<h1>ROTATE - MDFG Options</h1>

<p CLASS=Paragraph>This section describes the formats and parameters to 
 control the output for the fourth and fifth axes.</p>

<p CLASS=Paragraph>These are the basic four axis machine tools:</p>

<ul>
	
	<li class=kadov-p-CListBullet><p CLASS=ListBullet>A rotary table in 
 either the YZ or ZX planes.</p></li>
	
	<li class=kadov-p-CListBullet><p CLASS=ListBullet>A tilting table in 
 either the YZ or ZX planes (this is treated the same as a rotary table.)</p></li>
	
	<li class=kadov-p-CListBullet><p CLASS=ListBullet>A swiveling head 
 in either the YZ or ZX plane.</p></li>
</ul>

<p CLASS=Paragraph>These are the basic five axis machine tools:</p>

<ul>
	
	<li class=kadov-p-CListBullet><p CLASS=ListBullet>A rotary table mounted 
 on another rotary table. These can be any combination of XY, YZ, or ZX 
 planes.</p></li>
	
	<li class=kadov-p-CListBullet><p CLASS=ListBullet>A rotary table or 
 a tilting table in either the XY, YZ, or ZX planes and a swiveling head 
 in one of the planes.</p></li>
	
	<li class=kadov-p-CListBullet><p CLASS=ListBullet>Two swiveling heads 
 in any combination of XY, YZ, or ZX planes.</p></li>
</ul>

<p CLASS=Paragraph>The Independent table (or 4th axis) is the rotary axis 
 that <span style="font-weight: bold;">does not</span> change its orientation 
 or plane of rotation when the other rotary axis moves. When one axis is 
 a swiveling head and the other is a rotary table, the swiveling head is 
 the independent axis and the rotary table is the dependent axis.</p>

<p CLASS=Paragraph>The Dependent (or 5th axis) is the rotary axis that 
 <span style="font-weight: bold;">does</span> change its orientation or 
 plane of rotation when the other rotary axis is rotated. By definition 
 there must be a 4th axis in order to have a 5th axis.</p>

<h5>&nbsp;</h5>

<h5>Independent (or 4th Axis)</h5>

<p CLASS=Paragraph>When you select the 4th or 5th axis option you have 
 the following choices:</p>

<h5>&nbsp;</h5>

<h5>4th or 5th Axis</h5>

<p CLASS=ListBulletTxt><span style="font-weight: bold;">Minimum Angle Increment 
 Degrees</span> - This is the smallest amount of delta rotation possible. 
 For example, if a rotary axis has 360,000 positions the minimum increment 
 is .001. Likewise if it is a 72 position table the minimum increment is 
 5 degrees.</p>

<p CLASS=ListBulletTxt>Enter the number which represents the minimum angle 
 increment for the rotation.</p>

<h5>&nbsp;</h5>

<h5>4th or 5th Axis</h5>

<p CLASS=ListBulletTxt><span style="font-weight: bold;">Direction Of Rotation 
 Determined By</span> - This determines how the postprocessor forces either 
 clockwise or counterclockwise rotation. You have the following options:</p>

<p CLASS=ListBulletTxt
	style="margin-left: 40px;"><span style="font-weight: bold;">Sign Of 
 Angle, Plus Is CLW, Minus Is CCLW </span>- For this type of rotary axis 
 -90 will cause a counterclockwise rotation of 90 degrees and 90 will cause 
 a clockwise rotation of 90 degrees. The sign is used only to determine 
 direction of rotation.</p>

<p CLASS=ListBulletTxt
	style="margin-left: 40px;"><span style="font-weight: bold;">Table Rotates 
 CLW To A Large Angle, CCLW To A Smaller Angle </span>- (this is the most 
 common choice) For this type of rotary axis the sign is used to determine 
 the absolute angle. For instance 90 degrees and -90 degrees are different 
 positions, -90 and 270 are exactly one rotation or 360 degrees apart. 
 The rotary axis will rotate clockwise from -100 degrees to -50 degrees 
 and counterclockwise from 100 degrees to 50 degrees.</p>

<p CLASS=ListBulletTxt
	style="margin-left: 40px;"><span style="font-weight: bold;">M Codes 
 Force Direction Of Rotation </span>- The user at this point selects the 
 two M codes, one for clockwise and one for counterclockwise. The menu 
 is shown after this definitions list.</p>

<p CLASS=ListBulletTxt
	style="margin-left: 80px;">Enter the number which represent the M code 
 to force the table rotation in a clockwise direction.</p>

<p CLASS=ListBulletTxt
	style="margin-left: 80px;">Enter the number which represent the M code 
 to force the table rotation in a counter clockwise direction.</p>

<p CLASS=ListBulletTxt
	style="margin-left: 80px;">The user is then asked if the M codes for 
 direction are modal or not.</p>

<p CLASS=ListBulletTxt
	style="margin-left: 40px;"><span style="font-weight: bold;">Rotation 
 Is Always CLW </span>- The postprocessor cannot control direction of rotation 
 for this type.</p>

<p CLASS=ListBulletTxt
	style="margin-left: 40px;"><span style="font-weight: bold;">Rotation 
 Is Always CCLW </span>- The postprocessor cannot control direction of 
 rotation for this type.</p>

<p CLASS=ListBulletTxt
	style="margin-left: 40px;"><span style="font-weight: bold;">Rotation 
 Is Always Shortest Distance </span>- The postprocessor cannot control 
 direction of rotation for this type.</p>

<p CLASS=ListBulletTxt
	style="margin-left: 40px;"><span style="font-weight: bold;">Sign Of 
 Angle, Minus Is CLW, Plus Is CCLW </span>- For this type of rotary axis 
 90 will cause a counterclockwise rotation of 90 degrees and -90 will cause 
 a clockwise rotation of 90 degrees. The sign is used only to determine 
 direction of rotation.</p>

<p CLASS=ListBulletTxt
	style="margin-left: 40px;"><span style="font-weight: bold;">Rotary 
 Axis Rotates CCLW To A Larger Angle And CLW To A Smaller Angle </span>- 
 For this type of rotary axis the sign is used to determine the absolute 
 angle. For instance 90 degrees and -90 degrees are different positions, 
 -90 and 270 are exactly one rotation or 360 degrees apart. The rotary 
 axis will rotate counterclockwise from -100 degrees to -50 degrees and 
 clockwise from 100 degrees to 50 degrees.</p>

<h5>&nbsp;</h5>

<h5>4th or 5th Axis</h5>

<p CLASS=ListBulletTxt><span style="font-weight: bold;">Maximum </span>or 
 <span style="font-weight: bold;">Minimum Programmable Angle</span> - This 
 is maximum or minimum allowable rotary position measured clockwise from 
 the minimum allowable rotary position. The valid programmable rotary positions 
 are those that measure clockwise from the minimum position to the maximum 
 position.</p>

<p CLASS=ListBulletTxt>The GPM uses the <span style="font-weight: bold;">Maximum 
 </span>or <span style="font-weight: bold;">Minimum Programmable Angle</span> 
 to determine if rotary positions, derived from the tool axis, exceeds 
 these limits.</p>

<h5>&nbsp;</h5>

<h5>4th or 5 th Axis</h5>

<p CLASS=ListBulletTxt><span style="font-weight: bold;">Maximum </span>or 
 <span style="font-weight: bold;">Minimum Degrees Per Minute</span> - Enter 
 the number which represents the maximum or minimum number of degrees that 
 the 4th axis can turn per minute.</p>

<h5>&nbsp;</h5>

<h5>4th or 5 th Axis</h5>

<p CLASS=ListBulletTxt><span style="font-weight: bold;">Plane Of Rotary 
 Axis (XY, YZ, ZX) </span>- This defines in which of the three cartesian 
 planes that the rotary axis lies. To determine the plane of the 5th axis, 
 the 4th axis should be at its 0 degrees position. Generally the A axis 
 is in the YZ plane, the B axis in the ZX plane and C axis is in the XY 
 plane. Not all machine tools follow these conventions. The MDFG allows 
 you to assign both the axis letter and the axis plane of rotation. The 
 selection toggles between the three axis planes.</p>

<h5>&nbsp;</h5>

<h5>4th or 5th Axis</h5>

<p CLASS=ListBulletTxt><span style="font-weight: bold;">Rotary Axis Type 
 </span>- This option defines what transformations are needed to map the 
 part coordinates to the machine coordinates. The part coordinates are 
 not mapped to reflect the rotation if the rotary axis is not contouring.</p>

<p CLASS=ListBulletTxt>There are four types of rotary axis:</p>

<p CLASS=ListBulletTxt
	style="margin-left: 40px;"><span style="font-weight: bold;">Index Or 
 Positioning Table</span> - This type of table is not capable of contouring 
 mode. If the 4th axis is selected you must set other options that will 
 later determine what kind of indexing table is needed. Your options are:</p>

<p CLASS=ListBulletTxt
	style="margin-left: 80px;"><span style="font-weight: bold;">Word Address, 
 Rapid G Code Output With Angle</span> - This table uses Word Address formats 
 to position the table and a G code is output by the GPM.</p>

<p CLASS=ListBulletTxt
	style="margin-left: 80px;"><span style="font-weight: bold;">Word Address, 
 No Rapid G Code Output With Angle</span> - This table uses Word Address 
 formats to position the table and no G code is output by the GPM.</p>

<p CLASS=ListBulletTxt
	style="margin-left: 80px;"><span style="font-weight: bold;">Hyperdex 
 Table</span> - This index table will output a series of three M codes 
 for every ROTATE command. For example ROTATE/TABLE, 270,CCLW will cause 
 M92, M97, M90 in three consecutive blocks.</p>

<p CLASS=ListBulletTxt
	style="margin-left: 80px;">You can then enter the M Code value output 
 for clockwise and counter-clockwise rotate of the table base.</p>

<p CLASS=ListBulletTxt
	style="margin-left: 80px;"><span style="font-weight: bold;">One M Code 
 Per Stop</span> - Enter the number which represents the number of table 
 positions, that represents the M Code for table indexing (the default 
 is 15), and indicate the angular positions of the corresponding table 
 positions.</p>

<p CLASS=ListBulletTxt
	style="margin-left: 80px;"><span style="font-weight: bold;">One Character 
 Code Per Stop</span> - Enter the number of table positions controlled 
 by a single character Word Address, the character, and the angular value 
 for each of the table positions you specified.</p>

<p CLASS=ListBulletTxt
	style="margin-left: 80px;"><span style="font-weight: bold;">M Code 
 Defines Position</span> - Enter the number of table positions, the angular 
 value for each of the table positions you specified in Option 1, and the 
 M code to define each of the table positions you specified.</p>

<p CLASS=ListBulletTxt
	style="margin-left: 40px;"><span style="font-weight: bold;">Contouring 
 Rotary Or Tilting Table</span> - This type of rotary axis causes no movement 
 of the tool when the table rotates. It can consist of either a rotary 
 axis or tilting table. The tilting table is treated geometrically exactly 
 like a rotary table except that plane of rotation is not the plane of 
 the table. It is the plane that is perpendicular to the axis of the tilting 
 table.</p>

<p CLASS=ListBulletTxt
	style="margin-left: 40px;"><span style="font-weight: bold;">Contouring 
 Swiveling Head</span> - This type of rotary axis causes motion only in 
 the tool.</p>

<p CLASS=ListBulletTxt
	style="margin-left: 40px;"><span style="font-weight: bold;">Index Or 
 Positioning Head</span> - This type of rotary axis is for positioning 
 only.</p>

<h5>&nbsp;</h5>

<h5>4th or 5th Axis</h5>

<p CLASS=ListBulletTxt><span style="font-weight: bold;">Conversion Factor 
 Degrees To Rev Or Inches</span> - This option allows you to define the 
 rotary output in something other than degrees. For example, some controls 
 require revolutions and not degrees. The user would enter .002777778 to 
 make this conversion. This option is 1.0 for most controls.</p>

<h5>&nbsp;</h5>

<h5>4th or 5th Axis</h5>

<p CLASS=ListBulletTxt><span style="font-weight: bold;">Rotation Of (A,B 
 or C) Axis About (X,Y or Z) Axis Is Standard (or Reverse) Cartesian</span></p>

<p CLASS=ListBulletTxt>This parameter controls how the GPM will translate 
 the i,j,k tool axis information into rotary positions. Most NC machines 
 are <span style="font-weight: bold;">Standard</span>, that is, they rotate 
 or swivel clockwise to larger angle. When in doubt use the <span style="font-weight: bold;">Standard</span> 
 convention unless the data is incorrect for your machine tool. The following 
 guidelines can be used.</p>

<p CLASS=ListBulletTxt>In the XY plane looking down the Z axis from positive 
 to negative rotation clockwise to a larger angle is <span style="font-weight: bold;">Standard.</span></p>

<p CLASS=ListBulletTxt>In the ZX plane looking down the Y axis from positive 
 to negative, rotation clockwise to a larger angle is<span style="font-weight: bold;"> 
 Standard</span>.</p>

<p CLASS=ListBulletTxt>In the YZ plane looking down the X axis from negative 
 to position, rotation clockwise to a larger angle is<span style="font-weight: bold;"> 
 Standard.</span></p>

<h5>&nbsp;</h5>

<h5>Range Parameters</h5>

<p CLASS=ListBulletTxt><span style="font-weight: bold;">Radius From Center 
 Of Rotation To Tool Tip</span> - When you choose to Out Put To Tape, you 
 must indicate the Format for The Radius Parameter.</p>

<h5>&nbsp;</h5>

<h5>4th or 5th Axis</h5>

<p CLASS=ListBulletTxt><span style="font-weight: bold;">Distance From Pivot 
 Point To Spindle Gage Line</span> - This option is available when you 
 select <span style="font-weight: bold;">Index Or Positioning Swivel Head 
 </span>under the option <span style="font-weight: bold;">Rotary Axis Type</span>. 
 Enter the number which represents the distance from the pivot point to 
 the spindle gage point.</p>

<h2>&nbsp;</h2>

<h2>How to Reset Rotary Tables</h2>

<h5>&nbsp;</h5>

<h5>4th or 5th Axis</h5>

<p CLASS=ListBulletTxt><span style="font-weight: bold;">Reset Rotary Table 
 - </span>This option allows you to set the parameters for resetting the 
 rotary table.</p>

<p CLASS=ListBulletTxt
	style="margin-left: 40px;"><span style="font-weight: bold;">Retract 
 Before Resetting Table - </span>Toggles between YES and NO. If set to 
 YES, the following menu options become available allowing you to set parameters 
 for retracting from and reengaging the rotary table. For a detailed description 
 of these options, please refer to the discussion under Travel Limit Violations 
 beginning on page .</p>

<p style="text-align: left; margin-left: 160px;"
	align=left><span style="font-weight: bold;">Entry Complete -</span>When 
 you select <span style="font-weight: bold;">Entry Complete</span> the 
 <span style="font-style: italic;">Reset Rotary Table </span>menu is displayed.</p>

<p CLASS=ListBulletTxt
	style="margin-left: 40px;"><span style="font-weight: bold;">Reset Block 
 - </span>Allows you to<span style="font-weight: bold;"> </span>set the 
 parameters for setting the reset block.</p>

<p CLASS=ListBulletTxt
	style="margin-left: 80px;"><span style="font-weight: bold;">Rotary 
 Axis Only - </span>Allows you to define how the GPM will respond when 
 the desired rotary motion violates the machine's axis limits.</p>

<p style="text-align: left; margin-left: 200px;"
	align=left><span style="font-weight: bold;">Output G92 To Reset Previous 
 Rotary Position To Maintain Current Desired Or Shortest Rotation -</span></p>

<p style="text-align: left; margin-left: 200px;"
	align=left><span style="font-weight: bold;">Output Valid Rotary Position 
 Closest To Previous Position -</span></p>

<p CLASS=ListBulletTxt
	style="margin-left: 80px;"><span style="font-weight: bold;">Unwind

 to specify the unwind code.</p>

<p CLASS=ListBulletTxt
	style="margin-left: 80px;"><span style="font-weight: bold;">Unwind 
 Code and Rotary Axis - </span>Allows you to enter a text string of up 
 to 66 characters to specify the unwind code, then displays the <span style="font-weight: bold;">Rotary

<h5>&nbsp;</h5>

<h5>Word Address Format for 4th or 5th Axis</h5>

<p CLASS=ListBulletTxt><span style="font-weight: bold;">Entry Complete</span> 
 - When you select <span style="font-weight: bold;">Entry Complete</span> 
 the <span style="font-style: italic;">Word Address Character</span> menu 
 is displayed.</p>

<h5>&nbsp;</h5>

<h5>Angular Offsets for 4th or 5th Axis</h5>

<p CLASS=ListBulletTxt>Next, you can enter the number of degrees (if any) 
 of angular offset between the rotary component 0 degree position and the 
 expected 0 degree position. The expected 0 degree position is straight 
 down (negative along) the Z axis (i.e., when the tool axis is 0, 0, 1.)</p>

<p CLASS=ListBulletTxt>The angular offset value is the rotary axis value 
 when the MCS tool axis is 0,0,1. For example, the Sundstrand OM4 A axis 
 0 position is with the spindle pointing down the machine Y axis. Since 
 a 0,0,1 tool axis produces an A axis reading of 90_ the angular offset 
 value is 90_.</p>

<p CLASS=ListBulletTxt>Several manufacturers use a position 90 degrees 
 CCLW (i.e., looking positive along the X axis) from the expected position. 
 Next one of two menus appear:</p>

<h5>&nbsp;</h5>

<h5>4th Axis Only</h5>

<p CLASS=ListBulletTxt>Using the <span style="font-weight: bold;">Machine 
 Zero To Center Of Forth Axis</span> menu, you can indicate that machine 
 tool's zero position is not at the center of the rotary table. In order 
 for the post to correctly map the part coordinate system to the machine 
 coordinate system, this number must be correct. Enter the number which 
 represents the X, Y, and Z delta distance. This should be entered in machine 
 coordinates from machine zero to the center of the fourth axis.</p>

<h5>&nbsp;</h5>

<h5>5th Axis Only</h5>

<p CLASS=ListBulletTxt>Using the <span style="font-weight: bold;">Center 
 Of Fourth Axis To</span> <span style="font-weight: bold;">Center Of Fifth 
 Axis</span> menu (which actually means the center of the fifth axis to 
 the center of the fourth axis), you can indicate that the 5th axis of 
 rotation axis does not intersect the 4th axis of rotation. To derive this 
 vector, both axis should be at zero degrees and it involves at most two 
 coordinates but usually one. This perpendicular vector is measured in 
 the plane of the 4th axis from the axis of rotation of the 5th axis to 
 the axis of rotation of the 4th axis. You are prompted to specify whether 
 a RESET code (G92) is output when the axis limits are violated.</p>

<p CLASS=ListBulletTxt><span style="font-weight: bold;">Inclination Of 
 B Axis To C Axis</span> - (special option) The initial implementation 
 is for two swiveling heads, one in the XY plane, the other is inclined, 
 but the 0 position lies in the ZX plane. To utilize this configuration, 
 you must make these selections under ROTATE: Both heads must be contouring 
 swiveling heads. The 4th axis must be in the ZX plane and the 5th axis 
 must be in the XY plane.</p>

<p CLASS=ListBulletTxt>If the above conditions exist, the MDFG will ask 
 if the B axis is inclined to the C axis at other than 90 degrees. B refers 
 to the ZX plane and C refers to the XY plane. The actual letter addresses 
 used is not significant, but the planes must be ZX for the 4th axis and 
 XY for the 5th axis. If the axes are inclined, you will be asked to enter 
 the number of degrees. GPM will resolve the B and C angles to align with 
 the tool axis vector in the CLF file.</p>

<h5>&nbsp;</h5>

<h5>Considerations</h5>

<p CLASS=ListBulletTxt>If you are using a five axis machine tool with a 
 rotary or tilting table and a pivoting head, the pivoting head is always 
 the fourth axis.</p>

<p CLASS=ListBulletTxt>If a pivoting head is mounted to a rotary fifth 
 axis, then you must define <span style="font-style: italic;">both</span> 
 the fourth and fifth axes as swiveling heads.</p>

<p CLASS=ListBulletTxt>A tilting table is always a fourth axis - never 
 a fifth - and is defined as a tilting or rotary table. It can require 
 the reverse cartesian option.</p>

<p CLASS=ListBulletTxt>The C axis (XY plane) is never a fourth axis.</p>

<p CLASS=ListBulletTxt>Program the machine coordinate system at the center 
 of the fifth axis rotary table for all pivot head/rotary table machine 
 combinations when the rotary table is in the machine bed. Examples are 
 the Sundstrand OM3, OM4, M60, and M80. This also applies to tilting/rotary 
 table machines such as the 5 axis K&amp;T and all double rotary table 
 combinations.</p>

<p CLASS=ListBulletTxt>For incremental rotary output to cross quadrants 
 correctly, the limits must be set to +- 99999.99.</p>

<ul>
	
	<li class=kadov-P-CNote><p CLASS=Note><span style="font-weight: bold;">NOTE:</span> 
 You might find it beneficial to build a simple test.cls that repeatedly 
 uses GOTO 0,0,0 with i, j, k vectors to test all reasonable rotary combinations 
 and axis limits. You can easily set up a part file that represents your 
 machine tool with the pivot points defined. Then rotate that geometry 
 about the pivot points and verify the positions using the option Verify 
 Points. The GPM output points should equal the WCS values.</p></li>
</ul>
