By starting with precise, clean, and high resolution scan data, reverse engineering is made much simpler. Utilizing a 3D scanning equipment that will record the smallest and most intricate geometric details of your part is beneficial. This will significantly help in cutting down on processing time and any potential guesswork. Starting with “bad or poor” quality scan data is similar to attempting to follow cryptic instructions to reach a destination. Because of your navigational abilities, you might be able to make it, but it will undoubtedly take some time, work, and irritation. Our reverse engineering customers have stated that they have a precise and accurate foundation that reduces their CAD generation time thanks to the ATOS quick and simple physical to digital workflow and scan data quality.July 22, 2022 at 10:49 am in reply to: What can 3D printing do that CNC milling/drilling can not do? #2088
It is become simpler for manufacturers to employ additive manufacturing to build parts from a range of materials, including polymers like ABS, TPE, and PLA as well as carbon fiber composites, nylon, and polycarbonates. This is due to recent improvements in 3D printing technology. In the field of additive manufacturing, even pricy metals like Titanium, Stainless Steel, and Inconel are becoming more popular.
There is little doubt that the field of additive manufacturing will continue to advance and expand in the years to come, but will it completely replace subtractive manufacturing techniques like CNC machining? Without a doubt. As a new method termed “hybrid manufacturing” is swiftly gaining ground in the sector, precision CNC machining is actually probably more crucial to the additive manufacturing process than you may imagine.July 22, 2022 at 10:47 am in reply to: What are the advantages of dimensional inspection in casting? #2087
To ensure that the finished castings have the necessary overall dimensions, including machining allowances, dimensional inspection is done. To take measurements of the inside dimensions, it could occasionally be necessary to shatter a piece of the casting.
Some of the benefits of hiring an inspection service to ensure that your products are up to par are as follows:
Better quality products: Because these inspection services ensure that all products are manufactured to the highest quality standards, final consignments are less likely to contain any defective items.
Quantity calculated: The inspection team not only contacts suppliers, but also considers the needs of clients or consumers. They tour the fields to get feedback from the consumer marketplaces and customers, and then deliver the accurate demand data to the providers. The product is then manufactured only in the quantities required, saving the suppliers from overproduction or underproduction. Because the products are made in small quantities, they are more likely to be defect-free and perfect because they are made carefully and with great care.
Easy packaging: Another issue that the third-party inspection business manages is the product transportation process. The crew ensures that the packing material, size, and weight are all in compliance with the transit standards. This ensures that the product arrives at its destination without being broken, fractured, or leaking throughout the transportation process.May 11, 2022 at 3:05 am in reply to: What is supplier audit? Why conduct it when choosing your supplier? #1728
A thorough supplier audit can aid in the prevention and resolution of issues with supplier performance, quality, and delivery, resulting in increased customer satisfaction. A supplier audit gives insight into a vendor’s processes, verifying that they meet the manufacturer’s requirements and, ultimately, the customer’s requirements. We’ll go over the basics and benefits of supplier audits so you can see how important they are in your business. We’ll also present a helpful supplier audit checklist and explain the supplier audit/customer service relationship.
Once you’ve got this set up, the following pointers will assist you in balancing the system and reducing any errors:
Spindles are available in a variety of weight classifications, with some weighing less than 20 pounds and others weighing more than 100 pounds. Based on the predicted rotor/shaft weight, the program will provide the exact recommended trial and corrective weight.
Make sure that your spindle and software are both set to the same rotation direction. It’s critical that your program is set up to collect data in a clockwise direction if your device is set up for clockwise rotation. When balancing machine tools, this is a common mistake.
Tachometer Signal – Check to see if your tachometer is working. When tachometers are bumped or relocated, they frequently lose their signal. It’s also usual for the reflective tape to come loose during the balancing process, so keep an eye on it.
Tachometer and Accelerometer Alignment — Optimal tachometer and accelerometer configuration is essential for proper spindle balancing. Make sure your tachometer is on the same side as the accelerometers and in the same horizontal or vertical plane.
Misalignment and Tool Looseness — It is nearly impossible to balance a spindle that is misaligned or loose. Before attempting to balance a spindle, make sure you check for these two things.
April 11, 2022 at 7:48 am in reply to: What are the 7 qc tools used in quality management? #1601
- This reply was modified 1 year, 6 months ago by Jake Able.
The following is a list of the seven quality control tools:
The American Society for Quality (ASQ) has established seven quality control instruments that are widely used in the quality engineering community:
Diagram of Cause and Effect
Fishbone Diagram (also known as Cause and Effect Diagram) is a type of cause and effect diagram. A diagram can assist in determining the possible causes of an effect or problem. It assists in understanding the areas of opportunity through good brainstorming in addition to organizing thoughts into appropriate categories. Fishbone training enables you to pinpoint the problem’s root cause.
Chart of Controls
Control charts are used to investigate how processes have evolved over time. Furthermore, by comparing current data to previous control limits, one can determine if process variation is consistent (under control) or unpredictable (out of control) as a result of being affected by special causes of variation.
The Pareto Chart is based on the 80/20 rule, and it displays the major components that have the most impact on the problem at hand.
Sheet of Checks
A check sheet is a method for collecting and assessing data in an organized manner. It’s a versatile tool that may be used for a number of tasks.
A histogram is a graph that displays data and its frequency of distribution to assist users in identifying each unique value in a batch of data.
Diagram of Scatter
The scatter diagram depicts the relationship between two essential components, such as numerical data pairs, with one variable on each axis to show the link.
Stratification, often known as a flow chart or run chart, is a technique for separating data from several sources so that patterns, such as the path an object has traveled through a particular process, may be seen.
Using the seven quality control tools in the six sigma or quality management process allows for a systematic approach to identifying and understanding risk, assessing risk, controlling product quality fluctuations, and providing remedies to avoid future errors.
When should you use the 7 Quality Control Tools?
For improved quality management, 7 QC tools can be used throughout quality management, quality improvement procedures, six sigma implementation processes, or even the conventional PDCA cycle. Fishbone Diagram, also known as a cause and effect diagram, Pareto Chart, and Control Chart can be used in the first phase of measuring and identifying. Scatter Diagram, Histogram, and Checklist can be used in the next stages of assessment and analysis. The Control Chart can be used to maintain a high level of quality.April 11, 2022 at 7:43 am in reply to: What should I watch for when buying a used 5 axis VMC? #1600
Make sure you fully comprehend its geometry – that is, will the parts you care about fit when you add workholding and tooling? It’s typical to hear 5-axis machines described in ways that lead to misunderstandings about what size parts may be manufactured to fit. (For example, a UMC 1000 is accurately defined as 40×25, but the rotating table and trunnion prevent you from swinging a 40″ item, so it’d be more accurate to call it 25×25 – unless the part is elevated high enough, in which case it’ll be like 32×32….)April 11, 2022 at 7:42 am in reply to: What should I watch for when buying a used 5 axis VMC? #1599
You should inspect it as if it were a three-axis machine, then check the rotational precision. For example, inspect the site of a bore, then turn 180 and verify the location. A good check is to zero a surface, then rotate it 90 degrees and check the squareness. You should be able to check every 90 degrees if you have a flat rectangle to get a good notion of the accuracy. A simultaneous 5 axis cone type move also demonstrates accuracy, however most people use the 5 for 3+2.
The type of dimensional inspection device that is utilized for a given application is determined by several criteria, including:
The desired level of precision
Is it possible to touch the thing during the measurement process?
The object’s physical and surface qualities
The object’s transparency or opaqueness
You should know something about the term DNC (Direct Digital Control). This system makes it possible to load the data necessary for machining into the controller. That is, it is the means by which what is programmed in the CAM software, or via APT, is loaded into the programmed control machine.
It is basically a computer connected to a network in which there are one or more CNC machines. Previously, serial communications such as RS-232C or RS422 were used, but new communication technologies have improved these interfaces to Ethernet, and even wireless.
In some cases, this computer (which may be the same one used for the design), also stores the program or instructions that will be transmitted to the CNC machine. The reason is that some microcontrollers on these machines have too small enough memory to accommodate the entire machining program.
In the 80s, the hardware used for this was workstations from DEC, IBM, HP, Sun Microsystems, etc. Gradually, they became cheaper machines until today’s x86 PCs. Much cheaper minicomputers capable of running the vast amount of CAD/CAM software out there.
Recently, some graphic interfaces with touch screens and computers integrated into the CNC machines themselves make additional computer equipment unnecessary. Everything you need is on the machine itself or allows you to load the program using a simple USB stick.December 22, 2021 at 6:10 am in reply to: Will 3D printing replace CNC machining rapid prototyping? #1064
Benefits of Rapid Prototyping
Learn three benefits of using rapid prototyping in product development.
Significantly Reduce Time-To-Market
Rapid prototyping speeds up planning, design, prototyping, and feedback cycles to significantly reduce product lead times to market. In recent years, product development has become more liquid and shortened in the product lifecycle, so it is a major advantage to increase market competitiveness.
Streamline Engineering Effort and Costs
When prototyping is done by hand, skilled technicians need to spend a long time creating clay models (clay) and mockups (wood). Rapid prototyping, on the other hand, can mechanically create prototypes, significantly reducing engineering effort and costs.

There are 5 methods to clean CNC machined parts:
1. Ultrasonic cleaning – cleaning liquid to remove oil stains
2. Spray wash – Spray a cleaning fluid with a certain pressure and temperature onto the surface of the parts to remove oil stains
3. Scrub – Put the parts in a container filled with diesel, kerosene or other cleaning fluid, scrub with cotton yarn or brush.
4. Boil wash – Put the prepared solution and the parts into a cleaning bath of appropriate size welded with steel plates, heat it to 80~90℃ with an under-pool stove, and cook for 3~5min.
5. Vibration cleaning – The vibration of the cleaning machine is used to simulate the manual rinsing action and the chemical action of the cleaning liquid to remove oil stains.
