In 2020, like many others, the Covid-19 pandemic gave Eric more free time so he set about developing www.machiningdoctor.com and using his knowledge that can help all machinists from trainees to experienced professionals.
The main goal is to provide practical, quality technical information for professionals in the machining industry to assist in everyday tasks and to solve problems with machining calculators, raw materials, carbide grades, while there is also a machining glossary.
The heart of the website is the Speed and Feed calculator. It provides cutting data and carbide grade recommendations for milling, turning, drilling, parting, and grooving operations based on dozens of parameters like raw material, hardness, tool geometry, stability, grade selection method, and many more.
The results include cutting speed, feed, and additional data such as cycle time, power consumption, surface finish, etc. The calculator is constantly updated with new features to add functionality, improve accuracy, and enhance the user experience.
The general machining with metal removal rates, machining power, chip thinning, chip load and a basic calculations page.
A milling section has sections on chip thinning, chip loads and a basic calculations page.
The turning section has surface finish calculators tool to determine the best theoretical surface finish based on the insert's corner radius and feed rate along with a set of basic calculators to determine spindle speed, cutting speed, power, etc.
The machining doctor's database currently holds more than 700 raw materials. There are more extensive material databases on the web and it focuses on data relevant to the machining industry.
Each material datasheet contains: machinability rating, cutting speed recommendations, carbide grade recommendations, machining tips, chemical compositions and material standards conversion.
The information presented on the datasheets is based on a unique internal algorithm continuously enhanced to provide more accurate data.
The primary source of information on carbide grade is the cutting tools suppliers' catalogues. This situation presents two significant problems for the users in the machining industry.
You need to browse several catalogues to get the data, and the information is displayed differently by each supplier, making it hard to compare. To solve his issue, the Eric carefully studied the major supplier's catalogues, normalised the data according to a unified standard, and stored it in our database.
This database has online tools for carbide grades and includes a grade wizard, grade finder, grade converter, grade comparer, grade data sheets, alternative grades from other brands, application range and cutting speed recommendations.
The glossary contains about 100 machining terns and is constantly growing. When a glossary term appears anywhere across the website, it is highlighted with a "Wikipedia-like" tooltip that briefly explains the term. A click on the tooltip will open the full explanation.
