22、oftware for manufacturing complex shapes typically found in the toolmaking, automotive, and aerospace industries. PowerMILL 2010 offers all of the original features of PowerMILL 10.0, but with numerous improvements. The most significant improvements are described in this document. This document is s
23、till in the process of being written. This is not a complete list of all the improvements. A complete Whats New will be available in time for the full release of PowerMILL 2010. Toolpath preparation There are several changes to the Tool axis dialog (see page 6). !There are two new tilt methods on th
24、e Collision avoidance tab (see page 7) and a new smoothing option. !You can now smooth (see page 10) the tool axis different ways. !There is a new tab of Orientation vector (see page 14). This enables you to control the orientation of the tool which is particularly useful when working with an asymme
25、tric machine head. There are several changes to the Tool dialog (see page 19). !There are improvements to Overhang in the Tool Holder tab (see page 19). Summary of new features 2 Summary of new features PowerMILL 2010 Whats New !There is a new tab of Holder Profile (see page 21) which gives a fast w
26、ay of collision checking. A new Workplane Editor toolbar (see page 29) replaces the Workplane dialog and the workplane options on the Curve Editor toolbar in previous versions. There are additions to the Curve Editor toolbar (see page 47). You can: !Edit points; !Reverse selected items; !Interactive
27、ly edit simple curves (lines, arcs, circles, and polylines); !Input coordinates on the status bar; !Use context menus for simple curves. There are several improvements to boundaries (see page 72). !The calculation of 3D offsetting is run in multiple threads. So it is noticeably faster on multi-core
28、machines. !You can now create two types of boundary offsets (see page 72). !There is a new option on the Silhouette Boundary (see page 73) which prevents spikes occurring on near vertical surfaces. Models now have a date (see page 74) showing when they were imported into the project. There are a cou
29、ple of enhancements to stock models (see page 75). !There are additional options to the individual stock model menu. !There is a new Stock Models tool state menu (see page 78). Toolpath generation Many of the existing machining strategies now use the new style machining strategy dialog (see page 85)
30、. This is a tabbed dialog where the pages are selected from the tree in the left hand panel. It is simpler to use and provides an easier way to create toolpaths. Most of the Area clearance dialogs (see page 86) now use the new style strategy dialog. As well as converting them to the new style, there
31、 has also been a change in the way strategies are displayed in the Strategy Selector dialog. Other enhancements include: !Avoiding the machining of thin slivers (see page 88) of material which appear on the block edge towards the end of machining an area. PowerMILL 2010 Whats New Summary of new feat
32、ures 3 !Improved ordering (see page 89). There is a new Steep and shallow finishing strategy (see page 90) which calculates a shallow boundary, and then creates Constant Z toolpath in the steep areas of a model and Raster or 3D offset toolpath in the shallow areas. There is a new Corner finishing st
33、rategy (see page 109) which removes material left in corners. The toolpath is generated such that the rest material is removed in successive stages, using horizontal and vertical stitch movements, or along passes. Finishing strategies now have the option to allow the tool centre to go outside the bl
34、ock (see page 122). The Cusp height and Stepover (see page 124) are now linked on finishing dialogs. There is a new option of Smoothing (see page 126) on the 3D offset finishing dialog. There are a couple of new options on the Constant Z finishing dialog (see page 127): !Machine down to flats (see p
35、age 129). !Unsafe segment removal (see page 132). You can now view a single Z height (see page 136) of a toolpath. Surface finishing has a new option of Degouge tolerance (see page 142). You can now create Holes (see page 142) from the Drilling dialog. Disc profile finishing now has the option to li
36、ft or trace for gouge avoidance. As with PowerMILL 10.0 one of the most important, but least visible improvements in PowerMILL 2010 is the use of parallel processing (see page 149). 4 Summary of new features PowerMILL 2010 Whats New Toolpath verification There are several enhancements to toolpath ve
37、rification (see page 150): !When verification splits a toolpath, the leads and links are preserved where appropriate, on the resulting toolpaths. !Simulation can now synchronise the movement of two axes of a robot. !ViewMill now allows a negative overhang. !The Table attach point at the top of an .m
38、td file now defines the position of the PowerMILL origin. Toolpath output This topic has not been fully documented yet. User interface All the Open and Save dialogs now have customisable buttons (see page 152). Entities in lists are shown using the same folder structure (see page 153) and icons as i
39、n the explorer. General enhancements You can now create a custom toolbar (see page 156) which can contain: menu options; toolbar buttons; commands; and macros; that you use frequently. The user definable values available under Tools Options are system parameters (see page 162). There is a new Expres
40、sion Editing toolbar (see page 163) which provides a fast and easy way to create and calculate expressions in PowerMILL fields. Typed coordinates are now entered in the Status bar (see page 167) rather then on the Curve Editor toolbar. When you start PowerMILL 2010 for the first time you are asked i
41、f you want to upgrade to the new tool database (see page 155). PowerMILL 2010 Whats New Summary of new features 5 Preview This topic has not been fully documented yet. 6 Toolpath preparation PowerMILL 2010 Whats New Tool axis There are several changes to the Tool axis dialog. !There are two new tilt
42、 methods on the Collision avoidance tab (see page 7) and a new smoothing option. !You can now smooth (see page 10) the tool axis different ways. !You can smooth the Elevation and Azimuth angles independently. !There are new stepped smoothing options which keep the elevation or azimuth angle constant
43、 without changing the angle by more than a specified amount. !There is a new tab of Orientation vector (see page 14). This enables you to control the orientation of the tool which is particularly useful when working with an asymmetric machine head. !To enable the Orientation vector there is an extra
44、 option on the Definition tab (see page 18). !Collision avoidance works better for disc cutters. Toolpath preparation PowerMILL 2010 Whats New Toolpath preparation 7 Collision avoidance (Tool axis) There are several changes to the Collision avoidance tab: !There are two new Tilt methods (see page 8)
45、. !The tilt tool axis options remain unchanged, but have been reorganised. The Specify direction option replaces all the individual direction options. Selecting this option means that if a collision is detected, the tool will tilt such that the tool tip tries to point towards or away from geometry s
46、pecified in the Specified direction frame. The Specified direction frame only becomes available when you select a Tilt method of Specify direction. The options displayed in this frame are exactly the same as those available in previous versions. 8 Toolpath preparation PowerMILL 2010 Whats New !There
47、 is a new option of Smoothing distance which enables smooth tool axis changes. To prevent sudden changes in the tool axis, the tool starts tilting before the collision is detected. This distance is the Smoothing distance. For more information see Smoothing (see page 10). Tilt method (Tool axis) Ther
48、e are three new Tilt method options: Lead then Lean - if a collision is detected, the tool will tilt from the original axis in the Lead direction until the collision is avoided. If the collision cant be avoided by tilting the tool in the Lead direction, the tool will tilt in the Lean direction until
49、 the collision is avoided. Lean then Lead - if a collision is detected, the tool will tilt from the original axis in the Lean direction until the collision is avoided. If the collision cant be avoided by tilting the tool in the Lean direction, the tool will tilt in the Lead direction until the collision is avoided. These two ne
