WEEK 5 - METAL BLISTER MAKING

INTRODUCTION

This week, we used a hollow abrasive tool to strike out the middle part of the aluminum sheet in a concave blister shape.

The image shows the final work I have been done in this week.

n the following content, I will show all the steps that how to make the aluminum sheet become a blister.

STEP 1

Firstly, cut the aluminum sheet into a square that will be smaller than the square formed by the four screws on the abrasive tool. Then place the aluminum sheet in the middle of two identical abrasive tools, and fix the abrasive tool with screws so that the aluminum sheet cannot be moved in the abrasive tool.

STEP 2

First, use a metal hammer to strike the middle of the aluminum sheet. By continuous tapping, the entire middle part becomes an arc.

STEP 3

Use the sleek side of the metal hammer to strike the concave part of the aluminum sheet to make it smoother.

STEP 4

Use a pre-designed pointed stick to make the edge of the concave shape more prominent by hammering with a hammer.

STEP 5

Use a big hammer to strike a small hammer to make a partial stroke, making the entire concave part more slick, which the big hammer cannot touch the part near the edge.

WEEK 3 - METAL TORUS MAKING

图片
INTRODUCTION This week we were going to increase the metal making skills, which was creating an aluminum sheet to adhere to the contours of a torus/reversed curve. In this way, to make the aluminum sheet is bent in different directions. The image shows the final work I have been done in this week. Top view Bottom view In the following content, I will show all the steps that how to make the aluminum sheet become a torus. STEP 1 Firstly, make the aluminum sheet is wrapped on a cylindrical abrasive tool and then bent so that the aluminum sheet is tightly attached to the abrasive tool.

By constantly moving, make the middle portion of the entire aluminum sheet is recessed and two sides are kept i

INTRODUCTION This assignment will carry out a targeted analysis of some of the tasks that have been completed before, summarizing the existing problems, and then giving the best solutions to the emergent stages according to the problems. Through analysis and summarization, I can learn more about what I have learned at this stage. BRIEF REVIEW Project 1 - The foundation study of making different metal shapes. Through the first half of the semester, we learned to use different methods and equipment to make different shapes of metal. At the same time, we can explore the different shapes in the production process, so that the shape of the metal can be as we expected.  In project 1, we were allowed to exercise shape-making techniques by making different shapes. At this time, we learned more about using different tools and metal production equipment in the workshop. On the other hand, the complex shapes in project 2 can be better prepared by the learning in project 1. Project

WEEK 2 - METAL BOWL MAKING

INTRODUCTION This week we were going to use a 200mm x 200mm aluminum sheet that strike it to became a metal bowl. follow this project, we were going to learn how to use the basis way to change the metal shape. The image shows the final work I have been done in this week. Bottom view Top view In the following content, I will show all the steps that how to make the aluminum sheet become a bowl. STEP 1 I am going to use the laser cut machine to cut the bass wood, which going to be the bowl template consisting of a series of concentric rings. Concentric rings Then create a "radius gauge" to help guide and evaluate the progress. It will be use later. Radius gauge STEP 2 Using the c oncentric rings to draw the sign on the  aluminum sheet , which we can clearly to see the part we need to strike. Draw the sign the metal Finishing work STEP 3 I am going to use the metal cutter follow the sign to cut the aluminum shee
