CNC – 50 Hour Programming Course

2 1.1 Introduction This appendix will cover the programming of a lathe with 4 axes (X, Z, Y, C). The machine is essentially the same as that analysed in the book with the added possibility of moving the turret along the transversal axis on plane G18. As already seen in paragraph 4.5, the Y-axis gives the lathe greater flexibility when executing milling operations.

The ISO functions presented during the course were first used on the X-Z (G18) turning plane; then in Chapter 32 they were used to define the profile to be milled on the X-Y (G17) plane; now they are used to program the milling operations carried out on the Y-Z (G19) plane.

3 The programming concepts for each single function are exactly those already presented in the chapters contained within the book. A programming scheme remains to be established to determine: - the clockwise and anticlockwise directions of the circle arcs, - the right and left position of the tool compared to the profile of the part, - the value of the angles to be used in direct programming. The programming scheme to be used is that already analysed in paragraph 4.9.

Fig. 2. Programming scheme for all work planes


4 1.2 Specific programming scheme for plane G19 So as to use correctly the programming scheme, it must be positioned according to the positive direction of the axes present in the machine, the tool's intended trajectory must be evaluated and the correct function to be used must be chosen. Below is the specific scheme to be used on the Y-Z work plane.

Fig. 3. Specific programming scheme for the Y-Z plane

1.3 Programming example Programming for the following work piece starts with the application of the scheme in Figure 3.

Fig. 4. Programming example with work on the Y-Z plane


5 1.3.1 Y-axis positive direction In a lathe, the zero point of the Y-axis is located (as for the X-axis) on the rotation axis of the part. The tool's direction of movement (indicated by the red arrow) shows that the mill is moving from Y negative to Y positive.

8 1.3.2 Circular interpolation As can be seen in Figure 4, the path to be followed is symmetrical relative to the Z-axis. After flattening, the program continues with the completion of the remaining half in the positive Y quadrant. The red arrow indicates that the mill, to make the radius, turns clockwise; based on the programming scheme, the function to be used is therefore G2 (see Chapter 13).

1.3.3 Direct programming of radii, chamfers and angles After the radius, the profile continues with a line parallel to the Z-axis which connects with a radius to the following straight line inclined at 45°. The direct programming of radii, chamfers and angles occurs according to the same concepts and functions present in chapter 12. Aligning the programming scheme in Figure 3 with the positive direction of the axes, it results that the angle value to be programmed is 225°.

1.3.4 MIRROR: Programmable mirror function The upper part of the profile happens to be a perfect mirror image of the lower part. The MIRROR function allows for the inversion of the positive direction of one or more axes.


11 In order to create the upper profile, the program repositions the mill at the start point of the lower profile (co-ordinates Y0, Z-5, X29), activates the mirroring of the Y-axis (MIRROR Y0) and repeats the blocks programmed between the buttons ‘START:’ and ‘END:’. The MIRROR function (programmed without the name of any axis) deactivates the mirror function.

Practice

1.4.1 Introduction The lathe on which this practice is carried out is not yet present in the simulation software. We will therefore create it and load the programs and the tools used.

1.4.2 Creation of the Y-axis lathe Once the program SinuTrain Operate has been initiated, click on the icon NEW located on the high part of the screen and select the first option proposed, which is to Create a new machine configuration from a template, then press NEXT. In this window there appears the list of standard machine models preconfigured in SinuTrain, select Lathe with driven tool, Y-axis and counter spindle and press NEXT. Now choose the name of the lathe, describe its basic characteristics and set the language and the size of the window which plays the video of the machine according to the information reported below. GENERAL

Machine name: LATHE: with Y-axis and counter spindle Description: SP1: main spindle’s name, X: radial linear axis, Y: transversal linear axis, Z: longitudinal linear axis, SP3: name of the spindle for motorised tools, SP2: name of the counter spindle

LANGUAGE

1.4.3 Download of the programs and transfer to SinuTrain Open the web page www.cncwebschool.com, log in to the area APPENDIXES, click on PROGRAMS USED IN APPENDIX 1 to download the folder which contains the programs. Select with the cursor the compressed folder once downloaded, rightclick with the mouse and select: Extract all, Next, Next. Copy folder A1_PROG to an empty USB memory storage. On the control panel click PROGRAM MANAGER. Select from the horizontal USB softkeys, the content of the external memory will appear on the screen. Select with the arrow the folder A1_PROG then press the yellow button INPUT to open it. Now go down to the orange bar and select folder A01_01. From the vertical softkeys, press MARK and move down with the arrow selecting all the contents of the folder.


14 Press COPY. Press NC from the horizontal softkeys. Select with the arrow the folder WORKPIECES and press PASTE from the vertical softkey. Now all the programs and the file that contains the tools’ tooling data are available for use. 1.4.4 Importation of the tool data Press PROGRAM MANAGER and then enter folder A01_01, select with the arrow the file TOOL_APP_01 and press the yellow key INPUT, the NC recognises that you want to load the tool data. Then press OK and confirm, by pressing OK again, that you want to overwrite the current data. 1.4.5 Activation of the graphic simulation Open program ‘PRG_01’ contained in folder ‘A01_01’. This program creates the part shown in Figure 3. Activate the graphic simulation in a single block and analyse the movement of the tool based on the current program block, referring to the comments in the previous paragraphs for help. You can download the video from cncwebschool.com's YouTube channel. In the APPENDIXES section you will also find the pocket 3D model of the programming scheme to be used on the various work planes.
