S. Suneel Kumar, Associate Professor, VJIT, Hyderabad Electrochemical Machining Process Unconventional Machining Processes Manufacturing Engineering IV- Year Students JNTU, Hyderabad

Out-of-class Activity Design -1 Learning Objective(s) of Out-of-Class Activity At the end of watching the videos student should be able to Appreciate Electrochemical Machining Process. Explain the concept of Faraday’s law of electrolysis. Explain the process parameters, MRR and applications of ECM. Key Concept(s) to be covered Faraday’s law of electrolysis. MRR in ECM process. Applications of ECM in industry.

Out-of-class Activity Design - 2 Main Video Source URL https://www.youtube.com/watch?v=fOc65syJvDM License of Video Standard Youtube License Mapping Concept to Video Source CONCEPT VIDEO SEGMENT DURATION (in min) Introduction to ECM & Process Parameters 0 – 15(v1) 15 Characteristics and MRR 15 – 35(v2) 20 Equipment & Applications 35 – 43(v3) 8 TOTAL DURATION 52 minutes

Out-of-class Activity Design - 3 Aligning Assessment with Learning Objective Learning Objective Assessment Strategy Expected duration (in min) Additional Instructions (if any) Appreciate Electrochemical Machining Process Explain the working principle of ECM. 15 Watch V1

Out-of-class Activity Design - 3 Aligning Assessment with Learning Objective Learning Objective Assessment Strategy Expected duration (in min) Additional Instructions (if any) Explain the concept of Faraday’s law of electrolysis. Talk on Faraday’s law of electrolysis. 15 Watch V2 after watching V1

Out-of-class Activity Design - 3 Aligning Assessment with Learning Objective Learning Objective Assessment Strategy Expected duration (in min) Additional Instructions (if any) Explain the process parameters, MRR and applications of ECM Seminar on process parameters, MRR and applications of ECM. 15 Watch V3 after V1 and V2

In-class Activity Design -1 Learning Objective(s) of In-Class Activity At the end of the class, students will be able to, Understand the importance of ECM as a modern manufacturing process. Analyze the process parameters and MRR of ECM. Appraise the applications of ECM. Key Concept(s) to be covered Faraday’s Law of Electrolysis Process parameters and MRR of ECM

In-class Activity Design -2 Active Learning activity(ies) that you plan to do Concept clarification using. Peer Instruction In-depth understanding using. Debates

In-class Activity Design -2 Peer Instruction Strategy – What Teacher Does Pose the two PI questions at the start of the class and provide summary of basic identities and expression simplification. Q 1: What is/are the suitable electrolyte(s) for ECM process? Kerosene HNO3 Water NaCl

In-class Activity Design -2 Peer Instruction Strategy – What Teacher Does  Q 2: Which of the following are the features of ECM process? a. The electrolyte poses the risk of corrosion to tool workpiece and equipment. b. Only electrically conductive materials can be machined. c. High Specific Energy consumption. d. Both electrically conductive and non-conductive materials can be machined

In-class Activity Design -2 Peer Instruction Strategy – What Student Does For each question they will first vote individually. Then they will discuss with peers and come to consensus. Listen to instructors explanation.

In-class Activity Design -3 Debate Students are divided into 4 groups and given topics to defend and debate upon. For example the following topics were given to the teams. Team 1: Will talk about advantages of ECM process and remaining teams will question and negate/differ the advantages. Team 2: Will talk about disadvantages of ECM and others will negate/ differ. Team 3: Will talk about applications and ECM and other teams will question the applicability. Team 4: Will talk about economics of ECM process and other teams will differ. In this way, in-depth understanding of the concept of ECM is possible.

In-class Activity Design -4 Justify why the above is an active learning strategy In both the above strategies, students are required to go beyond mere listening and execution of prescribed steps. They are required to think deeply about the content they were familiarized in out-of-class and do higher order thinking. There is also feedback provided (either through peer discussion or instructor summary)
