Point-to-Point Processing

The NC point-to-point options allow you to quickly process patterns of holes, slots, and other common features. Predefined system cycles or user-defined macros can be applied at each location selected. Hole processing in plates, jigs and fixtures, and other tooling is performed efficiently using the features of the point-to-point functions.

AUTOMATIC PROCESSING FEATURES LISTS

Features: The system allows you to select a set of points that are used to generate tool motion positioning output. For instance, a pattern of holes to be drilled, chamfered and tapped can be represented by selecting individual hole centers or be predefining arrays and groups. When a pattern is selected, the required operations are performed at each position in the pattern. In this way, hundreds of position locations can be selected easily for subsequent stages of point-to-point processing.

Benefits: Costly human errors are reduced because lists of point-to-point positions are processed automatically.

OPTIMIZED PROCESSING

Features: Once position locations are selected, the order of processing can be optimized to reduce machining time. You can specify the starting location for point location processing and use either vertical or horizontal positioning priority. The system generates the optimum order for machining instructions, according to the priority you set.

Benefits: Machining time in the shop becomes more efficient because linear free motion between point-to-point locations is reduced. The cutting tool spends more time making chips and less time moving through the air. This improved efficiency results in significant savings of time and money.

TOOL COLLISION AVOIDANCE

Features: During point-to-point processing, the NC system checks for potential Z-depth collisions. If the next Z-depth motion could result in a tool collision with the part, the tool is moved to a clearance plane before it is positioned over the next point.

Benefits: Tool and workpiece collisions are avoided, thereby reducing scrap, rework and expensive machine repair.

AUTOMATIC MACHINING CYCLES

Features: You can choose from several system-supplied machining cycles, including drill, chamfer, deep drill, chip break, tap and bore. You select the type of cycle required and enter parameters to control the tool motion generated at each point location. You can choose "canned" cycle output format to evoke machine tool internal functions or "expanded" output to simulate high-level machine tool internal functions if your machine lacks those capabilities.

Benefits: Efficient use of machine tool internal cycle commands reduces tape image length and reduces overall processing times. The flexibility of "canned" and "expanded" cycle functions provides a single means to program new and old machine tools.

USER-DEFINED CYCLES

Features: You may need to process each point-to-point feature in a predetermined way that is not supported with system-supplied cycles. Using NC macros, you can define and use your own special cycles and apply to each point position. Essentially, the combination of functions that can be applied to point-to-point operations is limitless.

Benefits: Special milling, facing or other requirements are accomplished easily. You have the flexibility to establish and adhere to processing standards that are maintained throughout your manufacturing organization.
