● ShopTurn assists you even when entering the technological values: You only have to the handbook values "feedrate" (or feed) and "cutting rate" – the speed is calculated by ShopTurn automatically. ● ShopTurn enables you to describe a complete machining operation with one machining step, and the required positioning motions (in this case, from the tool change point to the workpiece and reverse) are created automatically. ● All machining steps are represented by ShopTurn in a compact and clear fashion in the graphic machining plan. This provides you a complete overview and thus better editing possibilities even for comprehensive machining sequences. ● For stock removal, for example, several machining operations and contours can be linked. ● The integrated contour calculator can process all standard dimensions (Cartesian and It is nevertheless very easy to handle and understand – thanks to colloquial input and graphic support. ● You may switch between the graphic view and parameter screen form with help screen at any time. ● The creation and the machining of the machining plan are not mutually exclusive. With ShopTurn, you can create a new machining plan in parallel with machining. You save machining time: ● You can optimize tool selection for the stock removal of contours: Large volumes are removed using roughing tools, and residual material ① is detected and removed automatically using a pointed tool. ● The ability to pinpoint the selected retraction plane means that unnecessary traversing motions can be avoided, thereby saving valuable machining time. This is possible using the settings "Simple", "Extended" and "All". Retraction plane: Simple Retraction Extended Retraction plane: All
● You can optimize your machining sequence with minimum effort – thanks to the compact structure of the machining plan (in this case, by saving of a tool change, for example). Figure 2-6 Original machining sequence Figure 2-7 Optimized machining sequence with cutting and pasting ● With ShopTurn, you can achieve extremely high feedrates with optimum repeat accuracy based on integrated digital technology (SINAMICS drives, etc., SINUMERIK controllers). To ensure that everything function smoothly In this section, you will the basics of the operation of ShopTurn with the help of examples. The operation of ShopTurn Powerful software is important, but it also has to be intuitive to operate. Regardless of whether you work with SINUMERIK 840D sl or SINUMERIK 828D as shown here, you are always assisted by the clearly laid-out machine operator panel. The operator panel consists of 3 parts – the flat operator panel ①, the CNC full keyboard ② and the machine control panel (MCP) ③.
The most important keys on the CNC full keyboard for navigation in ShopTurn are listed in the following: Key Function <HELP> • Calls the context-sensitive online help for the selected window. <SELECT> (also called Toggle key) • Selects a listed value. Cursor keys • The cursor is using the four cursor keys. • Use the <Cursor right> key shown here to open a directory or program (e.g. a cycle) in the editor in edit mode. <PAGE UP> • Scroll upwards in a menu screen. <PAGE DOWN> • Scroll downwards in a menu screen. <END> • the cursor to the last text box in a menu screen or table. <DEL> • Edit mode: Deletes the character to the right. • Navigation mode: Deletes all characters. <BACKSPACE> • Edit mode: Deletes a character selected to the left of the cursor. • Navigation mode: Deletes all of the selected characters to the left of the cursor. <INSERT> • Press the key to enter Edit mode. Press the key again to exit Edit mode and go to Navigation mode. <INPUT> • Complete input of a value in the text box. • Open a directory or program. The actual function selection in ShopTurn is performed using the keys located
The mean value is selected: f = 0.3 mm Relationship between feed and feedrate: The constant feed f and the respective speed n yield the feedrate: Vc = 180 m/min Vf = f * n Vc = 180 m/min d2 = 80 mm d2 = 20 mm n2 ≈ 710 rpm n2 ≈ 2800 rpm Vf2 ≈ 710 rpm * 0.3 mm Vf2 ≈ 2800 rpm * 0.3 mm Vf2 ≈ 210 mm/min Vf2 ≈ 840 mm/min Since the speed is different, the feedrate also differs for the various diameters, despite having the same feed. Effective setup In this section, you will learn how to create the tools required for the examples in the following sections. Furthermore, the offset of the tool lengths and the setting of the workpiece zero is explained with examples. Tool management ShopTurn offers three lists for tool management: ● Tool list ● Tool wear list ● Magazine list Tool list The tool list displays all parameters and functions required to create and set up the tools.
