Reverse part drawings and part manufacturing
Introduction
When you have trouble with an old machine, the most common problem is repairing broken parts.
If a blueprint for the part exists, it can be used to recreate it, but with older machines, blueprints often do not exist, and many people give up on repairs at this point.
In such cases, we can use reverse engineering to create a blueprint of the part and reproduce it, but because reverse engineering is different from repair, there are a few differences from the general image.
In this column, we will introduce some of these points.
1. The price is higher than repairs
Creating a parts diagram through reverse engineering begins with investigating the mechanism, environment, and intended use of the part or machine.
Based on this information, the parts are redesigned, drawn up, and manufactured, so unlike repairs, design costs are inevitably incurred. Therefore, in most cases, creating part drawings and manufacturing parts through reverse engineering is more expensive than the price you would expect for a regular repair.
2. It is impossible to make exactly the same parts
Reverse engineering involves investigating the current state and redesigning the necessary parts. Even when creating drawings based on existing parts, the reverse engineering is still based on the actual part. Since the original drawings are not restored, it is not possible to produce exactly the same parts.
In particular, it is difficult to judge the material from appearance, so in many cases we select and propose a material that we think is appropriate based on the results of our research.
There are also cases where we propose a different shape from the perspective of cost and performance. In one previous case, the target was a cast iron part with a cast surface, but if we had produced it by casting as is, it would have taken a lot of time and cost. Therefore, during the investigation, we determined that there would be no problem with making a change, and proposed a machined cast iron part.
For production reasons, mass-produced products often use cast parts, which can be mass-produced once a mold is made, but when it comes to reproduction through reverse engineering, most are produced in very small quantities, such as one piece.For this reason, we propose remanufacturing cast parts with a different shape and material that has the same performance.
If you have any problems with your old machines, please contact us!
In addition to creating drawings for parts, we also accept consultations regarding machinery, such as old machines that have broken down. If you are having trouble with your old machinery, please feel free to contact us using the inquiry form below!
Difficult even with the physical object? Reverse Engineering of Gears
Introduction Gears are a common subject of reverse engineering requests due to their failure. While the basic mechanism of power transmission is the same, the shapes and combinations of gears vary greatly depending on their application. Even I, the author, discover something new every time I research gears…
Points to note when choosing grease
Introduction: Most machines with rotating parts, such as shafts, use bearings. Inside the bearings, grease is sealed to prevent wear and ensure smooth operation. Different types of grease are used depending on the application…
Reverse Engineering Techniques: Material Selection Based on Application (Part 3)
Introduction When using reverse engineering to repair old machines and restore parts, the material of the part can be a headache. If you make a new part using the same material as the damaged part, you can't easily distinguish it by measuring it with measuring tools or by looking at its color because the original part is still available...
