Polar Stroller

Cool Machining Projects - Skis of Strollers or Bike Trailers

I’m very fortunate that our CNC service can help Mr. Glenn Patterson and Mrs. Kelly Patterson to finish a fantastic case together, from design, prototyping, to successful CNC service mass production.


It’s start from a warmly strong of Mr. Glenn Patterson and Mrs. Kelly Patterson. It all began after the birth of their first son, who only napped whilst on the go in his stroller. They love the great outdoors and the physical and mental health benefits that mother nature has to offer. Their passion for staying active with their little ones, whilst in the warmth, comfort and safety of their stroller, is what first drove them to design his first set of stroller skis.

They wanted their baby to have a first class ride, gliding over the rutted, snow packed pathways and floating over the snow. Bringing joy and happiness to exploring this winter wonderland as a family. As avid winter sports fans with engineering, manufacturing and children’s health care specialist expertise, they began designing and combining.
As parents they knew how important it was to have a quick and easy product to attach to the existing wheel, to avoid those meltdown moments when the stroller is not moving. No tools needed to fit, adjust or remove the skis. Strong and durable to carry their child safely and to look good on our stroller. Based in Alberta, at the foothills of the Rocky Mountains, they had the perfect testing grounds.

Design & technology for Cool Machining Projects

application of rapid prototyping in manufacturing industry
After having an idea, they start to design, and make the drafts. At this stage, I’m lucky to have an opportunity to take part in this project. They send me the drafts to approve the production technology for producing. We have a long discussion until both the drawings and technology are approved by both of us.

CNC service is recommended, and approved by us finally. There are 4 points why we choose CNC service.


CNC service will avoid the designer to change the most reasonable design, due to technology limited. CNC service can use the most common solid bar, and use machining or milling technology to reach different shapes. It will avoid wasting time to develop moulds, searching different shapes raw material, and find the different technology machines (casing machines, forging machines, stamping machines, etc)


After producing by CNC service, you will not worry about the shape, dimensions, tolerances, positions, parallelism, straightness, homogeneity, flatness, etc. All of them are according to drawings and what you want. CNC service is also good for assembling, because good dimensions, tolerances, positions, parallelism, straightness, homogeneity, flatness, etc, will help the workers to assemble the parts together easily and efficiently. In other words, CNC service is saving the money for you.


Solid bar has a strong molecular structure after forming. It is much better than casting, MIM, stamping or forging. It is also better for heat treatment and surface finish, such as electroplate, anodizing, black oxide, chrome plating, etc. As the skis are for Skis for Strollers & Bike Trailers, safety is the most important. CNC service based on solid bar will take this project strongly, safety and no complaint.


CNC service will take good blade trace roughness for all the surfaces, no matter if they are surface finished or not. The market welcome the beautiful appearance products launched. Beautiful appearance will also help the products to be a modern innovative development.

Cool CNC Machining Fundamental Process in This Project

(i) Productive Process

Types of equipment productive processes are the process for making the products from raw material (unfinished blanks). Types of equipment productive process include raw material transit and storage, CNC service machining production preparing, unfinished blank making, precision parts’ CNC service machining and heat treatment, precision parts’ assembling, test, painting, and package, etc.

Technics process

In the productive process, there is a technical process.
Technics process is the process to change the workpiece’s shape, dimensions, positions, and character, etc, and make the workpiece to finished precision parts or unfinished blanks.
Technics process is a key part of the productive process.
Technics process includes casting, forging, stamping, welding, CNC service machining, assembling, etc.
Types of equipment production technics process include precision parts’ equipment production technics process and types of equipment assembling technics process.
Others are auxiliary processes, for example, transit, storage, power supply, equipment repair, etc.

Technics process

Technics process also consists of one or several tactic processes, one process consists of several steps.
A process is an elementary unit for types of equipment production technics process.
Process definition is the technics process, that one worker (several workers) finish production continuously on one machine (or one position) for the same workpiece (or several workpieces).
The main characteristic of the process is that it doesn’t change the workpiece, types of equipment, or operator, and continuously.
The step is based on the same CNC service machining surface, the same CNC lathe machining tools and the same volume of feed
The Feed is a working process, which is a step for production finish on the workpiece’s surface by tools.

Technics flow

When making the types of equipment’s technics process, you have to make sure how many steps the workpiece needs and the sequence.
Technics flow is a simple process of key processes and sequences.
Technics flow is very important for making technics process,
Its function is to select the correct processing method for each surface, make sure the sequence of each surface, and the number of processes.

(ii) Productive Category

Productive Categories are usually divided into three categories,
a. Single workpiece production: manufacture different structures’ and dimensions’ workpiece separately, and seldom repeat.
b. Batch production: manufacture the same structure and dimensions’ workpiece among one year, there is some repeatability in the manufacturing process.
c. Mass production: the quantity is huge, manufacture the same process in the same place.

(iii) Process planning

lanning principle

1. Every technological procedure is planned to make sure
the quality of precision parts (types of equipment assembling),
And reaches all the specifications as the drawing requests.

2. The technological procedure should have high productivity,
The products made by technological procedures should be launched as fast as possible.

3. Try our best to decrease the production cost

The instruction for benchmark of Cool Machining in This Project

medical cnc machining

(i) Definition

Precision part consists of several surfaces,
When analyzing the relative relation of the surfaces, you must confirm a benchmark.
Benchmark is a dot, line, and surface to confirm the part’s dot, line, and surface.
According to the different functions of the benchmarks, there two categories,
One is the design benchmark, the other is the technical benchmark.

(ii) Category

1. Design benchmark: the benchmark to confirm the dots, lines, and surfaces on the drawings
2. Technics benchmark: the benchmark for production and assembling.
3. Assembling benchmark: the benchmark for confirming the parts’ position in the products when assembling
4. Measure benchmark: the benchmark for inspecting the sizes and position
5. Locate benchmark: the benchmark for CNC lathe machining.

CNC service machining Processing Cushion

Cool Machining Projects

ecm machining technology


When the blank is made to finish the product, you will be machining out the metal layer, The total of the metal layer is called the total processing cushion. The metal layer of every process is called process cushion. As to the circle and hole, the processing cushion is on the diameter, called symmetry cushion.


The reason, why the workpiece has the processing cushion, is to CNC service machining out the tolerance or defect on the workpiece from the last process, for example,
The cold layer of casting parts, bubble hole of casting parts, the sand layer of casting parts.
Oxide skin of forging parts, surface crack of forging parts, decarburized layer of forging parts.
The surface roughness of CNC service machining, etc.


The processing cushion can increase the precision and roughness of workpieces.
The volume of processing cushion will affect the product quality and production efficiency.
If the processing cushion is too big, it will increase the CNC lathe machining sum of labor,
Decrease the production efficiency, increase the loss for raw material, tools and power,
And increase the production cost.
If the processing cushion is too small, the tolerances and defects from the last process cannot be removed, the tolerances for loading and unloading cannot be removed too.
The principle is selecting the smallest processing cushion based on high quality.
