Introduction of Engineering Tolerance

Have you ever wondered how parts can fit so well together into a watch, or a smartphone? The key to a good assembly is in the engineering tolerance. Let's see the tolerance.

Tolerance is defining a range on a dimension or spec that can be allowed. Even using the most precise CNC machine, there will be slight deviations during production.

Creating the tolerance requires in depth knowledge of processing of how the parts inside a system is fitted together.

A very tight tolerance requires precise machines and experienced personnel, and the defect rate could go up, so the pricing will go up as well, and vice versa.

BILATERAL TOLERANCE

When the tolerannce allows both plus and minus range.

UNILATERAL TOLERANCE

When the tolerance only allows either plus or minus number. Aside from geometric tolerance, there are also tolerance for temperature, hardness, pressure... etc.

Advantages of Rapid Prototyping

One of the complex challenges that product designers face, is how to give clients a quick understanding of what the product looks like and how it functions.

Needless to say, rapid prototyping is no doubt a strategic capability. Attempting to be the first to launch a new product gives your company a competitive advantage as it offers a fast and accurate way to know more about the potential of the product.

Rapid prototyping enables your clients or product users to look at and touch the design before they want their orders to be brought in production.

Rapid prototyping is a modern-day technology that serves to demonstrate the precision level of computer modelling, such as CAD, Pro/E ...etc to help us move faster to meet our client's requirements.

Some significant benefits of rapid prototyping include:

1. Basic understanding of design concepts
2. Rapid prototyping in accordance with specific designs
3. Finding out possible design flaws before mass production
4. Cost-effective and time-saving

The application of rapid prototyping in product development is inevitable and will be in widespread use in the industrial filed. In a highly competitive market, this tool takes you a step closer to success in customer relationships.

Grinding

There are many forms of grinding, but the four major industrial grinding processes are：

•Cylindrical grinding

A cylindrical grinder is used for shaping the outside of a workpiece. These machines accept workpieces in a variety of shapes as long as they can be rotated through a central axis.

In a cylindrical grinder, both the workpiece and grinding wheel are simultaneously rotated. Outside diameter grinders, internal diameter grinders, and centerless grinders are all types of cylindrical grinders.

•Internal grinding

Internal grinding is used to grind the internal diameter of the workpiece. Tapered holes can be ground with the use of internal grinders that can swivel on the horizontal.

•Centerless grinding

Centerless grinding is when the workpiece is supported by a blade instead of by centers or chucks. Two wheels are used. The larger one is used to grind the surface of the workpiece and the smaller wheel is used to regulate the axial movement of the workpiece.

Types of centerless grinding include through-feed grinding, in-feed/plunge grinding, and internal centerless grinding.

•Surface grinding

Surface grinding uses a rotating abrasive wheel to remove material, creating a flat surface. The tolerances that are normally achieved with grinding are ±2×10−4 inches (5.1 μm) for grinding a flat material and ±3×10−4 inches (7.6 μm) for a parallel surface. Please get a quote from Harry Yen hyen@unisontek.com.tw Our team will reply to you with feedback in two working days.

Reading ANSI Tables

How to read the “ANSI tables”, aka “AQL tables”

Source: Mil-Std 105E, replaced by commercial standards:

ISO2859, ANSI/ASQ Z1.4-2003, NF06-022, BS 6001, DIN 40080.

Random Sampling

¤  100% inspection can consume a lot of time, or destructive.

¤  How many should you check?

¤  Follow statistics rather than a fixed percentage

¤  Widely used settings:

¤  Normal severity

¤  Level II

Acceptance Quality Limit (AQL)

¤  How do you decide if the batch is accepted or rejected?

¤  The buyer and the supplier should agree on AQLs.

¤  Widely used settings for consumer goods in China:

¤  0% for critical defects (totally unacceptable: a user might get harmed, or regulations are not respected).

¤  2.5% for major defects (these products would usually not be considered acceptable by the end user).

¤  4.0% for minor defects (there is some departure from specifications, but most users would not mind it).

Example

¤  Order size: 40,000 pcs of memory sticks, to be made in 1 batch by the supplier.

¤  Single sampling plan.

¤  Normal severity, level II.

¤  AQLs: critical 0, major 1.5%, minor 4.0%.

Step 1: The Code Letter

Step 2: Sample Size and AQLs

This Special Case

¤  The ISO2859-1 standard says:

¤  If this procedure leads to different sample sizes for different classes of nonconformities or nonconforming items, the sample size code letter corresponding to the largest sample size derived may be used for all classes of nonconformities or nonconforming items, when designated or approved by the responsible authority.

Conclusion (for Single Plan)

¤  Your code letter is “N”, so you will have to draw 500 pcs randomly from the total lot size.

¤  Here are the limits: the products are accepted if NO critical defects, and NO MORE than 14 major defects, and NO MORE than 21 minor defects are found.

¤  Examples: 

¤  If you find 0 critical defect, 17 major defects and 12 minor defects, the products are rejected. 

¤  If you find 0 critical defect, 10 major defects and 21 minor defects, the products are accepted.

Same Example, Double Plan

¤  For simplicity, let’s only look at major defects.

¤  Code letter is unchanged.

Conclusion (for Double Plan)

¤  1st step: draw 315 samples and check them.

¤  If you find 7 defects or less: the lot is accepted.

¤  If you find 11 defects or more: the lot is rejected.

¤  If you find between 8 and 10 defects: go for 2nd step.

¤  2nd step: draw another 315 samples and check them.

¤  If you find 18 defects or less in total: the lot is accepted.

¤  If you find 19 defects or more in total: the lot is rejected.

Metal Parts Manufacturer

As an OEM/custom machined metal parts manufacturer, Unison Tek does not just solve problems for our customers, we go beyond that - we anticipate the issues that our customers might face along the way, and tackle with them before they can even surface.

With decades of experiences in this field, we’ve learned that burr migh get in the way of affecting the quality of the finished products.

The case study below shows one way of effectively deburring/ deflashing the parts using liquid nitrogen.

Liquid nitrogen frozen deflashing machine 

Liquid nitrogen frozen deflashing machine proves to be working well when deflashing the parts, especially for plastic material. It’s a process using liquid nitrogen to freeze processing objects (temperature to be 180 degrees Celsius below zero).

By doing so, the objects will become hard and brittle. Then, we can use plastic sanding material for blasting, in order to reach complete deflashing.

The perks of applying this procedure are numerous. It’s cost-efficient, labour-saving, and unlike traditional deflashing process, it generates productivity and decrease the chance of defect rate.

It’s suitable to put to use for plastic material, rubber, die cast, aluminum alloy, to name just a few.

The sanding material is made from plastic, which can further avoid damaging the surface.

This case is one of many successful examples that we achieved for our customers. And this is what makes this line of business so valuable – we are constantly learning and advancing, along with our customers.

Introduction to Grinding 

Grinding is an abrasive machining process that uses a grinding wheel or grinder as the cutting tool. Grinding is a subset of cutting, as grinding is a true metal-cutting process. It can produce very fine finishes and very accurate dimensions.

Grinding is a subset of cutting, as grinding is a true metal-cutting process.

Each grain of abrasive functions as a microscopic single-point cutting edge (although of high negative rake angle), and shears a tiny chip that is analogous to what would conventionally be called a "cut" chip (turning, milling, drilling, tapping, etc.).

Deep hole machining

Deep hole machining means to make holes ten times deeper than hole diameter. There are a variety of different CNC or machine set-ups to do this. The most common method is rotating the work pieces on turning method. Rotating tool is also possible.

The gun drill, originally developed for building gun barrels, is a machine tool that is specifically used for such operations.

Methods and Tools

Whichever method and tool, the usual standards of drilling are the same. The quality depend upon correct choice of tool, rotate speeds and feeding method.

Crucially, the cooling, chip breaking, and removing the chips from a long tool are all deeply important. They are the difficulty as well as essential know-how, involved in producing a good deep hole.
