Page 27 Chapter II Operation Program Editing 2.2.1 Programming Overview 2.2.1.1. Part Programs Prior to part machining, the part shape and machining conditions must be converted to a program. This program is called a part program. A comprehensive machining plan is required for writing the part program. The following factors must be taken into account when developing the machining plan: Determine the machining range requirements and select a suitable machine.
Page 28 HUSTCNC-H4CL-T Manual Good capability in setting chucks. Good capability in determination of part material. Two programming methods are available for the part program of the numerical control unit: □□ Manual Programming □□ Automatic Programming Manual Programming All processes from drawing of the part diagram, machining design, numerically controlled program algorithm, programming, to the transmission of the program and the controller are performed manually.
Page 29 Chapter II Operation 2.2.1.3. Program Composition A complete program contains a group of blocks. A block has a serial number and several commands. Each command is composed of a command code (letters A~Z) and numeric values ( ＋ , － ,0~9). An example of a complete part program containing 10 blocks is shown in the table below.
Page 30 HUSTCNC-H4CL-T Manual Function Command: The G-code, for example, is used to instruct the machine to perform actions, such as linear cutting, arc cutting, or thread cutting. Positioning Command: X, Z, U, W commands, for example, instructs the G-code of the machine to stop at a specified position; i.e. destination or end point of the action.
Page 31 (positioning control). * Coordinate Axis The H4CL-T Series uses the well-known 2-D Cartesian coordinate system. The two axes used in the lathe series are defined as X-axis and Z-axis. The Z-axis is 2 - 23...
Page 32 When the spindle is rotating, your thumb points to the positive direction of the Z-axis and four fingers point to the direction of normal rotation. * Coordinate Positioning Control The coordinate of the H4CL-T Series is either absolute or incremental, depending on the command code of the coordinate axis, i.e.: X, Z: Absolute coordinate commands.
Page 33 Chapter II Operation direction, U, W represents an increment. If it is heading to the negative (-) direction, U, W represents decrement. X, Z and U, W are interchangeable in the program. The commands used for absolute and incremental coordinates are described as follows: Absolute Commands: (Fig.

Page 35 Chapter II Operation The programmer determines the position of the work origin. It can be any point on the centerline of the spindle. However, it is recommended to select an origin that makes reading of the work-piece coordinate easier. The X-axis of the work origin should be on the centerline of the lathe spindle.
Page 36 HUSTCNC-H4CL-T Manual For the H4CL-T Series controller, the machine origin is the stop position of the tool when the homing for each axis is complete. As Fig. 2-30 shows, the machine origin corresponding to the coordinate used to indicate the work origin varies depending on the position of the work origin.

Page 50 HUST CNC-H4CL-T Manual Fast Positioning, G00 Format: G00 X(U)____ Z(W)____ X, Z : End point in absolute coordinates. U, W : End point in incremental coordinates relative to the block starting point. Fig. 3-1 Fast positioning G00 (or G0 ) is used to instruct the tool to move to the defined end point of a program block at the maximum speed of MCM #33.
Page 51 Chapter III G/M Codes 3.05 3.00 2.00 Fig. 3-2 G00 Programming Example Tool moves to X4.00, Z5.60 rapidly. Since both X and Z axes are repositioning, the tool moves according to the lower feed-rate set in the parameter “Highest Feed-rate”.Ex: Fig.
Page 52 HUST CNC-H4CL-T Manual G01 (or G1) is used for linear cutting work. It can control the X, Z-axes simultaneously. The cutting speed is determined by the F-code. The smallest setting value of the F-code is 0.02 mm/min or 0.2 in/min. The starting point is the coordinate of the tool when the command is given.
Page 53 Chapter III G/M Codes G02, G03 Arc Cutting The arc-cutting program contains four command groups, as showed in the list below. The combination of these commands determine the arc path of the tool in a single block. Command Description Arc feed direction Clockwise Counter clockwise End point...
Page 54 HUST CNC-H4CL-T Manual An arc comprises three elements, a start point, and end point and a center (See Fig. 3-5). The start point (S) is the tool coordinates when the G02 and G03 execute. The end point (E) is the coordinates of X (U) and Z (W) in the program format. The center (C) is defined by I and K values.
Page 55 Chapter III G/M Codes G03 X(U)____ Z(W)____ I____ K____ F____ Start Fig 3-7 G03 Arc Cutting G02 X(U)____ Z(W)____ R____ F____ Start Fig. 3-8 Defined by Radius “R” Example: The following four commands are different in settings but execute the same arc cutting work.
Page 56 HUST CNC-H4CL-T Manual There are two different arc types available for arc cutting (Fig. 3-10): Use “+R" if arc angle < 180 ° . Use “-R" if arc angle > 180 ° . R is within the range from -4000.mm to +4000.mm. Ex: In Fig.
Page 57 Chapter III G/M Codes Dwell Command, G04 Format: G04 X____ X: Dwell time in sec (the X here indicates time rather than position). To meet machining requirements, the axial movement may need to be held during the execution of a program block, which completes before the command for the next block is executed.
Page 58 HUST CNC-H4CL-T Manual Return to Previous Position from Reference Point, G29 Format: G29 X____Z____ The X, Z, values in this format are not used. They only indicate the set of axes to return to the previous position from the reference point. When the tool returns to the position before G28 is executed, use the G29 command.
Page 59 Chapter III G/M Codes Skip Function, G31 Format: G31 X (U)____ Z(W)____ X, Z: Predicted end point in absolute coordinates U, W: Predicted end point in incremental coordinates relative to the starting point. Defined skip point. To ensure a valid skip function G31, it must be used in combination with an I/O signal.
Page 60 HUST CNC-H4CL-T Manual ． Note that G31 cannot be used in the tool radius compensation state. G40 must be executed to cancel the tool radius compensation before G31 is given. ． The skip function is invalid during the program dry run, feed-rate adjustment and auto acceleration/deceleration.
Page 61 Chapter III G/M Codes Both fine cut and rough cut of the thread cutting proceed along the same path. The cutting action on the Z-axis does not start until the Grid signal is received from the spindle. All repeated cutting actions start at the same point. Due to delay of the server system, imperfections could result at both ends of the thread (S1 and S2).

Page 191 Chapter II Operation Program Editing 2.2.1 Programming Overview 2.2.1.1. Part Programs Prior to part machining, the part shape and machining conditions must be converted to a program. This program is called a part program. A comprehensive machining plan is required for writing the part program. The following factors must be taken into account when developing the machining plan: Determine the machining range requirements and select a suitable machine.
Page 192 HUSTCNC-H4CL-T Manual Good capability in setting chucks. Good capability in determination of part material. Two programming methods are available for the part program of the numerical control unit: □□ Manual Programming □□ Automatic Programming Manual Programming All processes from drawing of the part diagram, machining design, numerically controlled program algorithm, programming, to the transmission of the program and the controller are performed manually.
Page 193 Chapter II Operation 2.2.1.3. Program Composition A complete program contains a group of blocks. A block has a serial number and several commands. Each command is composed of a command code (letters A~Z) and numeric values ( ＋ , － ,0~9). An example of a complete part program containing 10 blocks is shown in the table below.
Page 194 HUSTCNC-H4CL-T Manual Function Command: The G-code, for example, is used to instruct the machine to perform actions, such as linear cutting, arc cutting, or thread cutting. Positioning Command: X, Z, U, W commands, for example, instructs the G-code of the machine to stop at a specified position; i.e. destination or end point of the action.
Page 195 (positioning control). * Coordinate Axis The H4CL-T Series uses the well-known 2-D Cartesian coordinate system. The two axes used in the lathe series are defined as X-axis and Z-axis. The Z-axis is 2 - 23...
Page 196 When the spindle is rotating, your thumb points to the positive direction of the Z-axis and four fingers point to the direction of normal rotation. * Coordinate Positioning Control The coordinate of the H4CL-T Series is either absolute or incremental, depending on the command code of the coordinate axis, i.e.: X, Z: Absolute coordinate commands.
Page 197 Chapter II Operation direction, U, W represents an increment. If it is heading to the negative (-) direction, U, W represents decrement. X, Z and U, W are interchangeable in the program. The commands used for absolute and incremental coordinates are described as follows: Absolute Commands: (Fig.

Page 199 Chapter II Operation The programmer determines the position of the work origin. It can be any point on the centerline of the spindle. However, it is recommended to select an origin that makes reading of the work-piece coordinate easier. The X-axis of the work origin should be on the centerline of the lathe spindle.
Page 200 HUSTCNC-H4CL-T Manual For the H4CL-T Series controller, the machine origin is the stop position of the tool when the homing for each axis is complete. As Fig. 2-30 shows, the machine origin corresponding to the coordinate used to indicate the work origin varies depending on the position of the work origin.

U, W : End point in incremental coordinates relative to the block starting point. Fig. 3-1 Fast positioning G00 (or G0 ) is used to instruct the tool to move to the defined end point of a program block at the maximum speed of MCM #33.
Page 215 Chapter III G/M Codes 3.05 3.00 2.00 Fig. 3-2 G00 Programming Example Tool moves to X4.00, Z5.60 rapidly. Since both X and Z axes are repositioning, the tool moves according to the lower feed-rate set in the parameter “Highest Feed-rate”.Ex: Fig.
Page 216 HUST CNC-H4CL-T Manual G01 (or G1) is used for linear cutting work. It can control the X, Z-axes simultaneously. The cutting speed is determined by the F-code. The smallest setting value of the F-code is 0.02 mm/min or 0.2 in/min. The starting point is the coordinate of the tool when the command is given.
Page 217 Chapter III G/M Codes G02, G03 Arc Cutting The arc-cutting program contains four command groups, as showed in the list below. The combination of these commands determine the arc path of the tool in a single block. Command Description Arc feed direction Clockwise Counter clockwise End point...
Page 218 HUST CNC-H4CL-T Manual An arc comprises three elements, a start point, and end point and a center (See Fig. 3-5). The start point (S) is the tool coordinates when the G02 and G03 execute. The end point (E) is the coordinates of X (U) and Z (W) in the program format. The center (C) is defined by I and K values.

Page 225 Chapter III G/M Codes Both fine cut and rough cut of the thread cutting proceed along the same path. The cutting action on the Z-axis does not start until the Grid signal is received from the spindle. All repeated cutting actions start at the same point. Due to delay of the server system, imperfections could result at both ends of the thread (S1 and S2).
