Every page contains a detailed description of the figures, graphics and basic mathematics used in The Book of Grinding.
Fundamentals:Superabrasives:Truing & Dressing:Cooling:Chatter:Other Subjects:10 hours
The Book of Grinding contains hundreds of scanning electron microscope (SEM) photos of grinding wheels, swarf, dressing tools and workpieces. During his courses, Dr. Badger often sees attendees experience an “Aha! moment” upon seeing an SEM photo, when a grinding concept can be visualized and suddenly makes sense.
The Book of Grinding is non-promotional. It contains no product endorsements.
The Book of Grinding has a strong emphasis on visual presentation and can be easily projected in Powerpoint-style, making is useful for internal company education to engineers and machine operators.
20 years and tens of thousands of dollars in development.
Many people who would like to attend the High Intensity Grinding Course have difficulty doing so due to production demands, scheduling conflicts, government travel restrictions, difficulties getting visas, etc. Yet they would like to get started in learning about grinding. Therefore, purchase of The Book of Grinding comes with one reserved spot in the course, which can be used at any course for up to three years after purchase.
The Book of Grinding is not inexpensive. However, most medium to large companies are spending millions of dollars a year on their grinding operations. In the right hands – smart, curious people with previous grinding experience – The Book of Grinding will more than pay for itself in terms of reduced cycle times, wheel consumption and scrap and quicker troubleshooting.
Dr. Badger is well known for taking complex grinding concepts and explaining them in a practical, down-to-earth, easy-to-understand way that can be used on the shop floor. This includes the material in The Book of Grinding.
Each page in The Book of Grinding contains a text description of these visuals. Complex mathematical formulas are simplified, charts and measurements are explained step by step, grinding, dressing and cooling phenomena are elucidated with SEM photos, and each section closes with key takeaways.
Machine operators, engineers, salespeople and management have found The Book of Grinding enormously helpful.
The Book of Grinding is delivered in electronic format on a USB drive. Users copy the contents to their computer and then use a dongle to open The Book. No software downloads are needed. The Book of Grinding cannot be printed.
Shipment of the book – folder, contents on USB, and dongle – is usually made within 48 hours of purchase. Shipping is paid by The Grinding Doc.
The Book of Grinding opens on any Windows computer or laptop. It cannot be opened on Macs.
The Book of Grinding has been created in standard 16:9 Powerpoint size, allowing it to be read easily on a computer or broadcast full-screen, one page at a time, using a projector. This is useful for internal company education and for salespeople wishing to explain grinding concepts to their customers.
The Book of Grinding is opened with a dongle, inserted into any USB port on the computer.
The Book of Grinding can be projected full-screen, Powerpoint-style, to larger audiences.
The Book of Grinding can be used in smaller, group discussions about issues facing the shop floor.
Grinding first started being studied scientifically in the 1950s. Since then, we have made great progress in understanding grinding from an engineering perspective – rather than as a black art. Unfortunately, much of this work is tied up in academic articles in the esoteric language of academese and complex mathematics.
The Book of Grinding takes hundreds of these articles and “translates” them into plain English, reprocessing the data into a graphics heavy (as opposed to text-heavy and math-heavy) format that is easy to understand by more practical, results-oriented engineers and machine operators.
The result is an invaluable educational resource that you will use and revisit for many years.
Dr. Badger has spent thousands of hours on the shop-floor of manufacturing facilities in over 30 countries – battling burn, burr and chatter, reducing cycle times, evaluating grinding wheels, quantifying grinding parameters and measuring wheel wear and grinding power.
These case studies are then processed and assembled into The Book of Grinding, with diagrams and figures explaining these complex concepts in plain English.
The Grinder’s Toolbox is a program for calculating grinding, dressing and cooling parameters. It is included with The Book of Grinding.
Includes The Grinder’s Toolbox.
Includes one place at the High Intensity Grinding Course, can be used at any time for up to three years after purchase.
