Cycle time is a major determinant of price per piece, but it may no longer be the main one. Seven characteristics specified by the customer may actually be the real cost drivers. Critical sales and estimating, if they are to be successful, recognize and challenge those assumptions that add cost, but not value, to our precision machined products.
Three primary criteria for selecting bar steels are 1) suitability for end use, 2) suitability for manufacturing process, 3) economical delivery of the requirements. Buyers may want to get the cheapest price per pound of steel purchased; Savvy buyers want to buy the steel that results in the lowest cost per finished part- assuring that costs are minimized for the total cost of production of their product.
Feed or Speed? High speeds can result in increased heat and toolwear. Higher feeds result in less horsepower needed per cubic inch of metal removal and less tool wear.
Manganese contributes to a steel’s strength, mechanical properties, hardenability, deoxidation, machinability, and reduces hot cracking (hot shortness) during hot rolling.
Nitrogen can be a hidden factor that affects your shops ability to ge tsurface finish, production, mechanical properties, and parts that may or may not crack during cold work.
Not every cause of poor finish can be addressed at the machine- The material chemistry is already established. These 5 tips will help you get Built Up Edge (BUE) under control and your surface finish back on track.
