to understand the important design constrains of CNCmanufacturing, which then makes them better designers for CNC parts.In order to teach CNC design skills, students built a challenging CNC machining project. Students were required to pick a unique part to produce using plastic injection

20、 molding. Students started with two 6” by 6” by 1” aluminum plates to create plastic injection mold plates. The plates were built to fit into a small production, plastic injection moldingmachine that was used for the course project, Figure 2. Students worked around restrictions such as, wall thickne

21、ss, drafting angles, parting lines, etc. A CNC machine can be used for much more than making plastic injection molds, but this project provided a good hands-on CNC experience that involved many interesting tolerance and design issues. Students work on learning both the computer drafting skills and t

22、he hands-on machining skills necessary to draft and build the mold plates. The overall path of the software and hardware objectives of course can be shown graphically inFigure 3.In order to learn the skills necessary to complete the final project, students completed numerous smaller projects working

23、 towards the overall goal. In order to give the course more structure the individual assignments were grouped into six generalized topics. The six topics were: The manual lathe The manual mill Computer Aided Drafting using SolidEdge Rapid Prototyping for design changes FastCam software for simple CN

24、C projects CamWorks software for more complex CNC partsMANUAL LATHE In order to get students actively involved in the machine shop, students completed a small project using the manual lathe and manual mill. The project chosen for the manual lathe was to build a revolved part that would get used late

25、r in the course. The second day of class, students are given a dimensioned drawing of a lathe part that they must build, Figure 4. Students enter the course with very different machining backgrounds, so starting with the manual machining is necessary to establish a basic understanding of machining p

26、rinciples. Safety is always stressed when learning machining skills. The lathe part is sized such that it fits into a mold plate that makes poker chips. Students will engrave a design ontothe lathe blank before putting it into the poker chip mold. The poker chip design is the first project completed

27、 using CamWorks, which will be discussed in that section. After the lathe project, but still in the first week of the course,students learn to use a manual mill. The manual mill is an important starting point before students try to use a CNC mill. The manual mill offers students the opportunity to g

28、et more feedback than CNC machining. It gives students a chance to listen for machining errors and to feel the forces needed to cut the material (in this case aluminum). Manual machining provides more feedback before errors occur, so its better tolearn basic milling topics using a manual mill before

29、 moving to the CNC mill. The first year the course was offered, students were given a dimensioned drawing of a pencil holder that they cut from an aluminum block, Figure 5. The pencil holder project worked well for teaching basicmanual milling skills, but it was not a very useful part. Students anod

30、ized the aluminum to give it color, but the pencil holders were often discarded shortly after the course. The second year the course was taught, the manualmilling project was changed to a picture frame project. Thegoal of changing the project was to give the students a part that they would want to k

31、eep. Students work harder and learn more if the project is exciting for them and they get invested in wanting their project to turn out well. The dimensioned drawing for the picture frame can be seen in Figure 6 and a finished picture frame can be seen in Figure 7. After students finished the manual

32、 milling of the aluminum frame, the aluminum frames were anodized. After getting anodized blue, the letter engraving was done using a Pinnacle laser engraver, which removed the colored anodized layer.CAD USING SOLIDEDGE In order to use a CNC mill student first needed to learn to usea computer-aided-

33、drafting (CAD) package. Students had experience with drafting, but few had experience with SolidEdge. After a few instructional lectures, students learn SolidEdge and began the process of making a CAD drawing of their expected plastic injection molding parts, Figure 8.After finishing the positive of

34、 the parts, students created themold plates in SolidEdge.RAPID PROTOTYPING In order to help with design, every student was required tobuild their part using Rapid Prototyping (RP). At Rose- Hulman has two rapid prototyping machines available, one using Stereolithography, the other using Fuse Deposit

35、 Modeling (FDM). The rapid prototyped parts clearly showed the student where they might choose to make design changes.Often there were many unexpected design changes made as a result of the exercise. These changes significantly improved the quality of the student part designs and taught students a v

36、aluable design lesson. Some of the Rapid Prototyping parts are shown in Figure 9. On the machining track of the course, students were taught to use the CNC conversational programming mode. The Milltronics company (the brand of the Rose-Hulman CNC machines) uses a program called FastCam for conversat

37、ionalprogramming. While FastCam isnt necessarily the program used by all CNC manufacturers, nearly all CNC machines have some sort of interactive, conversational programming mode that can be programmed directly on the CNC console.The first project that students machined using the CNC mill was based

38、on a simple program that drilled holes to spell their name in wooden blocks, Figure 10. Following the simple holes programs, students made unique wooden plaques, Figure 11. The course started with machining wood, since its cheap and very forgiving of student mistakes. In general, this class used a l

39、ot of small projects to learn machining steps. Students were usually only given a few days to complete the small tasks, as opposed tolarger, more time consuming tasks.CAMWORKS CNC SOFTWARE After completing the numerous intermediate CNC projects using FastCam, students were taught to use CamWorks. Ca

40、mWorks is a program that allows a user to generate tool paths for a CNC machine using a CAD part. CamWorks is avery powerful, user friendly program that works as a plug-in with SolidWorks. The first project students completed using CamWorks was a poker chip design. Students cut a design into their m

41、anual lathe parts and tightened the inserts into a poker chip mold plate, Figure 12. The mold plates were made by Ron Hofmann, the CNC machine shop technician, so students only needed to make the insert design. All of the students made at least one poker chip design and then the students were requir

42、ed to produce plastic poker chips, Figure 13. This also gave the students practice using the plastic injection molding machine before the final project.FINAL PROJECT Both years this course has been taught, every student finished their individual mold plates and ran the plastic injection molding mach

43、ine to produce their parts. In order to create the plastic injection molding projects students needed their CAD skills, CNC machining skills, CamWorks software skills, and plastic injection molding knowledge. Some of thefinal student projects are shown in Figures 14 and 15.ASSESSMENT In order to ass

44、ess the effectiveness of these projects to teach CNC product design a post course survey was given. I. Assessment Methods The survey consisted of six pairs of questions. Each question asked the importance of teaching a topic followed by how well their assignments helped them learn that topic. The si

45、x course topics listed on the survey were: The Manual Lathe The Manual Mill Computer Aided Drafting using SolidEdge Rapid Prototyping for design changes FastCam software for simple CNC projects CamWorks software for more complex CNC partsSession S2A For each question students circled the best answer

46、 for how important a topic was: 1 Very important 2 Important 3 Neutral 4 Not important 5 A waste of time In addition to asking the importance for each of these topics, students were also asked to rank how well the chosen class assignments covered that topic. For the same six topics, students were as

47、ked to circle the best answer, for how they felt about their experience for that topic: 1 Excellent Experience 2 Good Experience 3 Fair Experience 4 Poor Experience 5 A waste of timeII. Assessment Results Out of the 16 students enrolled in the course 14 completed the survey. The average value of the

48、 importance and experience is shown in Table 1.III. Assessment Conclusions The results of this survey suggest that overall students felt the chosen course topics were important and they had good experiences learning these topics. Looking into the specifics of the responses, the lowest two ranking to

49、pics in terms of importance were the Manual Lathe and learning Computer Aided Drafting (CAD) using SolidEdge. Indeed learning to use a manual lathe is not a truly important topic to learn before learning CNC machining. However, in order to finish the poker chip project, studentsneeded to use the lat

50、he to prepare a blank poker chip insert. While not truly a necessary topic, the student average for the manual lathe experience was 4.43, so it was still an interesting learning experience. Additionally the manual lathe makes for a good start to the course and extra machine shop skills are useful. T

51、he second lowest ranking item was learning CAD using SolidEdge. Based on the comments for this question,any low scores came from people that wanted to use SolidWorks instead of SolidEdge. SolidEdge was used primarily because of price. The campus wide license for unlimited SolidEdge seats was much ch

52、eaper than aSolidWorks contract. The two programs are very similar and its very easy to import files back and forth. The lowest ranking experience was the manual millproject. The manual mill assignment given was the trapezoid pencil holder project. Based on this feedback, the second year that project was changed to the picture frame project.IV. Assessment Comments In addition to the six pairs of question there was also a sectio
