Knowledge and internal processes are based on proven technologies that ensure the part does what it is intended to do and performs beyond expectations. S tandardized tooling is embedded in our daily produc- tion routines. Te price of "of the shelf " holders or TiN coated carbide inserts are quickly calculated by digging through a few price lists. Obtaining pricing for customized tooling requires more time and efort, but the long-term cost savings could be worth more than is obvious. Creating Custom Tooling In order to produce an application-specifc tool, the tooling manufacturer needs to review a shop's application and deter- mine if a solution can be provided. Tis means the shop has to compile information such as material used, drawings and machine data, and then explain how it plans to produce the component. Te process can eat into the shop's time, especially if the application was submitted to multiple tooling vendors for review. Te tool manufacturer reviews this information and asks questions until they understand the appli- cation. It may take a few minutes or a few days to digest the information and determine if a solution can be provided. Te manufacturer has most likely seen other similar applications and often can provide a quote fairly quickly based on their previous experience. Once the shop has made a decision to move forward and place an order, it's safe to assume that tool approval drawings will be provided by the tool manufacturer. Te approval drawings may be prepared in a day or a few weeks. It really depends on the complexity of the tool and ultimately will require the shop's stamp of approval before the custom solution can be produced. Te tooling manufacturer schedules the new job for production once drawings are approved. In some cases, the tool selection and programming occurred during the approval drawing stage, where the component was designed. So far, quite a bit of time is tied up in an item that only exists in a CAD system. Te raw material is still unchanged, and the cycle start button has yet to be pressed. Not a single chip has been cut or edge ground. Te whole process may seem costly to some, but tool manufacturers do this every day. However, knowledge, experience and internal processes are based on proven technologies that ensure the end product does exactly what it is intended to do and performs at a level beyond expectations. Standardized Tools are Based on Lengthy R&D While custom tooling is a process, standardized tooling is of the shelf. However, mass produced tools and the knowledge behind them did not happen overnight, and most so-called standard tools started their lives as a custom solution to a challenge or need. Every standardized tool for a given machine tool application is based on years of trial and error. Probably the biggest beneft of standard tooling is time savings. Once a tool selection is made, delivery can be fast. Tools that have survived these tests are now readily avail- able from distributors who keep stock of the most common tools for a shop's machining needs. If a shelf is wiped out by a large order, the tool manufacturer can usually prepare a drop shipment the same day. Such proven tool technologies bring the beneft of engineering standards, as far as selection is concerned. Open any machinist's reference manual, and it will contain charts listing predetermined dimensions and formulas in an easy-to-comprehend format. While the selection process may require a basic under- standing of algebra, trigonometry, machine limitations and :: There is a need for application specifc, custom tools.
