4. Workpiece definition Workpiece will be created by extruding the outer contour with additional stock. Workpiece definition tab Extrusion panel button Workpiece extrusion dialog Top/Bottom workpiece levels Stock Workpiece contour curve Highlighted selected curve of the workpiece contour Semitransparent view of the workpiece Contour selected as the workpiece Contents

5. Operation creation The first operation we will be using us the 2.5D pocketing operation. Operation creation dialog 2.5D pocketing Operation groups New operation Contents

6. Job assignment Selected operation Job assigment tab The job assigment will consist of forming contours. Cover Outer contour will be defined as a cover with Z level 20 Inner contour will be defined as a hole with Z level 5 This contour will be defined as a cover with Z level 15 This contour will be defined as a hole with Z level of 3 List of forming contours Contents

7. Machining parameters Active operation Operation parameters dialog Let’s examine the main parameters of the new operation. Contents

8. Machining parameters Spiral plunge Quantity of layers Additional flat areas machining Cylindrical mill Radial stock for futher machining Relief angle Contents

9. Toolpath calculation Calculate toolpath Toolpath Green tick means there are no errors during calculation Contents

10. Machining simulation Workpiece Tool Machining result of the 2.5D pocketing operation Contents

11. Operation creation Next operation – 2.5D wall machining. This operation will remove the radial stock (0.5 mm) of the previous 2.5D pocketing opeartion. Operation creating dialog Finishing operations group 2.5D wall machining Use Fill parameters otption to copy parameters of previous operation into the new one Newly created 2.5D wall machining operation Contents

12. Job assignment We used the Fill parameters option so all parameters from the previous 2.5D pocketing operation (including the Job assignment) were copied to the new operation. Therefore, there is no need to specify them because the machined elements are the same. Active operation Job assignment The list of contours is copied from the 2.5D pocketing operation Contents

13. Machining parameters We used the Fill parameters option and all technology parameters from previous 2.5D pocketing operation were passed into new operation. We only need to change the tool and set the radial stock to “0” Radial stock Arc radius Cylindrical mill D=7, L=35 Arc radius Contents
