[. . . ] User's Manual MANUALplus 620 smart. Turn and ISO Programming NC Software 548 328-02 V2 English (en) 4/2010 MANUALplus 620, smart. Turn and "DIN PLUS" Programming This manual describes the smart. Turn and "DIN PLUS" (ISO) programming features of the MANUALplus 620. The manual takes into account functions provided by the MANUALplus 620 as of the NC software number 548 328-02. Machine operation and cycle programming are described in the MANUALplus 620 User's Manual (ID 634 864-xx). Please contact HEIDENHAIN if you require a copy of this manual. [. . . ] Radial recess: First Z, then X direction Axial recess: First X, then Z direction 3 4 5 6 7 Executes the first cut according to I. Returns at rapid traverse and approaches for next pass. If I=0: Dwells for time E Repeats 3 to 4 until the complete recess has been machined. If I>0: Finish machines the contour HEIDENHAIN MANUALplus 620 261 4. 17 Contour-Based Turning Cycles 4. 17 Contour-Based Turning Cycles Finish contour G890 G890 finishes the defined contour area in one pass. The reference to the contour to be machined can be transferred in the cycle parameters, or the contour can be defined directly after the cycle call (see "Working with contour-based cycles" on page 246). The contour to be machined may contain various valleys. If required, the area to be machined is divided into several sections. Parameters ID NS NE Auxiliary contour--ID number of the contour to be machined Starting block number (beginning of contour section) End block number (end of contour section) NE not programmed: The contour element NS is machined in the direction of contour definition. NS=NE programmed: The contour element NS is machined opposite to the direction of contour definition. E Plunging behavior E=0: Descending contours are not machined. E>0: Plunging feed rate No input: Descending contours are machined at programmed feed rate V Identifier start/end (default: 0) A chamfer/rounding arc is machined: 0: At start and end 1: At the start 2: At the end 3: No machining 4: Chamfer/rounding arc is machined--not the basic element (prerequisite: Contour section with one element) Q Type of approach (default: 0) 0: Automatic selection--the MANUALplus checks: Diagonal approach First X, then Z direction Equidistant around the barrier Omission of the first contour elements if the starting position is inaccessible 1: First X, then Z direction 2: First Z, then X direction 3: No approach--tool is located near the starting point of the contour area. 262 ISO Programming Parameters H Type of retraction (default: 3). Tool backs off at 45° against the machining direction and moves as follows to the position I, K: 0: Diagonal 1: First X, then Z direction 2: First Z, then X direction 3: Stops at safety clearance 4: No retraction motion--tool remains on the end coordinate 5: Diagonally to the tool position before the cycle call 6: First in X, then in Z to the tool position before the cycle call 7: First in Z, then in X to the tool position before the cycle call X Z D Cutting limit (diameter value)--(default: no cutting limit) Cutting limit (default: no cutting limit) Omit elements (default: 1). Use the omit codes listed in the table at right to omit individual elements, or the omit codes listed in the table at the lower right to skip execution of recesses, undercuts and relief turns. End point that is approached at the end of the cycle (diameter value) End point that is approached at the end of the cycle Feed rate reduction for circular elements (default: 0) 0: Feed rate reduction is active 1: No feed rate reduction U Cycle type--Required for generating the contour from the G80 parameters. (default: 0) 0: Standard contour (longitudinal or transverse), recessing contour or ICP contour 1: Linear path without/with return 2: Circular arc CW, without/with return 3: Circular arc CCW, without/with return 4: Chamfer without/with return 5: Rounding arc without/with return B Tool-tip radius compensation (default: 0) 0: Automatic determination 1: To the left of the contour 2: To the right of the contour The MANUALplus uses the tool definition to distinguish between external and internal machining. Undercuts are machined if they are programmed and if tool geometry permits.

Feed rate is not programmed with G95-Geo: Automatic feed rate reduction. Each chamfer/rounding is therefore machined with at least three revolutions. For chamfers/rounding arcs which, as a result of their size, are machined with at least three revolutions, the feed rate is not reduced automatically. For circular elements, the following applies: For small circular elements, the feed rate is decreased until every element is machined with at least four spindle revolutions. You can switch this feed rate reduction off with O.
