For some topics, there are brief activities. Intended Audience This course is intended for anyone needing to know the differences in Manufacturing functionality between NX 4 and NX 5. Prerequisites Basic understanding of the NX 4 Manufacturing application. ©UGS Corp., All Rights Reserved NX 4 – NX 5 CAM Transition 5 1 Lesson 1 General enhancements This lesson introduces general enhancements that apply broadly across the Manufacturing application. ©UGS Corp., All Rights Reserved NX 4 – NX 5 CAM Transition 1-1 General enhancements 1 Tool tips Menu bars, toolbars, and dialog boxes display tool tips. 1-2 NX 4 – NX 5 CAM Transition ©UGS Corp., All Rights Reserved mt11015-45_g NX 5 General enhancements 1 Machine time in the Operation Navigator The Operation Navigator displays estimated cutting times for operations and programs. The units are in hours, minutes, and seconds. If the feed rates are edited, the time is updated immediately. For turning operations with SFM or SMM feed rates, the time is calculated based on Max RPM. ©UGS Corp., All Rights Reserved NX 4 – NX 5 CAM Transition 1-3 General enhancements 1 Path length in the Operation Navigator The Operation Navigator displays estimated tool path cutting lengths for operations and programs. 1-4 NX 4 – NX 5 CAM Transition ©UGS Corp., All Rights Reserved mt11015-45_g NX 5 General enhancements 1 Simulation and verification (ISV) user interface The Simulation Control Panel dialog box has collapsible groups (1) that make it easy to display just the information you want to see. User preferences control which items to display in the ISV status area (2), so changing the machine tool driver (MTD) is not necessary. The new Stationary Tool (3) option makes it possible to keep the tool stationary as the tool path is simulated. The Synchronization Manager dialog box has new options: Show Channel Window turns the channel window on and off. IPW turns the In Process Workpiece display on and off. ©UGS Corp., All Rights Reserved NX 4 – NX 5 CAM Transition 1-5 1 Lesson 2 Milling 2 This lesson introduces enhancements that apply to Milling. ©UGS Corp., All Rights Reserved NX 4 – NX 5 CAM Transition 2-1 Milling Contour profile tilt angle Tilt Angle tilts the tool away from the wall (1) when Variable Axis Contour Profiling. This is useful when finishing regions between walls and floors. 2 2-2 NX 4 – NX 5 CAM Transition ©UGS Corp., All Rights Reserved mt11015-45_g NX 5 Milling Activity: Tilt the tool away from a wall ▸ Open tilt_angle. ▸ Choose Start®Manufacturing. 2 Replay a tool path with no tilt angle ▸ In the Program Order View of the Operation Navigator, double-click CONTOUR_PROFILE. NC_PROGRAM Unused Items PROGRAM CAVITY_MILL CONTOUR_PROFILE ▸ Click Replay . The side of the tool contacts the wall. Specify a tilt angle ▸ Click Cutting Parameters ©UGS Corp., All Rights Reserved . NX 4 – NX 5 CAM Transition 2-3 Milling ▸ Click the Tool Axis Control tab. ▸ Type 15 in the Tilt Angle box. ▸ Click OK. ▸ Click Generate 2 . The side of the tool clears the wall. 2-4 ▸ Click OK to complete the operation. ▸ Close the part. NX 4 – NX 5 CAM Transition ©UGS Corp., All Rights Reserved mt11015-45_g NX 5 Milling Optimized cut levels Optimized cut levels automatically reduces cut depth when encountering shallow regions. This results in tool paths that are spread uniformly on steep and shallow regions maintaining a consistent surface finish. Optimized cut levels is available for ZLEVEL_PROFILE_STEEP, ZLEVEL_PROFILE, and ZLEVEL_CORNER operations. ©UGS Corp., All Rights Reserved NX 4 – NX 5 CAM Transition 2-5 2 Milling Activity: Optimize cut levels on a core 2 ▸ Open optimized_cut _levels. ▸ Choose Start®Manufacturing. Replay constant cut level ▸ In the Program Order View of the Operation Navigator, double-click ZLEVEL_PROFILE. NC_PROGRAM Unused Items PROGRAM ZLEVEL_FOLLOW_CORE ZLEVEL_PROFILE ▸ Click Replay . The cut depth (measured along the ZM axis) is equal in steep (1) and shallow (2) regions. Optimize the cut level ▸ 2-6 Click Cut Levels NX 4 – NX 5 CAM Transition . ©UGS Corp., All Rights Reserved mt11015-45_g NX 5 Milling ▸ Select Optimized from the Cut Levels list. ▸ Click OK. ▸ Click Generate 2 . The cut depths have been reduced in the shallow regions, producing consistent scallops. ▸ Click OK to complete the operation. ▸ Close the part. ©UGS Corp., All Rights Reserved NX 4 – NX 5 CAM Transition 2-7 Milling Finish passes when roughing Planar Milling, Face Milling, and Cavity Milling allow you to create additional finish passes when roughing. The finish passes can be generated as non-cutcom, centerline-cutcom, and contact contour output. 2 1. Centerline tool path output 2. Contact Contour tool path output Additional finish passes do not apply to Standard Drive. 2-8 NX 4 – NX 5 CAM Transition ©UGS Corp., All Rights Reserved mt11015-45_g NX 5
