These 2D and 3D high speed dynamic milling toolpaths utilize the entire flute length of their cutting tools to achieve great efficiency in milling. They are designed to maxi- mize material removal while minimizing tool wear. Additional benefits you gain by using high speed dynamic milling toolpaths include:  Tool burial avoidance  Minimum heat buildup  Better chip evacuation  Extended tool life This tutorial introduces you to Mastercam's intelligent, application-specific, 2D and 3D high-speed dynamic milling toolpaths. Tutorial Goals  Learn the benefits and uses of the Dynamic toolpath types  Create basic Dynamic toolpaths  Create stock models  Learn to use other Mastercam toolpath utilities 6 MASTERCAM 2017 FOR SOLIDWORKS / Introduction Estimated time to complete this tutorial: 5 hours General Tutorial Requirements All Mastercam for SOLIDWORKS tutorials have the following general requirements:  You must be comfortable using the Windows® operating system.  You must have a seat of SOLIDWORKS® 2015 or higher to complete this tutorial.  Each lesson in the tutorial builds on the mastery of preceding lesson’s skills. We recommend that you complete them in order.  Additional files may accompany a tutorial. Unless the tutorial provides specific instructions on where to place these files, store them in a folder that can be accessed from the Mastercam for SOLIDWORKS workstation, either with the tutorial or in any location that you prefer.  You will need an internet connection to view videos that are referenced in the tutorials. All videos can be found on our YouTube channel: www.youtube.com/user/MastercamTechDocs. Dynamic Toolpaths The following toolpaths use Dynamic Motion technology:  Dynamic Contour  Face  Dynamic Mill  Peel Mill  Dynamic OptiRough Each toolpath has various benefits that make them unique from each other and their standard counterparts. Dynamic Contour The Dynamic Contour toolpath creates a familiar contour operation using dynamic motion and specialized options found only in dynamic toolpaths. The dynamic motion MASTERCAM 2017 FOR SOLIDWORKS TUTORIAL (MILL) DYNAMIC TOOLPATHS 7 prevents tool burial and binding in small radii corners. Additionally, you can specify how Mastercam machines any material left on the walls. Face The Face toolpath, when the Style is set to Dynamic, quickly cleans stock from the top of a part and creates an even surface for future operations. You can base the toolpath on either chained geometry or on the current stock model. Dynamic Mill The Dynamic Mill toolpath machines pockets, leftover material, standing bosses, or cores. By setting the Machining region strategy to Stay inside or From outside, you can create a pocket toolpath that utilizes dynamic motion or a facing operation that has island avoidance capabilities. By selecting the Stay inside strategy, Dynamic Mill becomes a pocket toolpath that utilizes dynamic motion. You select a boundary, areas to avoid, and set tooling, param- MASTERCAM 2017 FOR SOLIDWORKS TUTORIAL (MILL) 8 MASTERCAM 2017 FOR SOLIDWORKS / Introduction eters, entry method, and linking values to generate the toolpath. Material is removed from the inside to the outside in a highly efficient manner. By selecting the From outside strategy, Dynamic Mill becomes a facing operation that has island avoidance capabilities. This movement creates a toolpath that is allowed to move outside the selected material and removes from the outside to the inside. By enabling Rest Material on the Stock page, the Dynamic Mill toolpath removes material left by previous operations using dynamic motion. The Dynamic Mill opera- tion calculates how much material to remove based on previous operations or MASTERCAM 2017 FOR SOLIDWORKS TUTORIAL (MILL) DYNAMIC TOOLPATHS 9 previous roughing tools. Only unmachined areas are processed for a Dynamic Mill operation. Peel Mill Peel Mill, with the Cutting strategy set to Dynamic Peel, allows for efficient milling between selected chains. It uses a dynamic style of motion with accelerated back feed moves when the tool is not engaged in material. For a single chain, you define the width of the cut. Otherwise, the width is defined by the area between two contours. Dynamic OptiRough The Dynamic OptiRough toolpath is currently the only 3D toolpath that uses Mastercam’s Dynamic Motion technology. It supports cutters capable of machining very large depths of cut. A single Dynamic OptiRough toolpath can cut material in two directions: on stepdowns (-Z) and stepups (+Z). This bi-directional cutting strategy removes the maximum amount of material with the minimum amount of stepdowns, significantly reducing cycle times. MASTERCAM 2017 FOR SOLIDWORKS TUTORIAL (MILL) 10 MASTERCAM 2017 FOR SOLIDWORKS / Introduction Similar to Dynamic Mill, you can select From outside or Stay inside when machining. However, instead of selecting regions, you select drive surfaces, check surfaces, and containment boundaries. Dynamic Toolpath Selection The Dynamic toolpaths, especially the Dynamic Mill toolpath, require a unique way of understanding chain selection. Dynamic Contour does not require a closed chain to calculate a toolpath. All geometry selected will be cut by the tool motion. Peel Mill requires at least one open chain and no closed chains.
