This is the capacity group that will perform the operation. Various details specified for the relevant capacity group are retrieved on the operation line.

The machine you enter here is copied for information purposes to the production calculation when you copy the calculation to a production file. You can use the machine in presets and reports.

It is not possible to plan by machines. You can, however, register hours against a machine, via the operation corresponding to the machine. In that case, the machine rate determines the actual costing. Cost estimates are always made based on the capacity group.

Employees can be linked to an operations schedule, in order to allow you to schedule using labor hours. To link one employee to an operation, select this employee in the Employee field on the Operations calculation form or the Production calculation for operations form. To link multiple employees to an operation line, click the Personnel button on the calculation form or the production calculation form.

This field shows the total number of times that the action must be performed. If the standard capacity is used in calculations, this field is important for the calculation of the total cycle time.

The informational field next to the quantity allows you to enter a unit, for example 'pieces' or 'pipes'.

Enter a description of the component that is to be processed. This description could, for example, be printed on work orders. If you need more space, you can use the memo pad at the bottom of the Memo tab.

The Fixed lead time field allows you to specify a lead time that should always be used for the capacity group.

If the value of the field is '1' or higher, the fixed lead time will always be used in the planning process. Even if the cycle, setup and adjustment times of the operation were to require a longer lead time than the fixed lead time specified, the planning will still use the lead time specified. This field therefore allows the planner to use a lead time that differs from the lead time calculated by the software.

If the capacity group is included in a part or production calculation, the fixed lead time will be used in the calculation. The field value can still be modified here.

If you do not want to use a fixed lead time, set the field to '0'.

If the default calculation has been copied from the Parts module to a production file, the fixed lead time can still be changed in the production file. The value in the part calculation is just a default value.

Refer to the overview in the Which lead time is used in the planning? section for information about the role of the fixed lead time in the planning.

The standard capacity is the regular capacity for this capacity group, for example '10 pieces per hour' or '5 minutes per piece'. The standard capacity can be used when calculating the time required to perform the operation (see the Total machine cycle time field). This depends on the setting of the Use standard capacity check box.

If the Use standard capacity check box is selected, the total cycle time for the machine will be calculated based on the Quantity field and the Standard capacity field. If the Use standard capacity is not selected, you fill in the setup, adjustment and cycle times manually.

If the Use standard capacity is not selected, but you do want the cycle times to be calculated based on the quantity and the standard capacity, open the Settings menu and choose the Calculate machine cycle time based on quantity and standard option.

Remarks

The Use standard capacity setting is configured in the capacity group settings. When you select this check box, the standard times set for the capacity group will be copied to the setup/adjustment times and standard capacity of the operation line to which you are adding the capacity group. The total cycle times are then calculated on the basis of the quantity specified on the operation line.

Although you can no longer change the setup and adjustment times if the Use standard capacity check box is selected, it is possible to specify a different standard capacity. In that case, the total cycle time for the machine will be calculated based on the new standard capacity.

Note: The standard capacity can be specified in 'Minutes per piece' or in 'Quantities per hour'. The unit displayed on your screen depends on the setting in the Basic data form, Settings tab, Standard capacity unit field.

Note: Please think carefully before changing the standard capacity unit in the General Settings module. Changing the unit has far-reaching consequences for the calculations already present in Isah.

Tip: To ensure that the standard capacity on this operation line always has the same value as the standard capacity that has been set for the capacity group, leave the chain intact (). To prevent the standard capacity in this calculation from changing when the standard capacity for the capacity group is changed, break the chain (). The chain icon for the standard capacity is available only in the operation calculation in the Parts module.

If the Use standard capacity check box is selected, the total cycle time for the machine will be calculated based on the Quantity field and the Standard capacity field. If the Use standard capacity is not selected, you fill in the setup, adjustment and cycle times manually.

The Use standard capacity check box can be selected or deselected only in the capacity group settings.

If the Use standard capacity is not selected, but you do want the cycle times to be calculated based on the quantity and the standard capacity, open the Settings menu and choose the Calculate machine cycle time based on quantity and standard option.

If this calculation line is part of the calculation of a phantom part (a semi-finished product for which the product calculation is copied to the calculation), this field shows the line that contains the phantom part. This enables you to see which calculation lines are part of a phantom part.

The machine setup time is the time needed to set up one or more machines before an operation can start. This time consists of the machine hours required to get a machine ready for production; the required number of labor hours is shown in the Setup labor time field.

If the Use standard capacity check box is selected, the setup/adjustment time cannot be changed. In that case, the setup/adjustment time will be retrieved from the capacity group details.

The setup labor time is the labor time needed to set up one or more machines before an operation can start. This time consists of the labor hours required to get a machine ready for production; the required number of machine hours is shown in the Machine setup time field.

If the Use standard capacity check box is selected, the setup/adjustment time cannot be changed. In that case, the setup/adjustment time will be retrieved from the capacity group details. If the Labor time equals machine time check box is selected (General Settings module, Settings folder, Basic data, Calculations tab), the time cannot be changed either.

The standard overhead rate is retrieved from the capacity group. The value for this operation line is calculated based on the machine hours.

The machine cycle time is the machine time required to perform the operation. If the Use standard capacity check box is selected, the total cycle time for the machine will be calculated based on the Quantity field and the Standard capacity field. If the Use standard capacity is not selected, you fill in the setup, adjustment and cycle times manually.

The cycle labor time is the labor time required to perform the operation.

If the Use standard capacity check box is selected, you cannot change this field value, and the cycle labor time will be retrieved from the capacity group. If the Labor time equals machine time check box is selected (General Settings module, Settings folder, Basic data, Calculations tab), the time cannot be changed either.

The standard overhead rate is retrieved from the capacity group. The value for this operation line is calculated based on the machine hours.

The machine adjustment time is the time needed to clean and power off a machine after an operation has finished. This time consists of the machine hours required to power off a machine; the required number of labor hours is shown in the Adjustment labor time field.

If the Use standard capacity check box is selected, the setup/adjustment time cannot be changed. In that case, the setup/adjustment time will be retrieved from the capacity group details.

The adjustment labor time is the time needed to clean and power off one or more machines after an operation has finished. This time consists of the labor hours required to power off a machine; the required number of machine hours is shown in the Machine adjustment time field.

If the Use standard capacity check box is selected, the setup/adjustment time cannot be changed. In that case, the setup/adjustment time will be retrieved from the capacity group details. If the Labor time equals machine time check box is selected (General Settings module, Settings folder, Basic data, Calculations tab), the time cannot be changed either.
