ACU-RITE MILLPWRG2 171 8.1 Milling and Drilling Rectangle frame When you program a rectangular frame, you define it by its first corner, and its size or diagonal corner. You can program a frame in one of three ways: Using the coordinates of two diagonal corners. Using the coordinates of one corner and the size of the frame. Using the coordinates of the center and the size of the frame. To program a rectangular frame: From the PGM screen, press the RECT key to access the RECT popup Menu. Select Frame from the popup Menu. Entering data: Enter the 1st Corner X1 and Y1 axes coordinates. Now enter either the Size of the frame or the 2nd Corner coordinates. Either data entry will automatically fill in the fields for the for the other option. To enter the Size, enter the length of the frame along the X and Y axes. Or enter the X and Y axes coordinates for the 2nd Corner. The 2nd corner must be located diagonally from the 1st corner. Enter the Begin and End depths for Z. Enter either the number of passes or the distance between each pass. Pass refers to the cuts that are used to machine the frame to its End depth. Which choice is shown in the dialogue was selected in Job Setup. Enter the Z axis Feed Rate.
1728 Milling and Drilling 8.1 Milling and Drilling Add a corner blend radius or a chamfer to the corners of the rectangular frame. For Direction, press either the CW soft key for a clockwise cutting direction or the CCW soft key for a counter-clockwise cutting direction. ARROW DOWN or press the More soft key and select the Tool Offset. ARROW DOWN or press the More soft key and enter the table’s feed rate. Enter the Center X and Y axes coordinates. You can tilt a rectangular frame by identifying a tilt angle. Highlight the Angle field and enter an angle measured from the X axis. Finish: Finish allows you to leave some excess material that will be removed during the finish cut reducing tool marks. The finish cut will automatically arc on and arc off. Enter the amount of material to be removed during the finish cut in the Cut field. Enter the Feed Rate for the finish cut. Select the finish cut’s Direction. Press the CW soft key for a clockwise direction or the CCW soft key for a counter-clockwise direction. Press the USE key. If the tool size and type listed in the Tool field are incorrect, change the tool settings before running your program. Tool path description: Machining of the frame begins at the center of the line forming the top of the rectangle. The tool plunges at the Z feed rate. The frame is milled in the direction programmed (CW or CCW) The Z step size is determined by the system and will not exceed the specified distance or number of passes. The side finish allowance is optional and is only applicable to frames with a tool offset. If specified, this amount is left on the side of the frame to be removed on the finish pass. When finish feed is 0, the finish pass will be skipped.
ACU-RITE MILLPWRG2 173 8.1 Milling and Drilling Rectangle face The “Rectangle Face” step provides a quick way to face off your workpiece. Simply enter the coordinates from one corner and either the size of the area to be faced off or the coordinates for a diagonal corner. MILLPWR G2 will position your table at the lower left end of the area youve programmed. You can program a rectangle face in one of two ways: Using the coordinates of two diagonal corners. Using the coordinates of one corner and the size of the face. Using the coordinates of the center and the size of the face. To program a rectangular face: From the PGM screen, press the RECT key to access the RECT popup Menu. Select Face from the popup Menu. Entering data: Enter the 1st Corner X1 and Y1 axes coordinates. Now enter either the Size of the face or the 2nd Corner coordinates. Either data entry will automatically fill in the fields for the for the other option. To enter the Size, enter the length of the face along the X and Y axes. Or enter the X and Y axes coordinates for the 2nd Corner. The 2nd corner must be located diagonally from the 1st corner. Enter the Begin and End depths for Z. Enter either the number of passes or the distance between each pass. Pass refers to the cuts that are used to machine the face to its End depth. Which choice is shown in the dialogue was selected in Job Setup. Enter the Z axis Feed Rate. ARROW DOWN or press the More soft key. Enter the Center X and Y axes coordinates. You can tilt the face by identifying a tilt angle. Highlight the Angle field and enter an angle measured from the X axis. Enter a stepover percentage (how much the tool to is to overlap on each pass) for the Finish pass.
1748 Milling and Drilling 8.1 Milling and Drilling Tool path description: Machining of the face begins near the first corner. The tool plunges at the Z feed rate. The tool makes back and forth passes in the XY plane along the defined length of the face. Tool motion extends beyond the ends of the rectangle by an amount equal to the tool radius. The XY step size is determined by the system and will not exceed the specified percentage of the tool diameter. The Z step size is determined by the system and will not exceed the specified distance or number of passes. The tool retracts to the active datums retract position between Z passes.
ACU-RITE MILLPWRG2 175 8.1 Milling and Drilling Rectangle slot You can program a slot two ways: By entering the center point of each arc and the slots width By entering the center point of one arc, the length and width of the slot, and an angle. Using the coordinates of the center and the length of the slot. By entering the center point of the slot and the slots width and length. Choose a method based upon the information available from your print. To program a slot: From the PGM screen, press the RECT key to access the RECT popup Menu. Select Slot from the popup Menu. Entering data: Enter the 1st Arc Center X1 and Y1 axes coordinates. Now enter the size of the pocket in the 2nd Arc Center fields X2 and Y2 axes coordinates. Enter the Begin and End depths for Z. If this information was entered on a previous program step, it will automatically be displayed. If necessary, adjust the data for this program step. Enter either the number of passes or the distance between each pass. Pass refers to the cuts that are used to machine the slot to its End depth. Which choice is shown in the dialogue was selected in Job Setup. Enter the Z axis Feed Rate. For Direction, press either the CW soft key for a clockwise cutting direction or the CCW soft key for a counter-clockwise cutting direction. Enter the Slot Width. The slot length will automatically be calculated. ARROW DOWN or press the More soft key and enter the table’s feed rate. Enter the Center X and Y axes coordinates.
1768 Milling and Drilling 8.1 Milling and Drilling The Tool fields will automatically be filled in with the current tool loaded. If a different tool is to be used, enter a Set Tool step prior to this program step. You can tilt a rectangular slot by identifying a tilt angle. Highlight the Angle field and enter an angle measured from the X axis. The Finish fields will assume the same as the previous finish fields in the program if it exists. Otherwise this data must be added if necessary to include it. Leave it blank if it is not required. For Direction, press either the CW soft key for a clockwise cutting direction or the CCW soft key for a counter-clockwise cutting direction. Enter a stepover percentage (how much the tool to is to overlap on each pass). Press the USE key. Tool path description: Machining of the slot begins at its first arc center location. The tool ramps or plunges at the Z feed rate. The slot is milled from the center out. The XY step size is determined by the system and will not exceed the specified percentage of the tool diameter. The slot is machined at the feed rate programmed in the step. When the tool makes a cut greater than the step over such as the initial cut down the center of the slot, the full cut override is applied to the feed. The full cut override only applies to the rough pass. The finish pass runs entirely at the programmed finish feed. The Z step size is determined by the system and will not exceed the specified distance or number of passes. The tool retracts slightly (0.1 or 2 mm) between Z passes. A finish allowance is optional. If specified, this amount is left on the bottom and sides of the pocket to be removed on the finish pass. When finish feed is 0, the finish pass will be skipped. Finish direction applies to both the bottom and side finishes.
