| How to evaluate your cutting tool |
|
With the implementation of new cutting tool technologies, companies can focus on time cost reduction, shortening leadtimes and in many instances reaching the break even point of their cutting tool investment within hours. How do we measure the progress of a tool we’re building? How do we measure success in business or our career? One way or another, the answer to these question always involves some measure of time (i.e., how long to build a tool, how much money does the company make per year, how much money do you make per hour). Of all things involved in manufacturing, time is the one factor that can have the greatest influence on increasing profits and upgrading the capabilities of our companies. With regard to moldmaking technologies (e.g., machine tools, CAD/CAM, cutting tools, materials, etc.), the technology you are using today is already outdated. The ideas for the next generation of machine tools, cutting tools, etc., have already gone through research and development, and are in production. They will eventually impact the way you, your company, and the die and mold industry approach manufacturing. The technology is ever changing, rapidly moving, and comes at a price, but it’s measurable, and when that measure can be justified, it’s time to make the investment. With that said, the remainder of this article will focus on cutting tool technologies and how these tools can reduce the overall manufacturing costs. When considering all of the technologies being put to use on a daily basis for the machining of dies and molds, the cutting tool is one of the least expensive, but most highly scrutinized purchases that a company makes. As employees, we need to learn the basics of justifying an investment to an owner or someone responsible for purchasing. As owners, we need to look at the entire picture—there’s more to determining the value of a cutting tool (or any technology) than simply considering its price, and that the right question is not, “What is the price”, it’s how much can I make by implementing this technology? Time Costs The improvement was due to the increased metal removal rates (circled area) made capable by the introduction of new cutting tool technology. The new technology was introduced and implemented in approximately half a work day. Tool Costs Much of these advancements are made possible by utilizing the latest pressing techniques (pressing of the carbide insert), enabling the creation of stronger tools and inserts that have more cutting edges, making better use of the carbide. Some examples of this incorporate tangentially mounted inserts with more cutting edges per insert .
