hyperMILL has enhanced the implementation of technology macros from only containing static processing steps to include intelligent macros. The intelligent macro contains information for many programming situations and only selects those required based on the current scenario.
In CAM programming, a technology macro is understood as a specific sequence of machining steps with tool and technology data for characteristic geometries. In practice, macros enable "programming with a click of the mouse." For each geometry feature, the software independently searches for the right macro in a technology database in which all of the macros are stored. This enables the automatic creation of complete machining steps. The database is populated by saving machining processes (one step or more) that have been programmed with traditional direct techniques. No special programming skills are required to prepare the technology macro database.
hyperMILL can now store the various job steps required to fully process a part model. Rules and logical conditions can be defined for each individual job step. hyperMILL automatically adjusts job steps on the basis of these rules and in reference to the geometry information.
For example, a hole with a diameter of 8mm that may have various depths of 6mm, 14mm, 30mm and 120mm. Depending on how deep the hole is, different machining approaches are required. These can now be completely stored in one single macro. With a simple "if-then rule," the relevant part of the macro is put into action.
When drilling, it had previously been sufficient to select a macro based on a reference number and checking the required tool length. Now, in hyperMILL version 2013.2, the user can also run a search to find the hole diameter. For example, if a drill macro is applied to a hole with a diameter of 4, then the macro will look for a drilling tool 4 in the database. If the same macro is applied to a hole with a diameter of 6, a drilling tool 6 will be retrieved automatically. So, this is an automatic tool search, one that now also takes into account the hole diameter, meaning more convenience for the user.

Use of computers to control machining and manufacturing processes.
- drilling tool ( drill or drill bit)
drilling tool ( drill or drill bit)
End-cutting tool for drilling. Tool has shank, body and angled face with cutting edges that drill the hole. Drills range in size from “microdrills” a few thousandths of an inch in diameter up to spade drills, which may cut holes several inches in diameter. Drills may have tapered shanks with a driving tang and fit directly into a spindle or adapter, or they may have straight shanks and be chuck-mounted. The rake angle varies with the material drilled. Styles include twist drills, straight-flute drills, half-round and flat drills, oil-hole drills, indexable drills and specials.
