A: Principles

Points on the machine

Machine reference points

EMCO milling machine reference pointsN (T) = Tool zero point The tool zero point N (T) lies exactly at the cutting point of the spindle axis with the front part of the milling spindle.The tool zero point is the start point for measuring the tools.

N (T)

W

R

M

Instructions:The actual reference points may have been defined at other positions, depending on the machine type. In any case, the information in the operation manual for the relevant machine applies!

M = Machine zero pointThe machine zero point M is an unchangeable reference point defined by the manufacturer.The entire machine is measured from this point.The machine zero point M is the origin of the coordinate system.

W = Workpiece zero pointThe workpiece zero point W can be freely pro-grammed by the user. By programming a work-piece zero point, the origin of the coordinate system will be shifted from the machine zero point M to the workpiece zero point W.The workpiece zero point W is the start point for the measurements in the parts program.

R = Reference pointThe reference point R is a firmly defined point on the machine which is used to calibrate the measurement system. The reference point must be approached each time after the machine is switched on, in order to make the exact distance between the points M and N (T) known to the control system.

A2 Fanuc 31i Mill

PrinciPles

Milling machine reference systemWith a reference system, you define positions in a plane or in space unambiguously. Positional information always relates to a given point and is described by means of coordinates.In the right-angled system (Cartesian system), three directions are defined as X, Y and Z axes. The axes are perpendicular respectively to one another and intersect in one point, the zero point. One coordinate gives the distance to the zero point in one of these directions. This is how you describe a position in a plane by means of two coordinates and in space by means of three coordinates.

Coordinates that relate to the zero point are described as absolute coordinates. Relative coordinates are related to any other random po-sition (reference point) in the coordinates system. Relative coordinate values are also described as incremental coordinate values.

When machining a workpiece on a milling ma-chine, you refer in general to the Cartesian co-ordinates system. The picture on the left shows how the Cartesian coordinates system is assigned to the machine axes. The three-finger right hand rule serves as an aide memoire: If the middle finger is pointing in the direction of the tool axis from workpiece to tool, then it is pointing in the Z+ direction, the thumb in the X+ direction and the index finger in the Y+. direction.

A3 Fanuc 31i Mill

PrinciPles

Polar coordinatesIf the production drawing is dimensioned or-thographically, you create the machining program with Cartesian coordinates also. For workpieces with arcs or angles, it is often easier to determine positions with polar coordinates.

In contrast to the Cartesian X, Y and Z coordi-nates, polar coordinates describe only positions in a plane. Polar coordinates have their zero point in the pole.This is how a position in a plane is unambiguously determined by means of:

• Polar coordinates radius (RP): the distance from the pole to the position.

• Polar coordinates angle (AP): The angle be-tween the angle reference axis and the path that connects the pole with the position.

(See picture above left)

Determining the pole and the angle reference axisDetermine the pole by means of two coordinates in the Cartesian coordinate system in one of the three planes. This is also how the angular refer-ence axis for the polar coordinates angle (AP) is assigned unambiguously.

PrinciPles

Absolute and incremen-tal workpiece positionsAbsolute workpiece positionsIf the coordinates of a position are related to the coordinates zero point (origin), these are de-scribed as absolute coordinates. Each position on a workpiece is determined unambiguously by its absolute coordinates.

Example 1: Drillings with absolute coordinates

Drilling 1 Drilling 2 Drilling 3X = 10 mm X = 30 mm X = 50 mmY = 10 mm Y = 20 mm Y = 30 mm

Incremental workpiece positionsIncremental coordinates refer to the last pro-grammed position of the tool, which serves as the relative (conceptual) zero point. Incremental coordinates describe the actual paths of the tool. Consequently, it is also described as chain measurement.

You mark an incremental dimension by means of an «I» in front of the axis designation.

Example 2: Drillings with incremental coordinates

Absolute coordinates of the drilling 4IX = 10 mmIY = 10 mm

Drilling 5, related to 4 IX = 20 mm IY = 10 mm

Drilling 6, related to 5IX = 20 mmIY = 10 mm

Zero point shift of machine zero point M to tool zero point W

MW

Zero point offsetOn EMCO milling machines, the machine zero point «M» is on the left front edge of the machine table. This position is unsuitable as a start point for programming. Using the so-called zero point offset, the coordinate system can be shifted to a suitable point in the machine working area.

A distinction is made between the following zero point offsets:• Machine coordinate systems (MCS) with the

machine zero point M• Basic zero point system (BNS)• Configurable zero point system (CZS)• Workpiece coordinate system (WCS) with work-

piece zero point W.

Machine coordinate system (MCS)After approaching the reference point the NC position displays of the axis coordinates are rela-tive to the machine zero point (M) of the machine coordinate system (MCS).Workpiece change points are defined in the ma-chine coordinate system.

Base zero point (BZS).If a base shift is performed in the machine coor-dinates system (MCS), a base zero point offset is the result (BZS). With this, for example, a palette zero point can be defined.

Configurable zero point system (CZS)Configurable zero point offsetIf a configurable zero point system (G54-G599) is performed from the base zero point system (BZS), a configurable zero point system (CZS) is the result.

Programmable coordinate transformation (Frames)Programmable coordinate transformations (frames) shift the originally selected workpiece coordinate system to another position, to rotate, scale or mirror it.

Workpiece coordinate system (WCS)The program for executing the workpiece is rela-tive to the workpiece zero point (W) of the work-piece coordinate system (WCS).

Machine zero point and workpiece zero point are usually not identical. The distance between the points is the entire zero point offset and is made up of various shifts:

1 With basic offset, the basic zero point offset (BNS) is generated with the range zero point.

2 With variable zero point offset (G54-G599) and with frames, zero point systems are defined for workpiece 1 or workpiece 2.

3 With programmable coordinate transformation (frames), workpiece coordinate systems (WKS) are defined for workpiece 1 or workpiece 2.

PrinciPles

Milling operationsDown-cut MillingIn down-cut milling, feed direction and cutting direction of the mill are identical.The cut penetrates the surface of the raw part in the material initially.It is advantageous that a larger chamfer angle enables the immediate penetration of the blade into the material. It is not as with up-cut milling, in which a specific sliding cutting path is left behind under pressure and friction.In down-cut milling, the feed force supports the feed drive in the same direction of rotation. With machines with play in the feed drive, jerky move-ments which lead to damage to the cut occur.

Down-cut milling is generally to be preferred if the machine permits it (backlash-free table drive in EMCO CNC machines).

Up-cut MillingIn down-cut milling, feed direction and cutting direction of the mill are identical.The tool’s cuts meet in a very sharp angle (j = 0) on the material.Before the blades penetrate into the material, they slide with increasing contact force a little piece on the surface. After penetration, the chip cross-sec-tion slowly increases and then falls away quickly.

Up-cut milling is preferred with unstable machine conditions (machines constructed conventionally) and should be used with higher rigidity materials.

Down-cut/up-cut millingDown-cut/up-cut milling is a combination of down-cut and up-cut milling.

Tool dataThe object of tool data capture is that the software uses the tool tip or the tool centre point and not the tool housing reference point for positioning.

Each tool used for machining must be measured. The distance from the cutting tip to the tool hous-ing reference point must also be determined.

The measured lengths and mill radius can be stored in the tool list.

The mill radius information is only necessary if a mill radius compensation or a milling cycle is selected for the relevant tool!(See chapter F Tool Management)

Cycle descriptionThe interior of a pocket machining profile is cut out spirally. The following tool track is generated.

For a pocket machining profile, several island machining profiles and several cavity machining profiles can be defined. Island machining profiles remain unmachined. Cavity machining profiles are bypassed so that they are not machined.

The tool track is produced in a manner such that a collision to be expected with pocket machining profiles or island machining profiles is avoided.

The tool track generated is effective, as retraction in the direction of the tool axis is avoided as far as possible. Infeed machining in the tool axis direction is possible with this tool track.

Only given machine allowances can be used. Machining can be designed either for upcut or for downcut machining. The machining direction around the islands is controlled automatically.

It is possible to cut into the machining profile from the inside and from the outside. If a residue that has not been cut away remains at a corner, it is possible to determine this auto-matically and cut it away.

It can be cut at any angle in the tool axis direction. This also determines the machining start point automatically.

The movement method for tool movement can be selected. However, a cutting depth on the top surface of island machining profiles can also be determined automatically.

In the following pocket machining profile, where the tool can move through the pocket, the tool is lifted off automatically, do that only the pocket area that has to be processed is machined.

If a number of cuts have to be made in the tool axis direction, each area is machined completely before another is started.

If a number of cuts have to be made in the tool axis direction, each area is machined completely before another is started.

Brief description of G-commands

G00 Rapid traverse

FormatN…. G00 X… Y… Z…

The carriages are traversed at maximum speed to the programmed objective (tool change position, start point for the next machining process).

Notes

• A programmed carriage feed F is suppressed during G00.

• The rapid traverse speed is set to fixed.

• The feed offset switch is limited to 100%.

Format….N… G01 X… Y… ,C/,RN… G01 X… Y…

Notes

• Programming chamfers and radii is possible only for the active plane in each case. What fol-lows defines the programming for the XY plane (G17).

• The movement which is programmed in the second block must begin with point b in the diagram. With incremental programming, the distance from point b must be programmed.

• In individual block mode, the tool stops first at point c and then at point d.

The following situations cause an error message: • If the travel in one of the two blocks G00/G01 is

so small that no intersection point was gener-ated when the chamfer or radius was entered, error message no. 55 is generated.

• If no G00/G01 command is programmed in the second block, error message no. 51 or 52 is generated

Notes

• Missing intersection points must not be calcu-lated.Angles (,A), chamfers (,C) and radii (,R) can be programmed directly into the program.The block after a block with C or R, must be a block with G01.Programming a chamfer is only possible with the comma symbol «,C», otherwise an error message appears because of unauthorized use of the C-axis.

• Input of angles (,A) is possible only with the comfort programming option.

• The following G-commands should not be used for blocks with chamfer or radius:

G-commands in Group 00:G7.1, G10, G11,G52, G53,G73, G74, G76, G77, G78

G-commands in Group 01:G02, G03, G-commands in Group 06:G20, G21

• These must not be used between blocks with chamfer or radius which define the sequence numbers.

Helical interpolation

Normally, only two axes are given for a circle and these also determine the planes in which the circle is.

If a third, vertical axis is given, the movements of the axis carriages are coupled in such a way that a helical line results.The programmed feed speed is not observed on the actual path, but on the circular (projected) path. The third axis, moved in a straight line, is also controlled so that it reaches the end point at the same time as the axes moved in a circle.

X,Y, Z, ……. End point of the arc

I,J, K………. Incremental circular parameter (Distance from start point to the

cle for -R, can be given instead of the parameters I, J, K.

The tool is moved along the defined arc to the objective with the feed programmed under F.

Notes

• You can only run a circular interpolation in the active plane.

• If I, J or K are equal to 0, the relevant parame-ters must not be given. The turning direction for G02, G03 is always considered vertically on the active plane.

G40 Deselection mill radius off-set

G40 deselects mill radius offset.Deselection is possible only in connection with a straight-line traverse movement (G00, G01).G40 can be programmed in the same block as G00 or G01 or in the preceding block.G40 is usually defined in the withdrawal to the tool change point.

Radius offset tool path

Definition of G42 Mill radius correction right

G42 Mill radius offset right

If the tool (viewed in the feed direction) is to the right of the contour to be machined, G42 must be programmed.

For instructions see G41!

G41 Mill radius offset left

If the tool (viewed in the feed direction) is to the left of the contour to be machined, G41 must be programmed.So that a radius can be calculated, when selecting the mill radius offset, you must state a D param-eter from the table: Tool correction => TOOL RADIUS OFFSET gaps => GEOMETRY AND WEAR which equals the mill radius, e.g. N.. G41 D..

Notes• A direct switch between G41 and G42 is not

allowed — prior deselection with G40.• Approach in connection with G00 or G01 re-

quired.• The mill radius data is essential, the H param-

eter is effective only until it is deselected with H0 or a different H parameter is programmed.

Mill radius offsetIf mill radius offset is used, a parallel contour path will be calculated by the controller automatically and the mill radius compensated in this way.

G52 Local coordinates system

FormatN.. G52 X.. Y.. Z..

G52 offsets the instantaneous coordinate source around the X, Y and Z values. Use this to create a sub-coordinate system to the existing coordinate system.

The programmed offset is maintained until a dif-ferent offset is called.

G53 Machine coordinates sys-tem

FormatN.. G53

The machine zero point is set by itsmanufacturer (EMCO milling machines: at the left front edge of the machine table).

Certain work steps (tool change, measurement position, etc.) are always executed at the same position in the workspace.

G53 disables the zero point offset for a program block ans the coordinate data is related to the machine zero point.

G54-G59 Zero point offsets 1-6

Six positions in the workspace can bepreset as zero points (e.g. points on fixed mount-ed clamping devices). These zero point offsets are called with G54 — G59.

or G65 Pxxxx Lrrrr Arguments

Xxxx is the macro number (e.g. O0123) • rrrr the repetition value• «program.CNC» is the name of the macro file • Arguments is a list of variable designators and

values.

Arguments for macro calls are given by using the letters A-Z, excluding G, L, N, O and P. Macros are written like normal programs. Howev-er, macro programs can access their arguments with numbers: #1 for A, #2 for B etc. (exceptions: # 4-6 for I-K, # 7-11 for D-H).

A macro can use the negative of an argument with a minus sign in front of the ‘#’. Other computing operations are not supported.Macros can call other macros (up to 4 levels in depth), macro M-functions and sub-routines. Mac-ro M-functions and sub-routines can call macros.

Drilling Cycles G73 — G89

G98 ……After reaching the drilling depth the tool retracts to the start plane

G99 ……After reaching the drilling depth the tool retracts to the withdrawal plane- defined by the R parameter

Is no G98 or G99 active, the tool retracts to the start plane. If G99 (Withdrawal to the withdrawal plane) is programmed the address R must be programmed. With G98 R need not to be pro-grammed.

The compution of the R parameter is different with incremental and absolute programming:

Absolute programming (G90):R defines the height of the withdrawal plane over the actual workpiece zero point.

Incremental programming (G91):R defines the height of the withdrawal plane re-lated to the last Z position (start position of the drilling cycle). With a negative value for R the withdrawal plane will be below the start position, with a positive value the withdrawal plane will be over the start position.

Sequence of movements

1: The tool traverses with rapid speed from the start position (S) to the plane defined by R (R).

2: Cycle-specific drill machining down to end deptht (E).

3: The withdrawal occurs a: with G98 to the start plane (S) and b: with G99 to the withdrawal plane.

Number of repetitions

The K parameter defines the number of repetiti-ons of the cycle.With absolute programming (G90) it would make no sense to drill several times in the same hole.With incremental programming (G91) the tool mo-ves on each time for the distances X and Y. This is a simple way of programming rows of borings.

Make sure that G98 is active!

G90 Absolute value programming

FormatN.. G90

There are two ways to program travels of the tool: the absolute programming, and the incrementalprogramming.In the absolute programming, coordinate value of the end position is programmed.The incremental programming is used to program the amount of a tool movement.

Notes• A direct change between G90 and G91 is also

allowed block by block.• G90 (G91) may also be programmed in conjunc-

tion with other G-functions: (N… G90 G00 X… Y… Z…)
