With NC Prismatic & Mill-Turn Machine Programmer (NTP), users can program milling and turning machines to produce 3D parts that require advanced 2.5-axis milling and turning operations. They can program complex multi-tasking mill-turn machines with synchronization and part transfer capabilities.
The 3D environment immerses NC Programmers in a realistic virtual workplace as they create, optimize, and validate NC programs for 2.5x milling and turning processes. NTP provides a full set of features for workpiece setup, cutter tool assembly, and toolpath simulation that include material removal, machine-tool simulation and NC code generation. NC programmers can capture and leverage enterprise intellectual property and collaborate with other stakeholders as they develop, validate, and optimize NC programs. NTP makes it easy to access current information about machining resources, programs, and machine tool setup.
Accelerate NC programming.
NTP users can quickly author and edit NC programs. Intuitive graphic dialog boxes, traffic light indicators for undefined machining parameters, and help icons for each parameter operation make the process highly efficient. Tool changes and machine rotations are automatically generated and can be visualized in the machining operation definition panel. Copy-and-paste functions help organize programs in the specification tree.
Maximize machine tool utilization.
NTP’s wide range of operations and strategies helps programmers create toolpath programs that minimize non-value-added motion. Optimized NC programs, including high-speed machining features, reduce overall machining cycle time. NTP takes in-process parts into account to generate collision-free tool paths.
Mitigate risk to production.
NTP’s 3D environment enables programmers to create optimized NC programs in the manufacturing context: NC machine, cutter, tool assemblies, NC accessories and other elements. This provides a better understanding of the machining cell and ensures that the tool path and machining strategy take the tool’s physical environment into account. It reduces the risk of unexpected issues and production delays.
Leverage intellectual property.
NTP improves automation and standardization of NC tool path programs. Users can define and store machining processes as dedicated templates, and store them in catalogs for reuse. Company intellectual property is capitalized and re-used to make programming more efficient. The gains in productivity and machining-work standardization are significant.
A single design-to-machining solution to understand engineering changes.
Based on the 3DEXPERIENCE® platform, NTP provides an unrivaled level of associativity between product engineering, manufacturing processes, and resources. Companies can manage concurrent engineering and manufacturing flows better and shorten the design-to-manufacturing cycle. NTP offers the best available support of design changes or design variants and the rapid creation of programs for families of parts. Native implementation links connect machining programs to engineering and manufacturing data. These links can be used to see which machining programs are impacted by engineering or manufacturing changes. Like a new cutter, for example, and to see whether machining data is up to date with respect to engineering changes.
NTP was repackaged in 2021x with the following 2020x & 2021x roles:
Manage and program machining resources with powerful multi-tasking mill-turn capabilities
Manage CNC machines, accessories, tools and tool assemblies in 3D. These resources can be retrieved through standard search capabilities using relevant machining attributes and instantiated in a machining cell. Users can clearly see the impact of changes on the definition of objects such as parts or cutting tools across all NC processes and programs. NTP supports default or customized representations of the cutter and tool assemblies that used for verification, simulation with material removal, and collision checking. Programmers can author NC programs for complex mill-turn machines with multiple spindles and turrets using synchronization features, balance turning, and part-transfer capabilities. Through an immersive, intuitive interface, users can synchronize operations and passes within an operation and define part-transfer activities.
Automatic association of prismatic machining features with part design
Automatically recognizes the prismatic machining features of the product design, significantly reducing toolpath programming time. A manufacturing view of the design part is generated, with all the drilling and milling features that are to be machined. Through this embedded feature-recognition technology, NTP enables toolpath programming for geometrical-machined, feature-creation design parts—even those with no design feature specifications.
Best-in-class machining strategies for efficient programming of turning and mill-turn machines
Offers a full set of high-end turning operations such as roughing, finishing, groove turning, groove finishing, and thread turning for accurate toolpath definition. NC Programmers can also author turning operations to address B- and C-axis interpolations of mill-turn machines.
Creation and optimization of 2.5-axis milling, drilling and probing operations
NTP offers a broad range of machining operations for toolpath definition, including pocketing, facing, and contouring. These operations can be defined as multi-level and multi-pass. At the user’s request, the tool path can be optimized for high-speed machining. Point-to-point machining is available, as well as a full set of axial operations from standard drilling to complex boring and chamfering. Several dedicated strategies for hard material are included such as trochoidal milling, concentric milling and spiral morphing. This concentric strategy controls the radial engagement to maximize the efficiency on the machine while protecting the cutter. NTP offers unique functionalities for creating and verifying milling, drilling, and probing operations. Probing operations are very flexible and can be customized with associated user parameters. NTP extends the 2.5 axis capabilities by offering best-in-class 4-axis pocketing that includes a variety of strategies, island management, and user-defined lead angle on the tool axis for better cutting conditions. This operation also supports non-cylindrical and non-conical surfaces and revolution surfaces going beyond the 180 degrees.
Quick toolpath verification and editing
Toolpath replay allows the generation and verification of individual operations or of the complete program. Users can visualize the in-process part and analyze remaining material. Alternative machining strategies can be tested to obtain collision-free trajectories. The tool path can be replicated, mirrored, translated and locally edited. The Compare Part and Remaining Stock command display only the differences. NTP Improves toolpath verification by pinpointing a lack of material or material in excess.
Advanced simulation capability
NTP has powerful simulation capabilities for toolpath validation. This simulation functionality brings one of the most advanced machine simulation modules to the market to identify potential issues earlier in the process. NTP has the capability to compute volume of gouge in the workpiece, making it easier for users to prioritize and process gouges in machining programs. Near misses (at user defined safety distance) are identified, and multiple tool change locations are supported for a more accurate simulation of the machine motions. The simulation context, saved in the 3DEXPERIENCE platform, allows the user to organize the review in the most convenient way. This ensures traceability of the validation task. It allows users to program, optimize and validate machining in the most efficient way. It lets NC Programmers identify toolpath errors earlier in the process and shortens programming time.
High levels of automation and standardization
Machining processes can be defined as dedicated templates and stored in a catalog for re-use. The stored template can be retrieved and applied to the design features of the part geometry. The company’s intellectual property is capitalized and re-used to make programming more efficient. NC objects and attributes are handled as Knowledgeware objects in order to increase the level of automation and standardization in NC program creation.
Seamless NC data generation
Offers seamless generation of APT source and NC Code ISO format through the integrated post-processor execution engine, the library of standard post-processor syntax mapping tables and Post Processor samples. The output formats can easily be customized. Additional files generated by the post-processor are also automatically saved in the same container in the 3DEXPERIENCE® platform, thus ensuring that all relevant outputs for a given part are available at the same location and are up to date. The manufacturing program’s key information can be exported as documentation for reference on the shop floor.
Wire EDM Machining
Simulate, validate, and program wire Electrical Discharge Machining (EDM) processes. Compute the wire EDM path and program the synchronization of each end of the wire to the part contours. Implement 2 and 4 axes programming capabilities with dedicated wire EDM strategies, and visualize & validate the program strategy. Produce the machine code for use in the real machine. As with all DELMIA Machining applications, users can save and re-use best practices by creating the wire EDM paths, storing these in a template, and then re-using the same strategy on other parts to be machined.
